Abstract

The goal of this research is to reduce the need for Air Conditioning (AC) in buildings by limiting temperature dispersion from the exterior to the interior via building envelopes (walls). Hence two different hollow cavity blocks (circular and rectangular shape) have been cast and dimensions were given as per IS2185:2005. The compressive strength experiment for Recycled Aggregate Concrete (RAC) hollow block of two different cavity shapes with distinct substitution percentages of recycled aggregate (0%, 50%, 100%) was carried out by adding 25% coal ash as a replacement to cement. A basic property test of concrete materials is done followed by mix design (IS10262:2019). In this work, we attempt has been made to analyze the heat conduction through cavities in the concrete hollow blocks and circular hollow blocks made of recycled concrete aggregate using the Finite element analysis (FEA). A comparison of the characteristic strength and other properties of circular and rectangular cavities of recycled concrete hollow blocks has been discussed.
