· Approximate Weights of Various Construction Material Per Cubic Yard Most of Harmony Sand & Gravel’s products will weight approximately 2,840 pounds per cubic yard or about 1.42 tons per cubic yard. For estimating purposes, most Contractor’s consider the yield to be 3,000 pounds per cubic yard or 1.5 tons per cubic yard.

The approximate bulk density of sand that is commonly used in normal-weight concrete is between 1520- 1680 kg/m3 (95-105 lb/ft 3) Here, Standard test method for determining the bulk density of sand is given in ASTM C 29 (AASHTO T 19).

Cement density:- generally density of cement is around 1440kg/m3 or it is measured in other unit- their density is 1.440 in g/cm3, 94 in lb/ft3 and 14.40 in kn/m3. The cement mixed with fine aggregate produces cement mortar for masonry, or with sand and gravel produces concrete. Ans. 1440 kg/m3 is density of cement.

In the above definition, the volume contains both aggregates along with voids between aggregate particles. The approximate value of bulk density for aggregate usually used for normal-weight concrete varies between 1200-1750 Kg/m3 or 75 to 110 lb/ft3. Relative Density or Specific Gravity of Aggregate

Density of aggregate is = 1550 Kg/Cu.m. Weight of aggregate = 0.947 X 1550 = 1467.85 Kg So we finally find the quantity of cement, sand, aggregates, in M 7.5 grade concrete is 1) cement = 3.42 Bags

· The unit weight if different civil engineering materials including brick, cement, concrete and aggregate are as follows : Material Unit Weight. Water 1000 Kg/ m3. Bricks (broken) 1420 Kg/ m3. Bricks(common) 1600 Kg/ m3. Cement(ordinary) 1440 Kg/ m3. Cement (rapid hardening) 1250 Kg/ m3. Cement Mortar 2000 Kg/ m3. Cement Concrete (Plain) 2400 Kg/ m3

· THEORETICAL WEIGHT (kg/m 3) 1. Cement: 1440 kg/m 3: 2. Steel: 7850 kg/m 3: 3. Sand (a) Dry: 1600 kg/m 3 (b) River: 1760 to 2000 kg/m 3: 4. Stone (Basalt) 2850 to 2960 kg/m 3: 5. Cement Concrete (Plain) 2400 kg/m 3: 6. Cement Concrete (Reinforced) 2500 kg/m 3: 7. Water: 1000 kg/m 3: 8. Bricks: 1600 to 1920 kg/m 3: 9. Brick Masonry: 1920 kg/m 3 .

In General we use 1:2:4 mix ratio by volume, in which one part is cement 2 part is sand and 4 part is aggregate and water cement ratio is 0.4. In general, weight of concrete per m3 is 2400kg, if steel is provided in concrete, then, for 1 cubic metre, the weight of reinforced concrete or rcc is generally taken as 2500kg, and however, if steel is .

The cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. First, density is the ratio of mass to volume. So it can be indicated in terms of kg / m 3 , which is 1440kg / m 3 for cement .

The cement mixed with fine aggregate to have mortar for plaster and masonry, and with sand and coarse aggregate to give concrete. As I said, earlier density is the material’s mass per unit volume. Since we measure mass in kg or lb and volume in litre or cubic meter or cubic feet, hence density is stated in Kg/m 3 or lb/ft 3 .

Near about 35% volume of the concrete is comprised of sand. For concrete to be of good quality it should be produced by careful mixing of cement, fine and coarse aggregates, water, and admixtures as needed in order to obtain optimum quality and economy.. Natural sand i.e. locally available River sand having a bulk density of 1.71 kg/m3 was used for the construction (specific gravity is 2.65).

· Approximate Weights of Various Construction Material Per Cubic Yard. Most gravel products will weight approximately 2,840 pounds per cubic yard or about 1.42 tons per cubic yard. For most estimating purposes, consider the yield to be 3,000 pounds per cubic yard or …

Specific Weight or Unit weight of Sand. Unit weight or Specific Weight of sand is calculated by the product of the density of sand and the standard gravity of sand. According to the US customary measurement system, dry weighs 1.631 gram per cubic centimeter, this density is equal to 101.8 pounds per cubic foot [lb/ft³].

· Now we start calculation for find Cement, Sand and Aggregate quality in 1 cubic meter concrete. CALCULATION FOR CEMENT QUANTITY; Cement= (1/5.5) x 1.54 = 0.28 m 3 ∴ 1 is a part of cement, 5.5 is sum of ratio Density of Cement is 1440/m 3 = 0.28 x 1440 = 403.2 kg We know each bag of cement is 50 kg

Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, 0.42 m 3 of sand and 0.83 m 3 of stone aggregate.

By weight a ton of cement and a ton of sand weigh the same amount, but by volume in an identical bags/containers of same capacity, we will get more cement (heavier) than sand i.e. 1 cubic meter of cement will be heavier to 1 cum of sand, this is because of cement mineralogical composition (composition of its raw materials) differ than that of natural sand.

Unit weight of steel 7850 kg/m3, cement 1440 kg/m3, sand (dry) 1540 to 1600 Kg/ m3, brick 1600 Kg/ m3, Aggregates 1750 kg/m3, bitumen 1040 kg/m3
