Detailed Encyclopedia of Silica Densifiers

Silicon compacting agent is a high-performance green new admixture made of a variety of inorganic raw materials rich in cement active and reinforcing components through scientific and technical processes.

1. Technical performance of siliceous compacting agent:

After incorporating this agent, During the hardening process of cement, many colloidal suspended particles are formed, forming water-impermeable double salts, changing the original gel-space ratio of the cement stone, filling concrete pores and capillary pores, and densifying, thus improving the strength and impermeability of concrete and mortar.

2. How to use siliceous compacting agent:

1. The dosage is the weight of cement 3%.

2. This agent is first mixed with the mixing water into the mixer for one minute, and then mixed with the constituent materials of concrete or mortar into the mixer to achieve sufficient mixing. effect.

3. If there is precipitation during storage, stir it before use.

3. Scope of use of silica compacting agent:

1. Underground construction: subway, Parking lots, tunnels, mines, civil air defense projects, machine pits, cave storage, etc.

2. Build pools, swimming pools, water towers, storage tanks, oil tanks, large containers, toilets, etc.

3. It is widely used in mortar and concrete projects with waterproof, moisture-proof and high impermeability requirements.

4. Packaging and storage of silica density agent

This product should be stored in a cool place Store, prevent exposure to sunlight, and package in plastic barrels.

5. Silica dense agent construction method

1. Use ordinary silicon or silicic acid Salt cement, pozzolanic cement is prohibited;

2. Use medium-coarse sand, not fine sand, and the sand content is <2%.

3. Use gravel with mud content <2%;

4. Water Ash ratio﹤0.55;

5. The mechanical mixing time of mortar or concrete is not less than 2 minutes;

6. The mortar waterproof layer is 20-30mm;

7. Apply three times of application and three pressures to survive, and then calender twice after collecting water.

8. The slump of the concrete should be controlled at 30-50, and the surface should be polished with water. Sprinkling of water or dry cement is not allowed. </p
