What are the specifications and sizes of Tangshan cement bricks?

Tangshan cement brick specifications and sizes are of great concern to customers. Common Tangshan cement brick specifications in the market include the standard brick (240*115*53mm), the eight-hole brick (240*115*90mm), and the hollow brick (390*190*190mm). The standard for Tangshan cement bricks (using the 240×115×90mm wall brick as an example) is a strength grade of 10MPA, with materials including ordinary concrete or high-sulfate fly ash concrete. The formula for Tangshan cement bricks is different from other formulas and contains secret ingredients known to industry professionals: clay, cement, admixtures, and water. The addition of 425# ordinary portland cement during the blending process enhances the brick's strength and water resistance, preventing cracking after immersion. Otherwise, general bricks tend to crack.
