Dry-mixed B-Type Lightweight Aggregate Concrete, produced by Changzhan Factory in Langfang

Lightweight aggregate concrete is a type of lightweight concrete, mainly composed of cement and aggregates, with various additives (combined with lightweight aggregates) added. It is formulated by replacing stone or ceramic balls as filling aggregates with lightweight aggregates, resulting in an compressive strength greater than 5.0 Mpa. After molding, it is a new type of lightweight thermal insulation concrete with a large number of sealed pores. LC high-strength dry-mixed composite lightweight aggregate concrete is a uniform dry-mixed powder produced from cement, fly ash, and admixtures in a factory; the composite lightweight aggregate is made by blending crushed waste particles or mineral hollow glass beads with inorganic cementitious materials. It is mixed with pre-mixed powder and water on-site to form a composite lightweight aggregate bedding with good strength, thermal insulation properties, excellent volume stability, and excellent durability, making it an environmentally friendly lightweight building material.Primarily used for ground corridors and other specific high-pressure-resistant areas.

Lightweight aggregate concrete is used for indoor subflooring or as required by the design, with LC7.5 lightweight aggregate concrete having a dry apparent density ≤1000kg/m³ and a thermal conductivity ≤0.25W/(m.K).

Product Advantages
Lightweight: The addition of particles reduces the density of concrete and increases its porosity, allowing for a reduction in concrete weight by up to 30% to 60% with the same volume. This lowers the load on buildings and extends their service life.

Environmental Protection: Overcomes the challenge of harmless waste treatment, effectively reducing environmental pollution, protecting ecological balance, and lowering production costs. It also finds new recyclable paths for waste insulating materials, while providing the enterprise with favorable social and economic benefits.
Absorption: With low density and numerous pores, it is an excellent soundproofing material. When sound waves are transmitted to the surface of the rigid foam and follow the material's pores into the interior, they cause air within the pores and fine particles of the material to resonate.The vibration of fibers, due to the effects of friction and viscous resistance, converts a considerable portion of sound energy into heat and dissipates it.
Insulation: Rigid foam has higher R-value and lower thermal conductivity. It is currently the most widely used insulation material internationally.
Fire Retardant: This product meets the A级 fire resistance standard.
