Mar 01 1997018332The specification should also say if those proportions are by weight or volume If the proportions are based on weight use 4 pounds of coarse aggregate and 2 pounds of sand for every pound of cement To make the concrete though you still need to know the required watercement ratio

Answer manoj kumar bhola The unit weight of onecubic meter M20 concrete RCC 25000 NM3 2500 KGM3 25 KNM3 But may when this concrete made with standard gravel or crushed natural stone aggregateweight may depend upon the type of aggregate usedBelow M20 there will no concreting for RCC

The less weight of light weight concrete is due to the usage of fine and course lightweight aggregate When the complete aggregate is replaced with lightweight aggregate the weight decreases the concrete density of by approx 10 kilogram per cubic meter For Example 1 square foot of 15inch thick normal concrete weighs about 18 pounds

To withstand the weight of vehicle traffic choose a concrete with a strength of 4000 pounds per square inch for your driveway In areas with cold winters concrete mix should have a 6 percent

For M20 30 liters of water per 50kg cement Total amount of water required 30 x 4032 50 24192 litre 8064 bags of cement required for 1 cum of M20 grade concrete 630 kg of Sand required for 1 cum of M20 grade concrete 1260 kg of 20mm Aggregate is required for 1 cum of M20 grade concrete
4597
The reason being With constant research and development in the field of cement technology and its manufacturing process a M20 mix of 1153by volume would be too rich over engineered and uneconomical 75 bags of cement per cum and will ultimately result into a M30 concrete and above IS456 too have the minimum cement

Concrete mixes are defined in ascending numbers of 5 starting at 10 and show the compressive strength of the concrete after 28 days For instance C10 has the strength of 10 newtons C15 has the strength of 15 newtons C20 has 20 newtons strength and so on

To further expound upon my question as a general rule we use the following factor to determineestimate the weight of concrete for removal purposes 125lbs x thickness x size So in this example a 1ft x 1ft x 6quot thick slab area weighs approx 75lbs
3502
Normal Weight Concrete 145 pounds per cubic foot One square foot of 15 inch thick normal concrete weighs about 18 pounds The same segment created from lightweight concrete weighs approximately 145 pounds For comparison a square foot of 15 inch thick granite is 175 pounds
