Effect of curing condition on the engineering properties of fiber reinforced concrete

الملخص EN

The paper reports an experimental study investigating the influence of curing conditions on the engineering properties of fiber reinforced concrete (FRC).

Portland cement (PC) concrete and two types of FRC, i.e.

SFRC with 1 % by volume steel fiber reinforcement and PFRC with 1 % by volume poly propolylene reinforcement specimens are prepared and cured in two different curing conditions, namely water and air conditions for the periods of 3, 7, 14 and 28 days.

At the end of each curing periods, compressive and tensile strength and ultrasonic velocity (UPV) values are determined.

The results showed that water curd specimens always give the highest values then air condition irrespective of type and age of concrete and test method for both compressive and tensile strength tests, the PFRC gives the highest values followed SFRC and then PC concrete for all curing periods and conditions, also, the UPV results showed that the highest values are obtained from the PFRC and then from the SFRC and PC concrete for all curing conditions.
