The four major advantages of Anhui Yulong Silica Density Agent, the best siliceous density agent manufacturer

1. Improve the workability of concrete

Workability refers to the ease of construction of fresh cement concrete in various processes Operation (mixing, transportation, pouring, tamping, etc.) and can achieve uniform quality and dense molding performance, which means fluidity, cohesion and water retention. Also known as the workability of concrete. It has good workability and is easy to fill the formwork. The concrete is not prone to honeycombs, holes and pitting.

2. Solve the problem of temperature shrinkage cracking

Concrete temperature cracks are caused by the inner and outer parts of the concrete. Cracks caused by temperature changes. When concrete is first poured, it is in a state of plastic flow. The cement will generate a large amount of hydration heat during the hydration reaction and condensation process, causing the volume to expand freely. When the maximum temperature is reached, the concrete is basically solidified, and then the concrete begins to cool down and shrink. Cracks occur. At the contact point with the rock foundation, the shrinkage of the concrete is constrained by the rock foundation and produces a large tensile stress, which may cause foundation penetration cracks and deep cracks. In the event of a cold wave, the temperature difference between the inside and outside is relatively large, and the deformation is constrained by the internal concrete. Concrete can develop surface cracks. In addition to improving the quality of concrete, the main measures to prevent cracks in concrete are concrete temperature control. By incorporating siliceous compacting agent, the temperature inside and outside the concrete is almost kept consistent, thus avoiding temperature shrinkage cracking.

3. Improve compressive and tensile strength

After incorporating silica dense agent ,28 The compressive strength can be increased by 10%, and the tensile strength can be increased by 11%, which increases the ultimate tensile value of concrete, improves the toughness of concrete, and better avoids concrete cracking.

4. Replace expansion agent pumping agent and fiber

Through a large number of engineering practices, Concrete mixed with expansion agents will crack more seriously in the later stage. Although adding fiber provides concrete with a certain degree of resistance to cracking, it affects the workability. After being mixed with KOLO inorganic nano-anti-cracking agent, it can improve the anti-cracking ability without affecting the workability. At the same time, pumping agents can be omitted, and it has a good slump protection function, and the slump is lost within 2 hours. No more than 2CM. </p
