BRICKS AND BLOCKS

Metric bricks are a little smaller than the old imperial one.   New bricks can be bonded into old brickwork by slightly increasing the mortar bed joint.

There are a variety of sizes available and they differ from country to country. Brick sizes have remained fairly constant over the years although, in the UK, the depth used to be less (about 2 ins/51mm) whereas modern bricks are about 2.5 ins./64mm.

American bricks are about 8 4 2.25 inches (203 102 57 mm);  South African 8.75 x 4 x 3 inches (222 x 106 x 73mm) and in Australia they are 9 x 4.33 x 3 inches (230 x 110 x 76mm).

 

Comparisons of metric and imperial bricks are as follows:-

BRICK QUANTITIES

AREA QUANTITY MORTAR
1 Sq. Metre   60 bricks 0.02 cubic metres
2 Sq. Metres 120 bricks 0.05 cubic metres
5 Sq. Metres 300 bricks 0.12 cubic metres
10 Sq. Metres 600 bricks 0.24 cubic metres

Building blocks in a size which co-ordinates with bricks are also available.  These blocks are equivalent to two brick lengths and three brick heights (i.e. a total of six bricks).

1 Sq. Metre 10 blocks 0.01 cubic metres
2 Sq. Metres 21 blocks 0.02 cubic metres
5 Sq. Metres 53 blocks 0.05 cubic metres
10 Sq. Metres 106 blocks 0.10 cubic metres

 

MORTAR and CONCRETE

1 kg. of dry mortar mix (i.e.1 part cement to 5 parts dry building sand) when mixed with water will lay approximately one brick.

Doug Reay

It is recommended that for brickwork below ground level the ratio should be reduced to 1 part cement to 4 parts soft dry builders' sand.

2240 Kgs. all-in-ballast will make approximately 1 cubic metre concrete.
