The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m 3 (75-110 lb/ft 3). Here, the Standard test method for determining the bulk density of aggregates is given in ASTM C 29 (AASHTO T 19). [2] Relative Density of Aggregate [1]

Density of Coarse Aggregate Aggregate which occupy nearly 80 to 85 % volume of concrete are most important part of the concrete or RCC. However, it is well recognize that physical, chemical and thermal properties of aggregate substantially influence the properties and performance of concrete.

In general, the higher the packing density of the aggregate, the smaller will be The values of bulk density of the coarse aggregates (20mm and 12.5mm size) IS 2386 Know More.

The fine aggregate (mineral filler) is used to fill in the voids between the coarse particles, which increases the density of the asphalt concrete and provides load transfer between the larger particles. The asphalt binder is typically 5-6% of the mixture, and serves to bind the aggregates together.

The aggregate exclusively passing through 12.5mm sieve size and retained on 10mm sieve is selected. The aggregates were tested for their physical requirements such as gradation, fineness modulus, specific gravity and bulk density in accordance with IS: 2386-1963. The individual aggregates were mixed to induce the required combined grading. The

Keep in mind that density is a relative term, compared to a target density of either lab compacted mix, a maximum theoretical density, or a control strip density. Procedures for using the three methods are spelled out on Page 7-17 to 7-21 of the new MS-22 and Page 241 of the old MS-22.

Dense-graded aggregate has about 35 sq. ft. of surface area per pound, or 196,000 sq. ft/6000 lb. batch; 400 pounds of asphalt is about 48 gallons. The mixing process has to take 48 gallons of asphalt and paint about 3.8 football fields. When the aggregate particles are coated, it’s mixed.
