How do you find the mass of coarse aggregate?
The quantities of materials for 1 m3 of concrete production can be calculated as follows: The weight of cement required = 7.29 x 50 = 364.5 kg. Weight of fine aggregate (sand) = 1.5 x 364.5 = 546.75 kg. Weight of coarse aggregate = 3 x 364.5 = 1093.5 kg.
How do you calculate aggregate weight?
Manual Calculator
- Multiply the length of the area by the width of the area = Square Feet.
- Multiply Square Feet by the Depth* = Cubic Feet.
- Divide Cubic Feet by 27 = Cubic Yards.
- Multiply Cubic Yards by 1.5 = Tons Needed.
What is bulk density of coarse aggregate?
In this definition, the volume is that contains both the aggregates and the voids between aggregates particles. The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m3 (75-110 lb/ft3).
How do you calculate mass of concrete?
If you know the density, the mass per unit volume of a material (such as concrete), and the volume of the material, you can multiply the density times volume to determine the mass, and, from there, the weight.
What is the standard size of coarse aggregate?
– Coarse aggregates are particulates that are greater than 4.75mm. The usual range employed is between 9.5mm and 37.5mm in diameter. – Fine aggregates are usually sand or crushed stone that are less than 9.55mm in diameter. Typically the most common size of aggregate used in construction is 20mm.
What is unit weight of coarse aggregate?
Density of coarse aggregate 20mm and 40mm ranging between 1200 – 1450 kg/m3 (75 -90 lb/ft3) and density of fine aggregate 10mm and 12mm ranging between 1600 – 1750 kg/m3 (100 – 109 lb/ft3).
Why is bulk density of aggregate determined?
The bulk density measures the volume that the graded aggregate will occupy in concrete, including the solid aggregate particles and the voids between them. Since the weight of the aggregate is dependent on the moisture content of the aggregate, a constant moisture content is required.
