A Study On The Compressive Strength Of Concrete Using Brick Aggregate And Two Diffrent Types Of Cement

Abstract

Concrete construction is becoming increasingly complex and the importance of producing structures that are both cost effective and durable has never been higher. Many experimental works have been performed to determine the compressive strength of different types of cement. The objectives of the study are to determine the compressive strength of concrete by using two different types of cement for grades M15 and M20. The materials used for the experiment are OPC & PCC Cement, Brick Chips, Sylhet sand and water. The mass of the specimens was recorded carefully. For 7 days, the values of compressive strength of concrete for OPC and PCC are 7.26 MPa and 7.30 MPa respectively of grade M15. For 28 days, the values are 11.39 MPa and 11.72 MPa respectively for the same types of cements for OPC and PCC of grade M15. For 7 days, the highest compressive strength of the concrete found 12.27 MPa for PCC of grade M20 and the lowest compressive strength is 7.26 MPa for OPC of grade M15. For 28 days, the highest compressive strength of the concrete found 14.27 MPa for PCC of grade M20 and the lowest compressive strength is 11.39 MPa for OPC of grade M15. The compressive strength of PCC cement was better than the OPC cement for the both grade M15 and M20.
