Mechanical Behavior of Porous Lightweight Concrete

Abstract

Concrete is widely used binding material for the construction purposes. It is material produced by mixing cement, sand and gravels in the given proportion. Porous concrete is special type of concrete that has low water cement ratio and contains little amount of sand thereby having open cell like structure which allows air and water to pass through it. Porous concrete is made by using large aggregate with little amount of fine aggregate and lightweight concrete is mixture made with cement and lightweight aggregate. It can be further classified into lightweight aggregate concrete, foamed concrete and autoclaved aerated concrete. The target of this analysis was to work out the mechanical behavior of porous lightweight concrete incorporating natural wastes such as saw wood cuts. This paper represents the properties of porous concrete with ideal amount of replace coarse aggregate (RCA). Five diverse types of porous concrete combine resembling M-15 grade of concrete consisting 0%, 20%, 30%, 40% and 50% of WA are get made to determine the compressive strength and also the split tensile strength. The compressive strength of the porous concrete with optimal alteration of coarse aggregate (CA) by 30% of Wood aggregate (WA) is attained close to regarding 100% of compressive strength of the M-15 grade of concrete
