Aggregate in Concrete - The Concrete Network

Using larger coarse aggregate typically lowers the cost of a concrete mix by reducing cement requirements, the most costly ingredient. Less cement (within reasonable limits for durability) will mean less water if the water-cement (w/c) ratio is kept constant.

aggregate Topic - American Concrete Institute

 · Aggregates are the major constituent (ingredient) in concrete, making up 60% to 70% of the volume of concrete. Aggregates influence the workability of plastic concrete and also the durability, strength, thermal properties, and density of hardened concrete. Particle size divides aggregates into two categories: fine and coarse. Most fine aggregates are sand and contain …
