QUANTITIES OF CONCRETE MASONRY AND MORTAR

This table calculates theoretical quantities only. On-site management and monitoring of waste has a large influence on the final quantity of materials that would actually be used.
EXAMPLE:
A 190mm boundary wall, 80m long and 2m high using MA190 blocks, with class II mortar is to be built.

Area of wall: 80m x 2m = 160m²

Number of blocks / m² = 12.5

Total numnber of blocks required = 12.5 x 160 = 2000

Mortar required = 160m² / 100 x 1.43 = 2.29m³ OR 2 x 1.14 = 2.28m³

Plaster required = 2 x 0.80 = 1.60m³

Combined mortar and plaster = 3.88m³
