Determine the CHB thickness used for your wall: Concrete hollow blocks (CHB) vary in sizes. Local hardware stores usually have 3 commercially-available CHBs that vary in thickness – 4"(10cm), 6"(15cm) and 8"(20cm). 4"(10cm) thick CHBs are usually used for interior walls while 6"(15cm) and 8"(20cm) thick CHBs are usually used for exterior walls.

An excessively high water-cement ratio can result in weaker concrete with lower strength and increased susceptibility to cracks and shrinkage. In the case of C40 concrete, a water-cement ratio of 0.4 or lower is generally recommended to achieve the desired strength. This means that for every 1 kg of cement, 0.4 kg of water is used.
