Investigating the Curing Conditions on the Mechanical Properties of Concrete Containing Brick Waste

Abstract

Today, the increase in construction has caused a shortage of building materials all over the world. On the other hand, the need to remove construction debris, environmental protection, optimal use of resources and recycled materials, and economic construction have made it possible to propose recycled materials as a suitable alternative source. Among the different recycled materials, we can mention recycled brick waste. In this study, concrete samples containing recycled brick waste were processed in 6 different conditions, then the samples were subjected to compressive strength, tensile strength and impact strength tests and their performance was evaluated.

The results show that the samples made with waste bricks with different replacement percentages with coarse-grained materials gain their compressive strength and tensile strength in the conditions of 3 days wet curing and the concrete samples made with waste bricks and replaced with materials Fine grain, they get their compressive strength and tensile strength in wet curing conditions of 7 days. Also, the results showed that the compressive strength and the tensile strength of waste bricks are decreasing.

The impact resistance of concrete with different percentages of replacing coarse-grained materials in the laboratory environment (dry curing conditions) showed better performance than other curing systems. Concrete samples with different percentages of replacement of waste bricks with fine grains showed higher impact resistance in fully wet conditions than other curing systems. The impact resistance with the presence of recycled brick has decreased in most cases compared to the control concrete.
