Abstract

The use of concrete is truly large and day by day the cost of the conventional material cost is also rising. So, it is beneficial to use the optional materials for making concrete. The project focuses on coarse aggregate in concrete. In this project work, the study has been done on the replacement of coarse aggregate with demolished brick aggregate known as jhama bricks. The optional source is jhama brick as a coarse aggregate. The jhama brick is available from brick manufacturing area. This would not only make good use of the otherwise material but would also help alleviate disposal problems. The research was conducted to study the suitability of crushed over burnt brick as alternative coarse aggregate for concrete production. The concrete cube of M-25 grade was thrown in this trail explore work and try to analyze different properties of concrete with crushed over burnt bricks as an alternative material. The physical properties like compressive strength & workability with alternative material were used with a dosage of 0%, 10%, 20% & 30% in concrete with the age of 7and 28 days of curing.

In recent years, the construction industry has been growing rapidly, which has increased the demand for natural aggregates. At the same time, large amounts of waste materials are generated from brick kilns and construction activities. Jhama bricks, also known as over-burnt bricks, are one such waste material. These bricks are rejected because of their irregular shape but they have good strength. Instead of disposing them as waste, they can be crushed and used as coarse aggregate in concrete.

This paper reviews various research studies related to the partial replacement of natural coarse aggregate with Jhama brick aggregate. The effects on workability, compressive strength, tensile strength, flexural strength, density, and durability are discussed. From the reviewed studies, it is observed that up to 20–25% replacement can be used without major loss in strength. Hence, Jhama brick aggregate can be considered as a sustainable and economical alternative material for concrete.
