Evaluation the effect of cement kiln dust addition on absorption and some mechanical propertie of the concrete

Abstract EN

The goal of the present work is to investigate the effect of adding Cement kiln Dust (CKD), produced from Kufa cement plant on some properties of concrete.

Four different concrete mixes were prepared, with 0 %, 5 %, 10 % and 15 % CKD by weight of cement was replaced.

Two methods were used to study the absorption, the full immersion and the capillary rise.

The effect of absorption on some properties of concrete (compressive, tensile, flexural) strength was studied.

The compressive strength of concrete specimens decreased with the increasing of the quantity of CKD.

However, there was no significant difference in the compressive strength of 0 and 5 % CKD cement concretes.

A similar trend was noted in the splitting, flexural tensile strength and concrete absorption.

The performance of concrete with 5 % CKD was almost similar to that of concrete without CKD.
