Abstract


Curing is a process which follows immediately after placing and finishing of concreting. It maintains satisfactory moisture content and temperature in concrete for period of time so that the desired properties may develop. Curing has a strong influence on the properties of hardened concrete. With proper curing concrete becomes stronger, more impermeable, and more resistant to stress, abrasion, and freezing and thawing.  Using of fiber in concrete may improve these properties but it increases the cost of concrete. This paper reports the results of a study conducted to assess the effect of ages of curing on durability and strength of fiber and non fiber reinforced concrete. Also a comparative study of cost per unit strength and cost per unit service life period is done in between fiber reinforced concrete and non fiber reinforced concrete with proper curing. The concrete cubes were prepared varying three water cement ratios and cured for different curing days. Bulk electrical resistivity test, ultrasonic pulse velocity test, compressive strength test, flexural strength test and carbonation depth test were performed for the cured cubes. From test result it is found that proper curing of traditional concrete is more economical than fiber reinforced concrete to achieve same strength and durability.
