specific gravity of material x unit weight of water For example, the specific gravity of a dry coarse aggregate (Gs) is 2.65. The unit weight of water is 62.4-lb/cu ft. The absolute volume of a 90-lb sample of the aggregate is: Absolute Volume = 90 lb / (2.65 x 62.4 lb/cu ft) = 0.544 cu ft.
In this study, five different design unit weights of the coarse aggregate selected to evaluate aggregate packing characteristics.RUW ranging from 80 to 90%. 2.1.3. Fibers Fibers are being used in SMA as a stabilizing agent and to reduce the drain down significantly .Various fibers have been used in various studies showing very good results.
Weight Conversion Tables. How may tonnes in a cubic metre - This one of the many questions we are asked Dry sand fine 1.28 tonnes per cubic metre Dry sand coarse 1.6 tonnes per cubic metre Topsoil (some moisture) 1.44 tonnes per cubic metre Ballast 1.76 tonnes per cubic metre Gravel MOT Type 1 scalpings 1.92 tonnes per cubic metre
Reinforced cement concrete or RCC calculator can be used to calculate M15, M20 and M25 mix ratio of cement, sand and jelly. At materialtree.com, you can also …
As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft. Note, kg/cu.m divided by 16.02 = lbs/cu.ft
A normal weight concrete weighs 2400 kg per cubic meter or 145 lbs per cubic foot (3915 lbs per cubic yard). The unit weight of concrete (density) varies depending on the amount and density of the aggregate, the amount of entrained air (and entrapped air), and the water and cement content.
Material estimation include sand, cement, coarse aggregate and steel for a particular mix design. Let us consider a mix design of 1:1.5:3 for our estimation practice. The dry volume of total materials required is considered as 1.54 times the wet volume of concrete, due to voids present in sand and aggregates …
The maximum unit weight of a blend of two aggregates is about 40% fine aggregate by weight. Therefore, this is the most economical concrete aggregate since it will require the least amount of cement. Durability of Aggregates . Aggregates makeup the largest part of concrete mixes and are responsible for the durability of the mix.

A hollow unit is that unit which has core void area greater than 25% of the gross ... The aggregate consist of 60% fine aggregate (sand or stone dust) 40% course aggregate (6 to 12 mm size) ... Water Absorption:- <10 to 15% by weight. ADVANTAGES
The Unit weight or bulk density of aggregate is the mass or weight of the aggregate required to fill a container of a specified unit volume. The approximate unit weight of aggregate that is commonly used in normal concrete work is between 1200-1750 kg/m 3 (75-110 lb/ft 3 ).
5. TEST FOR SPECIFIC GRAVITY OF AGGREGATE The specific gravity of a substance is the ratio of the unit weight of the substance to the unit weight of water. A representative aggregate sample in SSD condition is obtained by quartering and the following weights are used in the tests for the various sizes of aggregates. Less than 4.75 mm : 500 to ...
• The aggregates are then placed in an oven at a temperature of 100 to 110 degree C for 24 hrs. • After 24 hrs, aggregates are removed and cooled in air tight container and weighed. • Water Absorption = (W1/W2) x 100 – Where, W1 is weight in gm of the surface dry aggregate. – W2 is weight in gm of oven dried aggregate.

1 SPECIFIC GRAVITY AND ABSORPTION OF FINE AGGREGATES AASHTO T 84 GLOSSARY Absorption: The increase in mass due to water in the pores of the material. Bulk Specific Gravity (also known as Bulk Dry Specific Gravity): The ratio of the weight in air of a unit volume of aggregate at a stated temperature to the weight in air of an equal volume
Aggregates. Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the ...
The ACI Method of Mix Design • Knowing the values of maximum size of coarse aggregates and fineness modulus (FM) of fine aggregate, bulk volume of dry rodded aggregate per unit volume of concrete is selected from table 9.14 • Dry Bulk of Coarse Aggregate per unit Volume of Concrete as Given by ACI 106.
To coat particles and maintain the cohesiveness of concrete mix smaller maximum size of coarse aggregate would require greater fine aggregate content. 40mm down aggregate would have lower water and cement ratio for the same workability thus higher strength when compared to 20mm down aggregate and advantage of the higher maximum size of these ...
