Different Types Sizes of Aggregate for Concrete ...

Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids. When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate.

Aggregate Concrete - an overview ScienceDirect

02-01-1992  Fakitsas et al. (2012) studied the effectiveness of internal curing using saturated RAs in SCC. The aggregates were submerged in water for 3 days and then surfaced dried for 12 h before being used in the concrete mixture. It was found that these soaked aggregates achieved an 80%–90% degree point of saturation.

A Review on Recycled Aggregates for the

For concrete with cylinder compressive strengths between 25 and 30 MPa, the modulus of elasticity of recycled aggregate concrete was only 3% lower than that of normal aggregate concrete. The trends in the development of compressive and shear strength and the strain at peak stress in RA concrete were similar to those in natural aggregate concrete.
