Mar 17, 2018· Density of concrete depends on the density of materials used, water content while placing, voids in the mix, how good your placing and compaction is, etc. Normally, this is between 2.35 to 2.5 tons per cum, unless light weight, air entrained, etc....

The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of 1.13 (1130 kilograms/cubic meter).

Specific weight Wikipedia Chinese. 201934&ensp·&enspThe specific weight (also known as the unit weight) is the weight per unit volume of a material. The symbol of specific weight is γ (the Greek letter Gamma ). A commonly used value is the specific weight of water on Earth at 4°C, which is 9.807 kN/m 3 or 62.43 lbf /ft 3 .

If the specific gravity of cement is greater than 3.19 then, the cement is either not minced finely as per the industry standard or it has more moisture content which will affect the mix and bonding. This is why you find lots of chunks while mixing old stock cement for concrete.

Depending on the varying value of specific gravities, equal volume of different types of sand would weigh differently. For example, wet sand weighs approximately 120 lb. per cubic foot and has a specific gravity of 1.92, while dry sand weighs about 100 lb. per cubic foot and has a specific gravity of 1.60.

If the specific gravity of cement is greater than 3.19 then, the cement is either not minced finely as per the industry standard or it has more moisture content which will affect the mix and bonding. This is why you find lots of chunks while mixing old stock cement for concrete.

Take a few minutes to learn about the three most commonly used sand types; Concrete Sand vs. Mason Sand vs. White Sand. Concrete Sand. Concrete sand is and aggregate sand usually composed of either gneiss, trap rock, limestone or granite. This specific type of sand is normally crushed at the quarry and then washed and screened for quality.

The proportions of cement, sand, coarse aggregate and water plays an important role in determining the fresh and hardended properties of concrete. So care should be taken while calculating the amount of Cement, Sand and Aggregate required for 1 Cubic meter of Concrete. Method-1: DLBD method to determine material requirement for 1 Cum concrete The DLBD (Dry

By Adam D. Neuwald. Two of the most commonly specified requirements for concrete used in the manufactured concrete products industry are the design compressive strength (f’ c) and the maximum water-to-cement ratio (w/c).These two values are inversely related, which means that as the water-to-cement ratio increases, the compressive strength decreases.

The volume of concrete (L x B x D) = 5 x 2 x 0.1 = 1 Cum. Volume of Concrete = 1 Cum. We find out the volume of concrete in wet condition 1m 3 (After the consolidation of Cement+sand+water). So in dry conditions, we have to add 30 to 35% sand bulkage and add 20% for wastage.
