A comparative study of over-burnt brick-based concrete with conventional concrete

Abstract A key aspect of sustainable development is the preservation of the natural environment. Due to the gradual depletion of natural resources, modern society is confronted with challenges in concrete that utilize a large number of natural resources. This paper strives to decrease reliance on natural resources, efficiently utilizing waste materials. The study examined the behavior of concrete by incorporating over-burnt brick aggregate as a partial replacement for natural aggregates ranging from 0 to 100%. A series of tests were conducted to assess the characteristics of aggregates and concrete. Through experiments it has been observed as replacement content increased, mechanical and durability tests consistently showed a decline in performance. Results showed replacement of up to 25% of C20/25 concrete grades without sacrificing structural integrity helps with sustainable development and makes better use of waste.
