Durability of Concrete Factor Affecting Durable Concrete

Mar 20, 2019  The quantity of cement used in the concrete mix is a major factor affecting the durability of concrete. If the cement content used is lower than the required, then the water-cement ratio; gets reduced and concrete workability also gets decreased.; Adding more water to this concrete mix results in formation of capillary voids which will make concrete a permeable material inviting deterioration.
