Abstract:Concrete is widely used in bridge construction because of its versatility, strength, durability, and low cost. It is a composite consisting of cement, water, coarse aggregates, fine aggregates, and admixtures to engineer the desired properties. During curing, concrete is subjected to changes in volume. These changes can cause cracking, which can allow corrosion and reduce the life of the deck. Maintaining the condition of bridge decks is one of the costliest components of bridge maintenance. There is a need to evaluate the effectiveness of various concrete mixes using different ways to mitigate shrinkage.
