High strength concrete properties, admixture, and mix .

Concrete is a mixture of cement, water, coarse and fine aggregates with or without chemical and mineral admixtures. As aggregate covers 75 percent of the volume of concrete, for HSC, high-strength well-graded aggregate is essential. The presence of different sizes of aggregate (well-graded) in appropriate proportions is important to reduce void.

Crushing strength of aggregate - Answers

Aggregate is the gravel or stone in the concrete. It is what gives concrete it's strength. Think of the aggregate as the bricks of a wall and the concrete and sand as the mortar.

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON .

smaller sized coarse aggregate produces higher strengths for a given water-to-cement ratio. In fact, it is generally agreed that, although larger coarse aggregates can be used to make high-strength concrete, it is easier to do so with coarse aggregates below 12.5 mm (Y, in.) (ACI 363-95).
