Academic literature on the topic 'KOTA STONE DUST'

The Kota city, which is situated in Rajasthan state of India, is having a major problem of disposing the quarry dust. Quarry dust is a waste product produced by the stone industry during the cutting and crushing of stone. This byproduct is affecting the environment and land fertility as well. One of the innovative techniques for ground improvement can be practiced by using quarry dust as soil stabilizing agent. This technique may simultaneously offer the environmental sustainability, use of industrial waste, and space saving. The Expansive Soil (ES) deposits in Kota district and its neighboring districts, Jhalawar and Baran, make it difficult to build large constructions. In order to make the soil suitable for construction, quarry dust and lime are used for stabilization of the ES in this study. The UCS and CBR value was increased after adding of quarry dust with 6% lime and stabilized soil has superior load bearing capacity.

Abstract This paper mainly deals with the cost analysis of the concrete which is prepared using environmental waste which forms pollution and having its disposable issue also. This concrete may be termed as green concrete because the use of these materials decreases the harmful gas formation of the concrete. This paper deals with Kota Stone Dust, Bagasse Ash, and Recycled coarse aggregates. The concrete is prepared by the various ratios of Kota Stone in order of 5%, 10%, 15%, 20%, 25% and 30%. The use of bagasse ash was done in ratio 10%, 20%, 30%, 40% and use of Recycled Aggregate was done in ratio of 10%, 20%, 30% and 40%. After the successful experimental study of concrete using this material the cost reduction for M25 grade of concrete was found to be 645 INR.

The tissue box is a place to store tissues to make them look neat and protect the tissues from dirt and dust. Tissue boxes are often used in households, restaurants and also as room decorations. Therefore, the shapes of tissue boxes that are being developed are increasingly varied according to consumer interests. The tissue box consists of three main parts, namely the cover, body and base of the box. This research was carried out by developing variations in the shape of the tissue box components using the Bezier curve, the Hermit curve and the results of the deformation of geometric objects. The deformation techniques used are rotation, dilation, and curve interpolation. Tissue box modeling processes are divided into four stages. The first, modeling the tissue box by dividing into three models, namely model A, model B and model C. The second, determining the size of the tissue box components based on the model. The third, modeling tissue box components. Finally, visualizing the results of the tissue box model by combining the components so that a variety of tissue box models are produced.

Background: Laparoscopic cholecystectomy is a gold standard for gall bladder stone surgery. The Aim and objective of study was to compare the total duration of surgery, intraoperative complication like bile leak from cystic duct stump, spillage of bile from gallbladder and post op pain and abdomen distension and jaundice.Methods: Study was carried out in dept. of gen Surgery, Govt medical college Kota in yr. 2015-16 in a total of 50 patients with cholelithiasis with cholecystitis. Patient were equally divided randomly into two groups (a) Harmonic scalpel group and (b) Titanium Clip and L hook group. All patients with medical comorbidities, Concomitant CBD calculi, cirrhosis and portal HT were excluded from study. Intraoperatively adhesions, bile spillage from GB and cystic duct stump noted Postoperatively complain like pain abdomen, Jaundice, and fever were noted. Duration of hospital stay was observed. All results were statistically analyzed using Chi square and ANOVA test.Results: Both groups were comparable on the basis of age and sex distribution, as no statistically difference was noted (P value 0.867 and 0.999 respectively). Intraoperative findings were adhesions 5 in clip group and 7 in harmonic group. Spillage from gall bladder was 2 in Clip group and 3 in harmonic group. Mean duration of surgery was 65.20 min in clip group and 63.68 in harmonic group with no statistically significant difference in both the group (P Value 0.727). Average duration of hospital stay was similar in both the groups with a mean of 2.6 days. Postoperative complication was fever, abdomen pain and distension were 3,1,1 were respectively in the clip group and 3,2,2 respectively in harmonic group with the P value of 0.999 which was statistically insignificant. No CBD injury was noted in any case. Conversion to open cholecystectomy was not done in any case. On 1week and 1 month follow up 2 cases in clip group and 1 in HS group had collection in gall bladder fossa and none at I month.Conclusions: Harmonic scalpel offers an effective, alternative and safe method to cystic duct division and Gallbladder dissection from liver bed.

This study examines the occurrence of glendonite along coastlines since 1825, which have been previously referred to under different names such as Pseudogaylussite, Fundylite, and Kool Hoot across eleven sites. By utilising element ratios and 14C radiometric dating techniques, we establish a more accurate chronology for these varied sites ranging from 10 to 1 thousand years before the present (Ky BP). Sites include tidal flats, coastal barrier islands, and Wadden Sea environments. While some sites still exist, others are only known through publications and museum collections. Our research expands upon previous findings by presenting petrographic evidence that correlates with glendonite formation. Through the examination of the Olenitsa site on the Kola Peninsula, we demonstrate that marine bioclasts enclosed within concretions surrounding glendonites provide temporal context, suggesting that these outcrops were formed during a single event under changing conditions. Notably, certain sediment structures at selected sites indicate the occurrence of cold-water ice-raft storm events and the presence of drop stones. Furthermore, our paper explores the association of historic coastal sites with the formation of ikaite, highlighting the limitations of relying solely on geochemistry and isotopic analysis for interpretation. Intriguingly, we observe that pseudomorphs are abundant in specific areas but absent in adjacent regions with similar environmental, physical, and chemical conditions. No apparent connection is found between volcanic dust cloud-induced cold spells and glendonite. The distribution of coastal glendonites is more likely related to periods of climatic cooling through other means. We show that radiometric dating with 14C provides an indication of age, but the results can be erroneous due to the inclusion of older carbon sources in the analysis. The oldest locations discussed in this study are Kool Hoot (Alaska) and the river Clyde (Scotland), and the youngest glendonites discussed are from the Bay of Fundy in Canada. Occurrences from the Wadden Sea are intermediate in age and sit between the other two groups. The age of the Olenitsa site on the Russian Kola Peninsula is uncertain and still debated. We show that measuring the ratio of Mg/Ca can indicate how much the recrystallised ikaite preserved as calcite is influenced by diagenetic pore waters.

With increased population their need and necessities also increasing day by day and to fulfill their needs industry ,urbanization are growing at a rapid rate and to provide energy various power plants as thermal, nuclear, hydro power plant also increasing. Due to rapid industrialization and power plant produces wastes which are a hazard to society such as Kota stone dust and Fly ash. Kota stone dust is a waste by product of Kota stone mines, Kota stone finishing industries. This waste product is disposed in river, on inhabited land area or on river sides. With wind or water this waste moves from their parent location and may come in contact with human and vegetation’s and cause pollution, gives inhalation problem and various diseases. To find out any kind of engineering use of this ecological hazard an attempt is made by mixing Kota stone dust with different proportion with expansive soil. This mix was tested for various engineering properties such as Atterberg’s limit, Standard proctor test and unconfined compression tests are performed. To compare the economy of Kota stone dust we did the all test as atterberg’s limit, standard proctor test, unconfined compression test are performed on samples formed by mixture of soil, Kota stone dust and fly ash in different proportion. Addition of Kota stone dust and fly ash both show increase in UCS value, increase in maximum dry density an decrease in optimum water content takes place.

This project report shows the result of laboratory study to investigate Kota stone dust mixing with black cotton soil and its effect on index properties of black cotton soil. Black cotton soil is very weak soil to bear the load of the structure and contains swelling and shrinking and highly compressible properties whenever change in water content takes place. So it is required to make it suitable for construction activities. So that improvement of black cotton soil is required with the mixing of admixture like as Kota stone dust. The essence of this project is to check out the feasibility of Kota stone dust as soil stabilization material. Number of laboratory experiments is required to investigate the effect of Kota stone dust with black cotton soil with the different proportion of it with 0% to 30% in the interval of 5%. Test results represent a quite change in consistency limit or Atterberg’s limit. Liquid limit decreases from 53.26% to 37.8%. Plastic limit changes from 29.76% to 29.12% with a very slight change in mixed proportion of soil. Liquid limit and plastic limit of black cotton soil decreases with increase in proportion of Kota stone dust. A big change is found in liquid limit but slight change in plastic limit takes place so overall plasticity index which shows plasticity behavior of soil also decreases up to a great extent. Plasticity index decreased from 23.5% to 8.68% with the addition of Kota stone dust from 0% to 30%. The differential free swell index decreased from 64.24% to 39.82% which shows that a reduction in swelling property of soil due to increase in the proportion of Kota stone dust which is a pozzolanic material and exerts friction in it due to coarser size particle of pozzolanic Kota stone dust. The unconfined compressive strength of soil is found maximum when Kota stone dust is mixed 10-20% with black cotton soil. The unconfined compressive strength of soil increases up to a certain limit after that it decreases. We found maximum UCS strength at the mixing of 15% Kota stone dust. Black cotton soil showed good UCS strength in the range of 10- 20% Kota stone dust. When soaked CBR test was performed so that improvement in CBR value was found maximum within the range of 20-25% mixing of Kota stone dust, it gives maximum CBR value so it is desirable to mix Kota stone dust in black cotton soil with a proportion of 20- 25% of mixing. CBR value mainly shows the soil behavior according to highway projects so Kota stone dust is useful in highway pavement design because it shows pozzolanic behavior of soil and frictional properties that causes good binding found in soil. Kota stone dust mixing with black cotton soil increases its maximum dry density in the range of 15-25% mixing of Kota stone dust. We found that in the range of 15-25% Kota stone dust maximum compaction of soil occur So it is helpful to make the soil dense by providing proper compaction and maximum dry density of soil. Standard Procter test was performed with heavy compaction during experiments so that it was found that dry density of soil increases up to a particular proportion of Kota stone dust in the range of 15-25% but continuous increase in water content was found with increase in its proportion. So a range of 15-25% is batter to make a highly compacted and dense soil. So that lots of experiment has conducted during this project and results are positive to stabilize soil by mixing of Kota stone dust mainly in the range of 15-20%. This range shows best mixture of kota stone dust with black cotton soil because all the laboratory results are giving satisfactory improvement in the geotechnical.
