The white surface salts that disfigure new brickwork are derived from the mortar the bricklayer joined the bricks with. These salts are moved through the brick by capillary action. Sometimes, bricks are wetted before use to minimise this effect.
The efflorescence as it is known, will gradually disappear with weathering.
The addition of long-chain fattty acids (water extenders) to the mortar will help minimize the effect.

Why is a brick heavy when its out of water?
A brick is heavy because it is made from dense materials like clay or concrete, which have high mass and weight. The absence of water in a brick does not significantly affect its weight because the dry materials themselves are still heavy.
What is the water absorption rate in bricks?
The water absorption rate in bricks typically ranges from 5% to 20%, depending on the type of brick and its manufacturing process. This rate indicates how much water a brick can absorb relative to its dry weight. Higher absorption rates can affect the durability and thermal performance of the bricks. It's important to choose bricks with appropriate absorption rates for specific construction needs.
Does breezeblocks absorb water?
Breezeblocks, also known as concrete masonry units (CMUs), can absorb some water due to their porous nature. However, the extent of water absorption depends on the specific type of breezeblock and its manufacturing properties. To reduce water absorption, breezeblocks can be treated with sealants or coatings. In general, while they can absorb moisture, they are not as absorbent as other materials like wood or certain types of brick.
