Mechanical, water absorption, efflorescence, soundness and morphological analysis of hybrid brick composites

ABSTRACT

Nowadays, Recyclability of huge quantity of waste materials generated in industries to form new materials. The current research is also focuses on utilization of waste materials produced by industry to form new hybrid brick for sustainable the environmental condition, technical aspects, and low production cost in construction field. In this paper hybrid brick specimens are manufactured using waste materials of clay, ceramic waste powder and sugarcane bagasse ash with various mix proportions. These bricks are tested in compression test, soundness test and water absorption test as per Indian Standards. It was observed that clay bricks incorporating ceramic waste powder (10%) and sugarcane bagasse ash (10%) exhibited high compressive strength, less water absorption, less efflorescence, good metallic ringing sound compared to other hybrid bricks leading to protect the environmental stability and keep away from hassle of ash disposal. The combination of ceramic powder and sugarcane bagasse ash residue increases the compressive strength of the clay samples (B2) to 27.2 MPa, and the composition of Brick B2 exhibits decreased water absorption percentage up to 11.4%.
