High Performance Concret...

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.

Dry mortar

According to different requirements, the ratio is selected, and different additives such as high-quality cement, quartz sand, polymer cement and other additives are uniformly mixed by machinery to meet different construction requirements.


Greatech mortar products mainly include: plastering mortar, masonry mortar, light plastering mortar, light masonry mortar, thin plastering and masonry mortar , cushion mortar, general mortar for masonry plastering, thermal insulation mortar , thermal insulation bonding mortar, tile bonding mortar, waterproof mortar, anti-cracking mortar, self-leveling mortar, gypsum plastering mortar, caulking mortar, grouting for steel connection.


Advantages: no hollowing, no cracking, high quality, less waste, and high environmental protection.


Plastering mortar: use cement as a cementitious material and apply it on the base surface of the building and decoration interior and exterior walls, overlays, bottom surfaces, and ceilings to achieve the effect of leveling or providing protection.


Main advantages: ①easy to use, just add water and stir to use; ②low waste, automatic measurement, ready-to-use after mixing; ③can effectively control the hollow and cracking, special fabrics and professional construction methods to ensure the quality of the finished product; ④environmental protection, no dust, noise pollution.


Masonry mortar: mortar used to bond bricks, stones, blocks and so on into masonry. It plays a role in transferring loads and is an important part of masonry.


Main advantages: ①easy to use, just add water and stir to use; ②good water retention, convenient for construction; ③water saving, no need to do pre-wetting treatment on the wall; ④good workability, strong adhesion, low shrinkage; ⑤ It can ensure that the wall is flat and prevent the wall from tilting.


Anchor (rod) mortar: use cement as the base material and add an appropriate amount of natural high-strength aggregates, concrete admixtures and other dry-mixed materials.


Main advantages: ①fast hardening and high strength; ②high self-flowing, can be used only by adding water and stirring on site; ③micro-expansion with high bonding strength; ④corrosion resistance, with good sewage erosion resistance.


Cushion mortar: mortar used for ground leveling, slope finding, cushioning and backfilling.


Main advantages: ①easy to use by adding water and stirring, shorten working time; ②Less waste and consumption; ③Easy to mix and pave construction, low shrinkage rate; ④Clean site, civilized construction, and provide management level.


Tile bonding mortar: It is mainly used as an adhesive for bonding ceramic tiles and surface tiles, also known as polymer tile bonding mortar.


Main advantages: ①high bonding strength, fast hardening speed; ②convenient for construction, mixing with water, direct bonding without foaming bricks; ③strong tensile strength, good water retention, compression resistance, water resistance, alkali resistance and weather resistance ④thin-layer construction can be realized, cost saving, environmental protection, and low shrinkage rate.


general-purpose mortar for masonry and plastering: general-purpose mortar that is bonded between the bricks and the surface of the wall should be used for leveling and protection of the wall.


Main advantages: ①easy to use, just add water and stir to use; ②good workability, strong adhesion, low shrinkage; ③no hollow and cracking, strong hardness, good look; ④the wall is smooth to prevent the wall from tilting.

Quality Gravel

Greatech’s quality gravel has been upgraded from the traditional two-level ratio to the three-level ratio, including: 5-10mm, 10-16mm, 16-25mm. The gradation is reasonable, the content of needle flakes is strictly controlled, the gravel shape is good, and it can save save cementitious material and can meet the requirements of high-strength concrete.


Quality Machine-made Sand

Strictly control the content of stone powder, MBV (methylene blue value, indicating the size of the mud content in the machine-made sand) is less than 1.0, the fineness modulus is stable, the particle morphology is round, the gradation is good, the porosity is low, which can significantly save cementitious material to improve the compactness and durability of concrete.


Quality Stone Powder

It has a wide range of uses, mainly in the fields of construction and building materials, feed processing, coal power desulfurization and chemical industries.
