A Comparative Case Study on Mix Design of Recycled Brick Chip Concrete and Concrete with Other Aggregate Materials for a Particular Strength

Sayka Banu, and Mohammad Tanvir Rahman

The effects of aggregate type, size, and content on the behaviour of concrete is evident. It is well recognized that coarse aggregate plays an important role in concrete. Coarse aggregate typically occupies over one-third of the volume of concrete, and research indicates that changes in coarse aggregate can change the strength and fracture properties of concrete. To predict the behaviour of concrete under general loading requires an understanding of the effects of aggregate type, aggregate size, and aggregate content. This understanding can only be gained through extensive testing and observation. There is controversy, however, on the effects of coarse aggregate content on the compressive strength of concrete and the conditions to achieve the strength. Keeping this in mind, this paper deals with the actual amount of materials needed to achieve a particular strength, and the conditions, which greatly affect the gaining of this strength, putting special emphasis on different material conditions. It also puts an effort to find out the potentiality of recycled brick chips concrete along with other aggregates through compressive strength against time with different parameters.
