Steps:-. First calculate the volume of concrete with the help of the length, width and height of the structure. Then multiply the volume by their density to get the total weight of concrete. Let, Total volume of concrete be 5 m 3. Calculate the weight of concrete. The, Weight of concrete = Volume x Density = 5 x 2400 = 12000 Kg.
The unit weight is determined by the formula below. Subtract the weight of the measuring base from the combined weight of the measuring base and the concrete it contains. Next, divide this weight (in pounds) by the volume of the measuring base (cubic feet) to obtain the density expressed as lb/ft 3:

Nowadays, we typically use a 1:2:4 mix ratio when building a reinforced concrete single-story house. As a nickname, we can call this mix M15 grade, which comes from its corresponding 15 MPa compressive strength.If we want to build a 2-story house, we would need a stronger mix like the M20 grade mix, which follows a 1:1.5:3 mix ratio.. …

Unit Weight. Unit weight and strength are the two properties generally sought from lightweight concrete. In concrete, it is generally preferred to have the highest possible strength/ unit weight ratio with the lowest cost of concrete. The air-dried unit weight of concrete is limited to a maximum of 18.40 kN/m3.
Specific gravity is the weight of the cement divided by the weight of an equal volume of water. If you're using portland cement, 1 cubic foot loose volume weights 94 pounds and has a specific gravity of 3.15. ... 94 pounds, by the specific gravity times the unit weight of water (62.4 pounds per cubic foot) gives a volume of cement of 0.478 ...
ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates. ... ("Unit Weight") and Voids in Aggregate . C142/C142M-17(2023 ...
Cement, clinker weighs 1 415 kg/m³ (88.33556 lb/ft³) [ weight to volume | volume to weight | price | density] Cement, mortar weighs 2 162 kg/m³ (134.96925 lb/ft³) [ weight to volume …
How to calculate unit weight of concrete. Significance and Use of ASTM C138. Knowing the unit weight of a sample of concrete can help you figure out if your lightweight concrete is really lightweight and is …
