Experimental Studies on Effect of Alccofine in Workability and Mechanical Properties of Fiber Reinforced Concrete

Fibers are usually used in concrete to control cracking due to plastic shrinkage and to drying shrinkage. They also reduce the permeability of concrete and thus reduce bleeding of water. Some types of fibers produce greater impact, abrasion, and shatter resistance in concrete. Fibers that are too long tend to "ball" in the mix and create workability problems. Alccofine is a specially processed product based on slag of high glass content with high reactivity obtained through the process of controlled granulation. It is a pozzolanic material that can be utilized to produce highly durable concrete composites. Owing to its unique chemistry and ultra-fine particle size, it provides reduced water demand for a given workability. Experimental investigation will be carried out on determining the effect of alccofine on the mechanical properties and the workability of steel fiber reinforced concrete. For that steel fiber of length 5cm and 1mm diameter are added at percentages of 0.1, 0.25 and 0.5 by volume of concrete. And Alccofine is added at the rate of 5, 10, and 15 % by weight of cement. Experimental results show that Alccofine performs as a better workability agent as well as improves the strength of concrete.
