Get PriceMost aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m 3 (150-181 lb/ft 3). Here, for coarse aggregates, the standard test method has been explained in ASTM C 127(AASHTO) and for fine aggregates, the standard test method has been explained in ASTM C 128 (AASHTO). [3]

Get Price30.10.2020· 1.18 mm (No. 16) The grading of coarse aggregates is done for 13 size numbers Fine-Aggregate Grading. Fine-aggregate grading depends on the type of work, the richness of mix, and the maximum size of coarse aggregate ; Fine-aggregate grading within the limits of ASTM C 33 is generally satisfactory for most concretes. The ASTM C 33 limits with respect to sieve size are as follows: Sieve
Get PriceTo determine the 'ten percent fine value' the aggregate sample is prepared in the same manner as in the case of determining the aggregate crushing value. A prepared aggregate sample (weighing 'A') is placed in the test apparatus and the load is applied uniformly through a plunger at uniform rate so as to cause total penetrations in 10 minutes
Get Pricetion values of coarse and fine aggregates are found in litera- resistance of fine aggregates depends on the moisture content of the aggregates. They used fine aggregate (pit sand, crushed sand, and slag sands) with particle size between No. 4 and No. 200 sieves. However, investigations in the literature have not to date focused on characterization of very fine particles under 1 mm (0.04 in
