Production Of Artificial lightweight Aggegate Using Rick husk Ash

Abstract

The demand for construction materials is increasing rapidly due to the growth of the construction industry worldwide. However, the aggregates used in concrete are typically collected from natural resources, which are limited. The continuous collection of these natural resources indicates their depletion, which could be a threat to all life on Earth. On the other hand, waste disposal from industries is a major issue in terms of sustainable development. Recycling is introduced in many countries worldwide to reduce pollution from industrial waste. A better sustainable system largely depends on recycling and reducing waste materials generated by different types of industries. These waste materials can be utilized by producing new materials like lightweight aggregates. The non-accessibility of natural lightweight aggregates and their increasing demand worldwide necessitates the development of new alternatives for producing artificial aggregates. The world is tremendously inspired by the innovative creation of alternative materials in the development industry as of late utilizing industrial by-products, the huge-scale use of these modern side-effects lessens ecological contamination and decreases the scarcity of aggregates. Subsequently, there is a requirement for, the generation of artificial aggregates, which meets the present necessity of the industrial business. In this research work, lightweight aggregates were manufactured from industrial waste such as rice husk ash and a binding material like cement. Cement and rice husk ash were mixed concerning volume (0%, 5%, 10%, 15%, 20%, 25%) with water. The determination of unit weight, specific gravity & water absorption of artificial aggregate was carried out. Also, the aggregate crushing value (ACV) test and aggregate abrasion value test were performed. Different types of mixing ratios showed different values of unit weight, specific gravity, aggregate crushing value, and aggregate abrasion value. The unit weight of artificial aggregates was calculated, which ranged from 740 kg/m3 to 1050 kg/m3, and the value of specific gravity was laid between 1.80 and 2.10. According to the mixing ratio of cement and rice husk ash (15%), the best result was obtained.
