An experimental study of cement mixture using construction waste

Abstract

This project is conducted to study whether the mixture of cement and construction waste powder can be a partial replacement of original cement. Due to the increasing of cement production cost, the cost of cement used by contractors in the construction field also increased. The objective of this project is to reduce the cost of cement used by contractors in the construction field and determine whether the mixture able to pass the European/Malaysian requirement standard. An experiment is carried out for mixture of cement and construction waste powder in order to produce a sample of mortar cube. The hammering process, crushing process, residue test, mixing process and also the compression test is used to determine the strength of the mixture. Contribution of this project is able to reduce the percentage of original cement used in construction. The reading obtained proved that this new mixture capable to fulfil the European standard requirements. In conclusion, this new cement mixture which consists of 90% OPC cement and 10% construction waste powder can be a new potential cement mixture.
