The Standard Specification for Concrete Aggregate, ASTM C 33 sets no limits on the amount of pyrite that can be allowed. We do not know of any standard acceptance test for aggregate other than ASTM C 294.

For the same strength or workability, concrete with large size aggregate will require lesser quantity of cement than concrete with a smaller size aggregate. In a mass concrete work the use of larger size aggregate will be useful due to the lesser consumption of cement.

Iron and steel slag products: Concrete aggregate. ... This has resulted in a rapid increase in the amount of concrete slag aggregates that are sold.

Step 5: Proportion of Volume of Coarse Aggregate and Fine aggregate Content. From Table 3 of IS 10262 2009, Volume of coarse aggregate corresponding to 20 mm size and fine aggregate (Zone I) = Note 1: In the present case watercement ratio is hSo there will be no change in coarse aggregate volume .

Aggregate Absorption: Aggregate can absorb water up to 2 % by weight when in bone dry state, however, in some cases the aggregate absorption can be as high as 5%. Aggregate absorption is used for applying a correction factor for aggregates in dry condition and determining water demand of concrete in saturated surface dry condition.

For adequate consolidation of concrete, the desirable. amount of air, water, cement, and fine aggregate (that is, the mortar fraction) should be about 50% to 65% by. absolute volume (45% to 60% by mass).

Influence of the amount of recycled coarse aggregate in concrete design and durability properties

The fine aggregate can generally contain less material passing 300 um and 150 um sieve because of the higher cement content. Proportionally, the amount of fine aggregate should also be somewhat less than that used for normal strength concrete. Shape:

Definition of aggregate: General: Collective amount, sum, or mass arrivedat by adding or putting together all components, elements, or parts of an assemblage or group, without implying that the resulting total is whole ...

Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and harden into the durable material with which we are all familiar.

The final properties of the concrete will depend on the cement characteristics, the type and amount of aggregate, the watercement ratio, and the completeness of the reaction subject to time, humidity, and temperature. Examples of classes of concrete aggregate are shown below. Types of Aggregates
