To determine the number of cement bags needed for 20mm thick plaster, first calculate the total volume of plaster required. For example, if you need to cover 1 square meter, the volume would be 0.02 cubic meters (20mm = 0.02m). Assuming a typical mix ratio of 1:6 (cement to sand), you would need about 0.033 cubic meters of cement, which is approximately one 50 kg bag of cement per 1.5 square meters of plaster at that thickness. Therefore, for 1 square meter, you would need approximately 0.67 bags of cement.

There should not be any bricks in a bag of cement!
How many cubic meters in 1 cement bag of 50kgs
20 bag of cement equals 1 tone.

To estimate the amount of cement needed for plastering a 50 ft by 9 ft wall, first calculate the wall's area, which is 450 square feet (50 ft x 9 ft). The amount of cement required depends on the thickness of the plaster and the mix ratio. Typically, a standard plaster mix requires about 1 bag (94 lbs) of cement per 100 square feet for a thickness of about 1/2 inch. Therefore, you would need approximately 4.5 bags of cement to plaster the entire wall.
One standard bag of cement typically weighs 94 pounds, which is equivalent to approximately 0.047 tons. Therefore, 1 bag of cement is equal to 0.047 tons.
Depends how big the bag is
First assume the ratio of plaster is 1:4 (1 cement and 4 sand) now we have to plaster the wall having area of 100 sft assume the thickness of plaster 0.5 inches. first convert thickness in to feet so 0.5/12 = 0.0416 now to calculate the material use in cft so 100 sft x 0.0416 = 4.16 cft so we required 4.16 cft material to complete the plaster multiply it by dry factor 1.5 4.16 x 1.5 = 6.24 cft to calculate cement 6.24/(1+4) = 1.24 cft 1 cement bag volume 1.25 cft so calculate no of bags 1.24/1.25 = 1 bag to calculate sand (6.24/(1+4)) x 4 = 4.99 cft
