Flexural strength evaluation of prestressed concrete beams with partial replacement of coarse aggregate by ceramic wastes

The present study deals with the improved performance on compressive and Flexural strength of Prestressed concrete beam with the effect of ceramic wastes by partial replacement of coarse aggregates, Experimental work was carried out to investigate the effect of ceramic wastes by partially replacing aggregate and using same quantity of water. In this program cube samples of size 150mm x150mm x 150mm for different percentage of ceramic wastes with partial replacement of aggregates were casted and tested. The concrete mixes had 5%, 10% of ceramic wastes replacing coarse aggregate partially, so as to determine the best proportion, which would give maximum compressive strength.

It reveals that with 5% ceramic wastes each partial replacement of coarse aggregate were found to be most favorable combinations for casting of prestressed concrete flexural members. There are two beam specimens of the same dimensions were casted and tested for their flexural strength. The dimensions of each beam were 125mm x 250mm x 3200mm. The beams were tested on universal testing machine (UTM) to verify their flexural strength after curing with two point load and. The results were compared with the beam of varying flexural strength.
