A house, once built, will be a companion for life. Hence, any decision about the construction of a house lasts a lifetime and cannot be reversed. Therefore, utmost care must be taken when choosing materials to build the home of dreams. One of the most critical elements of constructing a sturdy, long-lasting abode is the choice of bricks used in construction. Good quality bricks, once chosen, will be able to withstand any harsh condition and remain unscathed. Hence, bricks must be selected only after studying all the specifications carefully.
The hardness of the brick
The first factor in choosing quality bricks is brick hardness. The higher the brick's hardness, the higher the structural integrity of the home being built. An effective way of measuring the brick's hardness is to scratch it with a sharp object like a knife. If the scratch is minimal or non-existent, the hardness is perfect. Another method is to strike two bricks together with one brick in each hand. If the brick breaks, then the bricks are not hard enough. A good quality brick is homogeneous and compact without any lumps.
Water absorption rate
Bricks are going to have to deal with rains and showers from time to time. Hence, bricks must be water absorbent so that their bonding with the cement is unaffected. A good way to measure water absorption by the bricks is to immerse a brick in water for 24 hours. If the brick's weight has increased by more than 24 percent, it has absorbed too much water, and it is unsuitable for use.
Brick efflorescence phenomenon
Efflorescence is the phenomenon in which harmful salts are deposited on the brick surface due to exposure to air. These deposits can be seen as white patches on the surface of the brick. When there is heavy efflorescence, the bricks are unsuitable for construction because they dissolve when they contact water. Efflorescence tests are conducted to check for the area of deposits. If there is efflorescence is more than 20 percent of the brick’s surface, the brick is unsuitable for use.
Uniformity in color and shape
The color and shape of the bricks must be consistent throughout. A good quality brick is a well-burnt brick that has a rich red or copper color. A lighter color implies that the brick is under-burnt, and such bricks lose their shape over time. Bricks must also be uniform in dimensions, but a tolerance level of 3 centimeters is allowed.
