Causes of dust, looseness, sand turning and insufficient strength on the ground

1, there are many grades of concrete, and low-grade concrete that does not meet the national technical standards is easy to cause;

2. The above-mentioned concrete aging may also be caused by the fact that the on-site pouring concrete is not operated according to the specifications, or the concrete ground construction is not maintained in time or the maintenance is not in place.

3. In the construction of concrete floor, it is also very important to seal and maintain the foundation surface. If the maintenance treatment is not in place, with the increase of service time, under the high-frequency use of forklift or trailer, coupled with carbonization, water erosion and weathering, the ground will soon turn sand, dust and loosen.

After the ground is hardened, will epoxy coating or self-leveling increase the cost? However, if the ground is loose and the sand is very serious, it is necessary to apply another layer of concrete or cement mortar, but the cost will increase even more, which is 2-3 times higher than the cost of hardening directly on the ground, which is really uneconomical. After FSD concrete sealing curing agent, also known as cement sealing curing agent or concrete penetrant, there are three generations of products in China market: the strength of concrete mainly comes from the silicon in the cement component of concrete, and the calcium silicate compound generated by calcium under the action of water is the substance that plays a major role in the strength of concrete. Active silicate ions contained in the concrete sealing curing agent react with free calcium ions in concrete that have not reacted into calcium silicate to generate hydrated calcium silicate, which makes the calcium ions in concrete further participate in the reaction, thus greatly improving the strength and hardness of concrete.

As long as the concrete hardener is well mixed with water and sprinkled on the ground, it is easy to construct (it can be constructed without professional technicians) and does not need maintenance. This greatly saves the maintenance cost, later time and energy and the risk to the company's reputation caused by loose ground.

A, the scope of application of concrete curing agent:

1, cement ground is polished, dusted, turned over and loosened.

2. Basements, garages, factories, shopping malls, airports, schools, hospitals, sand hardening and wear resistance enhancement treatment.

3. Plastering mortar surface grinding hardening repair.

4, concrete reinforcing agent penetrant.

5. The ground of underground garage is hardened and wear-resistant.

6. Hardening and wear-resistant treatment of concrete.

Widely used in electric power, warehousing and logistics, docks, parking lots, helipads, airstrips, high-hardness military facilities, printing, stationery, clothing, furniture, printing and dyeing, food, hardware, plastics, auto parts and other manufacturing plants, such as cement concrete floor, diamond sand hardened floor and terrazzo floor; It can also be used to renovate and reinforce old concrete floors and harden emery and terrazzo floors.

Main functions of concrete curing agent:

1, increasing the compactness, hardness and density of the surface layer.

2, increase the sealing and impermeability, waterproof and oil-proof.

3, increase durability and prolong service life.

4. Increase the surface gloss and make it more beautiful.

5, fill the surface gap, reduce the lime sand.

6. No waxing to reduce the later maintenance cost.
