Abstract :

 Here in this study floating concrete with lightweight aggregates (Pumice stone) and Aluminum powder as an air entraining agent is prepared. There are many types of lightweight concrete which can be produced either by using lightweight aggregate or by using an air entraining agent. Since this is a unique type of concrete hence authors found that very meager quantum of work is carried out in this regard hence authors have taken up this study under consideration, out of motivation. In this study we have worked on combination of above mentioned types. This concrete is a non–structural concrete. In this study, comparison has be made between plain cement concrete and lightweight concrete having different proportion of Aggregate size and fix quantity of Aluminum content (i.e. 2%) by the weight of cement has been taken into account. And also sawdust powder also has been used as partial replacement of fine aggregate. It helps to increase volume of concrete and hence reduce the weight. Different iterations in the form of samples were carried out and results were discussed below. However sample 4 turns out to be optimum for our mix proportion. This type of concrete reduces the cost of the project than the regular masonry structure. The optimum values for the light weight concrete of our sample 4 which is good for light weight concrete are with average density as 1102.66 kg/m3 and average compressive strength as 8.61, hence this satisfies the requirement of floating concrete.
