Both solid and hollow concrete bricks/blocks are used during the construction of walls, but can be used for different purposes as well.
Concrete bricks/blocks are made of cement, sand, gavel, stone and water. Concrete bricks/blocks are useful for many construction projects, roadways, building load-bearing masonry walls, or creating partition walls.
In order to choose the right product, you need to take into consideration how you’ll be using it and the properties you want to emphasize. Different types of concrete bricks are designed to be used at different places in a structure, such as over windows or at corners. Some need more reinforcement than others, and some are better at thermal and sound insulation.
