| dc.description.abstract | Concrete is a widely used structural material. Fine aggregate is one of the essential components of concrete. Natural river sand is the most commonly used for fine aggregate. However, increase in demand and depletion of river sand, along with restrictions imposed on the exploitation of the river sand, have resulted in search for a suitable alternative. On the other hand, industrial wastes have continued to increase due to the continued demands of resource use by humans and dumping or disposal of these materials causes environmental and health problems. Therefore, recycling of waste materials are great potential in concrete industry. Very recently, several researchers have used manufactured fine aggregate as a partial replacement of natural sand, and investigated its effect on major concrete properties. Similarly, Marble dust slurry, fine aggregate could be an alternative to natural sand. It is a by-product generated from stone industry during the production of Marble by Cutting and Finishing processes (wet process). Marble dust slurry, which are generally considered as a waste material, cause an environmental load due to disposal problem. Hence, the use of Marble dust slurry as fine aggregate in concrete and mortar mixtures will reduce not only the demand for natural sand but also the environmental burden. Moreover, the incorporation of Marble dust slurry fine aggregate will offset the production cost of concrete and mortar. In brief, the successful utilization of Marble dust slurry fine aggregate will turn this waste material into a valuable resource. The use of industrial and biogenic wastes in concrete as supplementary cementing materials is the present vital issue to obtain a sustainable environmental solution, save energy and natural resources. Some of the commonly used supplementary pozzolanic and cementing materials are rice husk ash (RHA), Silica fume, ground granulated blast furnace slag, fly ash and ash from timber etc. These waste can be found as natural materials, by-products or industrial wastes; these materials are also obtained with requiring low cost, energy and time. Rice husk, basically an agricultural residue, is obtained from rice processing mills of the developing countries. Only a small amount of produced husk is used as fuel in rice mill and electricity generating power plant. After burning rice husk, the RHA is produced as a by-product, about 20% of its original weight. In the present study, the replacement level of Marble dust slurry with natural sand (river sand) and Rice Husk Ash with cement optimised. The influence of optimised combination of MDS on fresh (slump) and hardened concrete properties (Compressive strength, flexure strength and Modulus of Elasticity) in concrete were assessed. Further, the possibility of using MDS in masonry mortar and plaster mortar was explored. An attempt was also made to standardise the mason defined consistency through an empirical apparatus. From the results obtained in this study, it is clear that the Marble dust slurry can be used as a suitable replacement material in concrete and mortar applications. In this project, the partial replacement of Rice husk ash with cement and Marble dust slurry with sand has been tested at different ratio such as 0%,5%10,%15%,20% and 25%. On the different mixture and different ratio of w/c, the cube of 150mm*150mm*150mm and 70.7mm*70.7mm*70.7mm has been tested on 7days, 28days and 90days. On the basis of above test, the partial replacement of Rice husk ash and Marble dust slurry, has given the better result. This research emphasises on the using waste materials, and this research can be useful to the construction industry. This will help us to save environment and improve the eco-system. We can conclude by above research that the partial replacement of Rice husk ash and Marble dust slurries, gives best compressive strength and flexural strength at the appropriate percentage i.e. 10% to 20%, but the strength reduced if the percentage of replacement is increased. | en_US |
