What is weight batching of concrete?
the materials of the concrete are divided into based upon their unit weights. The specific weights are to be known for this . it is different from volume batching
How do you calculate the wastage in concrete?
You need to calculate the total volume of the space that the concrete has to fill. if you're doing a slab 4" thick a cu. yd. will cover 81 sq. ft. Take the total area and divide by 81 to get the number of yard needed.
Wet concrete weight?
weight of hardened concrete + 100 kgf/m3
What is weight of concrete per Cum?
Weight of concrete is 155 lbs/cft or 70.308 kg/cum
What is the weight of one square meter of a reinforced concrete slab?
The weight can only be determined if the exact weight of the reinforcement, as well as the exact displacement of the reinforcing is known. Thus the weight should be 1 sq meter x thickness of the concrete minus the exact displacement of the reinforcing, plus the weight of the reinforcing. The weight per cubic meter of concrete is 2450 kg.
Why is it that weight batching of aggregate is more preferable to volume batching of aggregate?
why is batching of aggregate by weight is preferable than batching by volume

Effects of bulking of fine aggregate on the performance of concrete?
bulking of fine aggregate increases its volume. hence the mass for a given volume is less, which leads to richer mix than required. therefore batching of fine aggregate must be done by weight and not by volume.
How many 112 pound bags of cement would you need to build an average size 3 bedroom bunglow?
Based on a 50 c.y. foundation with a minimal 2500psi concrete, manual batching would require approx 214.28 bags of type-II/V. Impossible to be exact not knowing the end result vol. Concrete is batched by weight to achieve a desired volume of material.
How much concrete was used to build the millau bridge?
The volume of concrete used to build the Millau bridge is 85,000 m3 (cubic meters). The weight of this volume of concrete is 206,000 metric tons.
How do you calculate the weight of a pre-cast concrete tilt-wall panel?
To calculate the weight of a pre-cast concrete tilt-wall panel, you would need to know the volume of the panel and the density of concrete typically used in such panels. You can then multiply the volume by the density to determine the weight. The formula would be weight = volume x density.
A box shaped piece of concrete measures 3ft by 2ft by 0.5ft what is it weight?
The weight density for concrete is 156 lb/ft3 and the volume of the box is 3 ft3 if you multiply both number you can find the weight. Total weight is 468 lb.
What is the difference between a normal weight concrete and a lightweight concrete by volume?
The main difference between normal weight concrete and lightweight concrete by volume is the density of the aggregate used in the mix. Normal weight concrete contains aggregate with a density around 2400 kg/m3, while lightweight concrete uses lightweight aggregate such as expanded clay, shale, or shale to reduce the overall density of the concrete. The reduced density of lightweight concrete makes it more suitable for applications where weight is a concern, such as in construction of high-rise buildings or for insulation purposes.
How do you calculate the self-weight of a column?
To calculate the self-weight of a column, first determine the volume of the column by multiplying its cross-sectional area by its height. Then multiply the volume by the density of the material the column is made of (typically concrete or steel) to obtain the self-weight.

What weighs more a pound of feathers or a pound of concrete?
They both weigh the same, one pound. The difference lies in the volume or amount of feathers and concrete needed to reach that weight. Feathers are much less dense than concrete, so a pound of feathers will take up much more space than a pound of concrete.
Wet concrete weight?
weight of hardened concrete + 100 kgf/m3
