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.
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?
cement is binding material while concreat is an homogeneous mixtur of cement sand and soil water etc.
