Abstract
Abstract Recently, interest set out for obtaining new recourses for natural aggregate ate used in concrete mixes. Attempts are also intensified to make use of the accumulation of certain types of construction and building residues such as bricks' fragments or the filler that results from the cutting of limestone and others to be used in concrete production as a partial replacement material of some of its components on the one hand and in order to achieve an economical benefit while executing the constructional projects on the other. The research aims at studying the effect of using porcelain crushed filler as a partial replacement material for the fine aggregate in the concrete mix and the effect of this on the concrete properties. In this research, the porcelain crushed filler was added in ( 0, 10, 20,30, 40)% replaced by the weight of the fine aggregate. Findings obtained have shown that the use of the porcelain crushed filler has affected the properties of concrete as it has caused a drop in the concrete density up to 6.07% at a replacement percentage of 40% and reducing its capacity of water absorption down to 17% at the same percentage. Findings have also shown the positive effect of the porcelain crushed filler on the compressive and tensile strengths with an increase reaching 18% at a replacement percentage 20% compared to the normal concrete.
