What are the characteristics of lightweight aggregate concrete?

Ignition Characteristics A2 Level: Retains fire resistance over 1000°C, will not ignite under high temperatures.

Insulation: The thermal conductivity is at least 0.043 W/m.k, with a seamless insulation layer that meets 75% of environmental protection and energy-saving requirements.

High Compressive Strength: Tensile strength exceeds 0.69 Mpa, reaching up to 20 Mpa.

Low water absorption rate: ≤6%.

5. Longevity: Matches the lifespan of residential construction.

6. Excellent Soundproofing: 7cm thick granular concrete can effectively reduce noise by 23dB, achieving special soundproofing effects.

7. Excellent Seismic Performance: The elastic mold accounts for only 1% of the cement concrete.

8. Lightweight: With a relative density of 215-365 kg/m³, this concrete boasts its lightweight properties, excellent thermal insulation, and fire resistance. The tensile strength of structured lightweight aggregate concrete can reach 70 MPa. Compared to similar cement concrete, it can reduce its own weight by 20% to over 30%.

9. Under normal conditions, there is also a significant amount of shrinkage and plastic deformation. There is a positive correlation between the density and compressive strength of the elastic mold for lightweight aggregate concrete. The lower the density, the lower the compressive strength and the elastic modulus, with the elasticity of this concrete being 25-65% lower compared to similar cement types.
