Effect of Destroyer Factors on Strength and Durability of Concrete Structures (with Special Review on Alkali-Silica (ASR) Reaction)

Abstract
In general, one of the most important goals that are considered in the construction of concrete process, are concrete durability and strength and it’s sustainability in different weather consitions. Therefore, it is necessary to pay attention to this issue in the various stages of concrete structures because they will have a direct influence on the life of the concrete structures and the cost of their maintenance. Identifying the destructive factors affecting concrete is another important factor. In this article, we try to study the conditions and factors affecting the durability of concrete, specially the Alkali -Silica Reaction(ASR). Keywords - Concrete, Alkali-Silica Reaction(ASR), Destroyer Factors, Durability, Strength.
