2) concrete quantity calculation for staircase and its formula. Genarally, Unit Weight of concrete is range from 2400 to 2500kg/m3 measured in Kilogram per cubic metre, and when it is measured in pound per cubic foot then it is range from 150 to 156lb/ft3. Unit Weight of concrete in kg.

Unit weight of cement is 1440Kg/m3 1 Kg = So unit weight of cement = 1440*/m3 = 14126N/m3 = /m3 Hope you got it..

 · Design values of concrete material properties according to EN199211 Unit weight γ. The unit weight of concrete γ is specified in EN199111 Annex plain unreinforced concrete γ = 24 kN/m concrete with normal percentage of reinforcement or prestressing steel γ = 25 kN/m 3.. Characteristic compressive strength f ck. The characteristic compressive strength f ck is the first .

Density is also called as unit weight of substance. It is represented by symbol called row ( p). Density represents the degree of compactness of material. If the material is of more density, it is more compacted material. Density is defined as the ratio of mass to volume. p = m/v Units = kg/m 3 or lb/ft 3 Conversion: 1 kg/m 3 = lb/ft 3.

 · CONCRETE WAQTC FOP AASHTO T 23 (17) T23_short_ Concrete 143 Pub. October 2017 to evenly distribute the concrete. For the 100 mm (4 in.) by 200 mm (8 in.) specimen, fill the mold in two layers. When filling the final layer, slightly overfill the mold. 2. Consolidate each layer with 25 strokes of the appropriate tamping rod, using the rounded

W = Unit Weight of fresh concrete as determined under above, lb/ft3 The volume of the batch in cubic yards (CY) is determined by dividing the number of cubic feet in the batch, S, by 27. 3. 3The cement content, "CC", lb/yd of concrete produced is calculated as follows:

In the below table we have tried to cover the unit weight of building materials which are most commonly used at the construction site. Material. Unit Weight. Water. 1000 Kg/ m3. Bricks (broken) 1420 Kg/ m3. Bricks (common) 1600 Kg/ m3.

 · Concrete has a tendency to provide a large diversity of unit weights. Not much differing from the RCC, the density of Portland Cement Concrete (PCC) is 2400kg/m3 or 24KN/m3 . The compactness of PCC defined by 24KN/m3 of density makes PCC be used as a foundation cement concrete .

How do you calculate weight of concrete in kg? A typical concrete mix weighs 150 lbs per cubic foot, 4,050 lbs per cubic yard, or 2,400 kg per cubic meter. The weight of concrete is determined by its density, which can vary based on the amount of aggregate, water, and air in the mix. Determine the Density of Concrete.

 · Unit Weight. Unit Weight of Construction Material is mass per volume and also is known as Specific Weight or Density. Density = M/V. Unit Weight of Construction Material is important to know for calculating the quantities of construction materials used on site. In Concrete Design Mix also we need to know the Unit weights of Cement, Aggregate ...

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.

 · Unit weight or density is used to quantify the weight per unit volume of an object. When it is expressed in the basic SI Unit of mass (kg/m 3), it is usually referred to as density, but when expressed in terms of weight (kN/m 3), it is usually referred to as unit weight.

 · Concrete slab thicknesses depend on the type of floor slab used in construction and the span of the slab. Generally, as the slab span increases, the concrete slab thickness and weight also increases. Useful page on loading in this link – Types of loads on structures. The differences between a one way slab and two slab can be found in this ...

Concrete that has a density lesser than 1920kg/m3 are classified as lightweight concrete. The utilization of lightweight aggregates in a concrete style can provide us lightweight aggregates. Aggregates are the vital part that contributes to the density of the concrete. The samples of lightweight aggregates are stone, perlites, and scoria.

 · W F = Weight of concrete per unit volume (air free) W A = Actual weight of concrete per unit volume. In the above case, the airfree weight would be: W F = 150 / ( ) W F = 160 lbs./cu. ft. In lieu of the measure, the bowl of the air meter may be used, since the test method prescribes a minimum sample size of 1/4 cubic foot.

the unit weight of a dry material (gdry) divided by the unit weight of water (gwater). Gs = gdry / gwater or gdry = Gs x gwater To determine the unit weight of a substance like cement, multiply the specific gravity of the cement by the unit weight of water. gcement = x lb/cu ft = lb/cu ft Bulk specific gravity of concrete materials
