Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.

larger size aggregate. Cement is the most costly of the ingredients required to produce concrete. This implies that in order to minimize the costs of the concrete, the amount of cement used depends on the purpose for which the concrete is required. Concrete for load-bearing structures normally contains one part cement, two parts fine aggregate

May 17, 2017· Concrete Mix Design:-Concrete is a composite mixture which consists of Cement, Sand and Aggregate. Concrete mix design is the procedure for finding the right quantities of these materials to achieve the desired strength. Accurate concrete mix design makes concrete construction economical.

cement concrete. Therefore, the Standard Specifications limit the amount of deleterious constituents to a level consistent with the quality sought in the final product. Organic impurities are the only concern in fine aggregates. Section 904.02 places a restriction for fine aggregate for use in portland cement concrete and mortar.

a. Concrete Sand. Use only sand meeting the requirements of §703-07, Concrete Sand. b. Coarse Aggregate. Use only crushed stone, crushed gravel, or crushed slag meeting the requirements of §703-02, Coarse Aggregates in either one or a combination of size designations specified in Table 703-4, Sizes of Stone, Gravel, and Slag and graded according

The larger the stone the more empty volume/space between the stones that has to be filled with sand and cement and conversly the smaller the stone size then, by proportion, there will be less sand and stone. This will also vary with the concrete strength High (30 Mpa), Medium (25 Mpa) or Low (15 Mpa).

concrete. If all fine aggregate (sand) is used to make a one cubic metre batch, a large amount of cement-water paste is needed to coat and bond the particles. By adding coarse aggregate to the batch instead of a portion of the sand, the mixing water demand can be kept lower.
