• Confirm receipt and understanding of the message to avoid miscommunication

The cement consumption in PCC 1:4:8 mix is 3.6 bags.

• Cement consumption is calculated based on the volume of concrete mix and the ratio of cement in the mix.

• For PCC 1:4:8 mix, the ratio means 1 part cement, 4 parts sand, and 8 parts aggregate.

• Therefore, in a PCC 1:4:8 mix, the cement consumption is 3.6 bags.

The consumption of bags of cement in a 1:1.5:3 concrete mix is 8 bags.

• In a 1:1.5:3 concrete mix, the ratio represents the proportion of cement, sand, and aggregate respectively.

• For every 1 part of cement, there are 1.5 parts of sand and 3 parts of aggregate.

• Therefore, in a 1:1.5:3 mix, the total parts would be 1+1.5+3 = 5.5 parts.

• To calculate the number of bags of cement needed, divide the total parts by the part of cement (1) and multiply by the total volume of concrete need...read more
