  • Differences Between Clay Bricks and Concrete Blocks

    Compressive strength of concrete blocks is higher than clay bricks. Concrete blocks have much higher water resistance. They do not absorb water thus it can be said they have a consistency close to waterproof. Concrete has shorter expected life than clay brick. Concrete blocks give efficient results up to 100 years.
