Greatech has 8 concrete production lines of various types, with an annual design and production capacity of more than 4 million cubic meters of ready-mixed concrete, capable of producing ready-mixed concrete with strength levels of C10-C60. Greatech’s high-quality concrete products mainly include: ordinary concrete, high-performance concrete, high dropping non-segregating concrete, self-waterproof concrete, self-stressing concrete, water-adaptable concrete, anti-freeze concrete, high-strength concrete, underwater concrete, impermeable concrete Concrete, fiber concrete, self-compacting concrete, lightweight aggregate concrete, polymer concrete, surface-resistant concrete, wear-resistant concrete, dry hard concrete, heat-resistant concrete, non-sparking concrete, etc.

Ordinary concrete: cement is used as cementing material, sand and stone as aggregate material; cement concrete obtained by mixing with water (which may contain additives and admixtures) in a certain proportion.

High-performance concrete: select high-quality conventional raw materials, reasonably mix with admixtures and mineral materials, adopt the water-to-binder ratio (<0.45) and optimize the mix ratio, and make concrete with excellent mixing properties, mechanical properties, durability and long-term performance through ready-mixed, green production methods and strict construction measures. 　

Advantages: ①good fluidity, good construction performance, good material extraction and vibrating; ②high performance concrete has good durability and long life, which can reach more than 50-100 years; ③surplus strength is more than 5-8MPa, suitable for freezing resistance, sulfate resistance, emulsion ion penetration resistance, early anti-cracking performance and other durability requirements, as well as large-volume, underwater, bridge, road and other key projects.

Self-waterproof concrete: use cement, aggregate as raw materials, or mix with a small amount of additives, high molecular polymers, fibers and other materials by adjusting the mix ratio, the pores can be inhibited or reduced, the pore characteristics are changed, and the interface between the raw materials is increased. Its compactness and crack resistance make it have good volume stability and anti-permeability.

Advantages: ①convenient construction, shorten the construction period, and greatly reduce the comprehensive waterproof cost; ②improve the impermeability, and the impermeability level can reach P20 or more; ③improve the crack resistance of the rigid roof structure; ④good durability, the same life span as the building, reducing the cost of other work and use; ⑤ high strength, green and environmental protection.
