For testing, British Standard (BS 812) has specified the degree of compaction. (2011). It is the ratio of the oven dried density of the aggregate to the density of the gas free distilled water at a standard temperature (i.e. How to test aggregate for bulk density and voids. Is:2386(PartIll)-1963 2.2 Method I - Aggregate Larger than 10 mm 2.2.1 4 b! a b b x (100-a)/100 remark : test report for compacted density of mix aggregate astm d-1559 italian-thai name : _____ date : _____ name : _____ The compacted bulk density in kg/m 3 shall be calculated by the following equation: The research investigated four common techniques used to measuring the bulk density … According to the graph void content vs. fine aggregate content and the results, the optimum fine aggregate content required to obtain minimum void content and maximum bulk density is 40% fine aggregate and 60% coarse aggregate. REPORT 7.1 Report specific gravity results to the nearest 0.001, and indicate the type of specific gravity, whether bulk (O.D. In this experiment, it has clearly shown that compacted aggregate which has bigger unit weight (bulk density) provides better cement strength. The main problem in determining the bulk density of rock core is obtaining an accurate estimate of the rock core’s total volume. the bulk density of rock core samples typically encountered in the mining industry. of mix of specimen density of mix agg. specimen % ac by bulk density compacted average compacted no. (1993) Concrete Structure, Properties, and Materials, … 7.3 If the specific gravity and absorption values were determined without first drying

It is the ratio of the saturated surface dry density of the aggregate to the density of the gas free distilled water at a standard temperature (i.e. These are; Loose ( Un-compacted) Compacted; The test will be carried out by using metal cylinder having prescribed depth and diameter and the bulk density is to … Retrieved March 13, 2016 from -to-test-aggregate-for-bulk-density-and-voids/ Mehta and Monteiro. 4 o C). 10.0 REFERENCES Anonymous. ), bulk (SSD), or apparent. 7.2 Report the absorption result to the nearest 0.01%. density of mix g/cc. wt. 4 4 4 f > g> Apparatus - The apparatus shall consist of the following: Balance -A balance or scale of capacity not less than 3 kg, readable and accurate to O-5 g and of such a type and shape as If a statement is like: A coarse aggregates with higher bulk density, then it means few of the voids can be filled by using fine aggregates and cement. 4 o C).
