Effect of Zeolite Inclusion on Some Properties of Concrete and Corrosion Rate of Reinforcing Steel Bars Imbedded in Concrete

摘要

In this paper, an experimental study has been conducted to evaluate the effect of zeolite inclusion as partial replacement on some properties of concrete containing zeolite and the effect of corrosion of reinforced steel bars imbedded in concrete. A total of 72 cubes were cast to determine compressive strength and 24 cylinder to determine the indirect tensile strength. Bond strength between reinforcing bars and concrete was determined by pullout test on 24 concrete blocks. Corrosion rate was studied and the results are presented. Different percentages of zeolite, namely 5, 10, 15, 20, 25, 30 and 35% were used which resulted in seven mixes other than the control one. The optimum replacement value was 15% by weight of cement at which all the studied properties has been enhanced.
