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

All Aggregate. It is the aggregate composed of both fe aggregate and coarse aggregate. Accordg to size All--aggregate is described as all--aggregates of its nomal size, i.e. 40mm, 20mm etc. For example, all aggregate of nomal size of 20mm means an aggregate most of which passes through 20 mm IS sieve and contas fe aggregates also.

aggregate size numbers. Fe aggregate or sand has only one range of particle sizes for general construction and highway work. The gradg and gradg limits are usually expressed as the percentage of material passg each sieve. Fig. 5-6 shows these limits for fe aggregate and for one size of coarse aggregate.

Total Aggregate by cement ratio (A/C) decreases with crease grade of concrete. For example, M20 grade of aggregate will have a higher A/C ratio than of M30; Higher the A/C ratio leaner the concrete mix, as cement content is lower. 2.A/C ratio may be fe tuned to get a concrete mix more workable.

2. Fe aggregate: Generally speakg it is sand, and can be divided to coarse sand, medium sand, fe sand. For pumpg concrete configuration it requires the medium sand, that is, feness modulus of 2.5 is the most appropriate. The fluence of fe aggregate (sand) on concrete mix is greater than that of coarse aggregate.
