Use of the largest permissible maximum size of coarse aggregate permits a reduction in cement and water requirements Using aggregates larger than the maximum size of coarse aggregates permitted can result in interlock and form arches or obstructions within a concrete form That allows the area below to become a void or …
[1] Basil Johny et al studied the properties of sustainable concrete using slag and recycled concrete aggregates. GGBS was replaced for 40%, 50% and 60% of cement and optimum percentage was found out. For the mixes prepared by replacing 50% cement with slag and 50% coarse aggregate, it satisfies the strength criteria required
These aggregate used for the construction of concrete and mortar must meet the following requirements. This should include natural stones, gravel, sand, or various mixtures of those materials. It should be inflexible, strong, and sturdy. It should be dense, clear, and free of any coating. Also, free from harmful vegetable issues.
