TO STUDY THE STRENGTH PARAMETERS OF CONCRETE USING SUGAR BAGASSE ASH, MARBLE WASTE POWDER AND RECYCLED AGGREGATE - Softcover

Inhaltsangabe

The demand of utilization of the waste product from the industries is at its peak therefore, several experimental investigations have been carried out to examine their physical and chemical properties when they are used as a replacement material in concrete. This lead to the revolutionary techniques which achieved high strength parameters. The crushed concrete is the most impeccable technique to produce the recycled aggregate. It can also be derived from any kind of concrete debris. The main advantage of recycled concrete aggregate (RCA) is that it resembles the same properties as that of concrete. Sugar bagasse ash (SBA) is the burnt by product of sugarcane’s bagasse. It is very fine and it becomes the main advantage of bagasse ash. Another type of replacement material is marble waste powder and it is derived by cutting and polishing the marble. In the present experimental study, which was conducted in an attempt to utilize these waste product, design mix of concrete was designed by partially replacing cement with bagasse ash, fine aggregate with marble powder and coarse aggregate with recycled concrete aggregate at varying proportions. Different tests were conducted in order to evaluate and determine its strength parameters. The gist, the conclusion which was made for the present study is that the compressive strength and flexural strength tends to increase at the beginning and gives maximum value for the design mix containing 20% SBA, 20% Marble Powder and 25% RCA and after this the strength starts to fall. The maximum split tensile strength was achieved with the design mix which entails 20% SBA, 40% Marble Powder and 25% RCA whereas, other mixes gives satisfactory result.
