To calculate the quantity of cement required for 1 cubic meter of brick work with cement mortar (1:4), we need to first calculate the volume of brickwork. The formula for calculating the volume of brickwork is as follows:

Volume of Brickwork = Length x Breadth x Height

Assuming the dimensions of the brickwork to be 1 meter x 1 meter x 1 meter, we can calculate the volume as follows:

Volume of Brickwork = 1m x 1m x 1m
Volume of Brickwork = 1 cubic meter


The next step is to calculate the quantity of mortar required for the brickwork. The formula for calculating the quantity of mortar is as follows:

Quantity of Mortar = Volume of Brickwork / (1 + 4)

Assuming a mortar mix ratio of 1:4, we can calculate the quantity of mortar required as follows:

Quantity of Mortar = 1 cubic meter / (1 + 4)
Quantity of Mortar = 0.2 cubic meters


The final step is to calculate the quantity of cement required for the mortar. The formula for calculating the quantity of cement is as follows:

Quantity of Cement = (Cement Ratio / Sum of Ratio) x Quantity of Mortar

Assuming a cement mix ratio of 1:4, we can calculate the quantity of cement required as follows:

Quantity of Cement = (1 / (1+4)) x 0.2 cubic meters
Quantity of Cement = 0.04 cubic meters
Quantity of Cement = 1.421 bags (Assuming a bag of cement weighs 50 kg)


Therefore, the quantity of cement required for 1 cubic meter of brick work with cement mortar (1:4) is 1.421 bags or 71.05 kg.
