Aggregates - Portland Cement Association

Grading limits and maximum aggregate size are specified because these properties affect the amount of aggregate used as well as cement and water requirements, workability, pumpability, and durability of concrete. In general, if the water-cement ratio is chosen correctly, a wide range in grading can be used without a major effect on strength.

Portland Cement Concrete - an overview

Portland cement concrete is a brittle material. The main reason for incorporating fibres into a cement matrix is to improve the cracking deformation characteristics, increasing not only the toughness, impact and tensile strength, but also eliminating temperature and shrinkage cracks.

SECTION 346 PORTLAND CEMENT CONCRETE

2019-4-3  PORTLAND CEMENT CONCRETE 346-1 Description. Use concrete composed of a mixture of portland cement, aggregate, water, and, where specified, admixtures, pozzolan and ground granulated blast furnace slag.

Can portland cement be mixed without sand or gravel ...

Aggregate is added to cement to give it strength. Without aggregate, you're basically going to have grey plaster with little inherent strength for both tension and compression. Even small aggregate, sand and pea gravel, will make a significant difference in the strength. Aggregate to cement proportions should be about 3 parts aggregate to 1 ...
