Aggregates make up some 60 80 of the concrete mix Fine Aggregate Vs Coarse AggregateFine aggregates generally consist of natural sand or crushed stone with most particles passing through a 38inch sieve Coarse aggregates are any particles greater than 019 inch but generally range between 38 and 15 inches in diameter Read More Using aggregate makes concrete much stronger with the aggregate acting as a type of reinforcement The aggregate increases the lifetime of the concrete and makes it more durable Contractors can choose from fine aggregates made from small particles of material and coarse aggregates which are made with large chunks

How Concrete is Made In its simplest form concrete is a mixture of paste and aggregates or rocks The paste composed of portland cement and water coats the surface of the fine small and coarse larger aggregates Through a chemical reaction called hydration the paste hardens and gains strength to form the rocklike mass known as concrete Within this process lies the key to a remarkable trait of One topsurface retarder product is Surface Deactivator by Brickform which provides ten exposure depths from a simulated light acid etch or sand blast finish up to full exposure of 1 aggregate Surface Deactivator offers an extended window before the surface paste is removed allowing the concrete to harden properly which locks in the aggregate and decreases popouts
