This test method covers the determination of relative density (specific gravity) and the absorption of fine aggregate. The relative density (specific gravity), a dimensionless quality, is expressed as oven-dry (OD), saturated-surface-dry (SSD), or apparent relative density (specific gravity). The OD relative density is determined after drying the aggregate.
thanks for ask bro… Coarse Aggregate in general should consist of natural occurring stones (crushed, uncrushed or broken), riverbed single or pit gravel. It should be hard, strong, dense, durable, and clean. It must be free from veins, adherent co...

An example provided in the ACI 211 standard states that, "For a fine aggregate having a fineness modulus of 2.8 and a 37.5mm nominal maximum size of coarse aggregate, the table indicates that 0.71m3 of coarse aggregate, on a dry-rodded basis, may be used in each cubic meter of concrete. The required dry mass is, therefore, 0.71 x 1600 = 1,136kg."
Sieve sizes commonly used for concrete aggregates are detailed in Table 1, and various physical properties of normalweight aggregates, with typical range values, are shown in Table 2. Coarse and fine aggregates are generally sieved separately. That portion of an aggregate passing the 4.75 mm (No. 4)
1. Scope. 1.1 This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.

the laboratory density figures to compensate for the effect of the oversize particles. The formula that has been used in ia assumes that the minus No. 4 material is able to maintain its maximum laboratory density constant, much as though this material were a fluid, and that coarse aggregate particles merely displace a portion of the fine 22
b) Calculate the unit weight and percentage of voids in coarse and fine aggregates. c) Interpret how the bulk density affects concrete mix design. 7.3. Objectives of the Experiment The objective of this experiment is to determine the bulk density of aggregates (coarse and fine) and percentage of voids between aggregates on a dry basis. 7.4.
