The production of concrete water-retaining and tackifying agents can solve the problem of concrete viscosity-increasing and water-retaining properties without pressure.

Anhui Yulong New Material Technology Co., Ltd. is an enterprise specializing in water-retaining tackifiers and anti-segregation agents. Our company produces water-retaining tackifiers. This product has excellent water retention, workability, pumpability and adaptability. It can improve the water retention of concrete and mortar, avoid segregation and bleeding; improve the sensitivity of water-reducing agents and improve the anti-sag properties of accelerating agents. Used in the compounding and synthesis of water reducing agents and accelerating setting agents, it can not only improve product performance but also reduce production costs.

Adding admixtures to pumped concrete can improve the workability of the concrete. Its impact on pumping construction cannot be underestimated. Generally, admixtures have the functions of retarding, water reducing, and strengthening. The compound property Powder admixtures also increase the micro-expansion and anti-permeability effect. For pumping concrete construction, the main consideration is the impact of admixtures on the pumping effect. Generally speaking, the following aspects can be considered.
Air content. Most admixtures have an air-entraining effect after being added to concrete, producing a certain proportion of particulate bubbles. If the air content is too low, it will affect the fluidity and pumpability of concrete, so it should be controlled within a reasonable range. In addition, adjusting the gas generating agent in the admixture will also increase or decrease the strength level of concrete.
Water reduction rate. An important indicator of admixtures is the water reduction rate. Reducing water consumption and lowering the water-cement ratio are important means to improve the strength of concrete. Generally, water consumption is reduced by about 15%.
Slump. After using water reducing agent, when the concrete is transported to the construction site, the concrete pump pipe is blocked due to the sharp loss of slump.
1. Admixtures must have factory certificates.
2. The dosage must be determined by trial preparation.
3. The proportion of materials is accurate, the allowable error is 2%, and no leakage is allowed.
4. When preparing solutions, the minimum dosage is 50kg. It is strictly prohibited to prepare non-integer solutions to prevent mismatching.
5. Stir the solution in the vat frequently to prevent precipitation and caking.
6. The amount of water used for concrete should be deducted from the amount of solution.
7. The solid additives are pre-weighed according to the required amount of each vat of solution and packaged in plastic bags for later use.
8. The storage of admixtures shall be carried out according to the product instructions. It should be strictly distinguished from other easily confused materials and marked.
9. Each time a solution is prepared, a weighing record must be made for verification.
10. All measuring instruments must pass metrological verification.

Accelerating setting agent Accelerating setting agent is an admixture that can quickly set and harden concrete. The main types of accelerators are inorganic salts and organic substances. The commonly used accelerating setting agents in my country are inorganic salts. Inorganic salt accelerating setting agents can be roughly divided into three categories according to their main components: accelerating setting agents with sodium aluminate as the main component; accelerating setting agents with calcium aluminate, calcium fluoroaluminate, etc. as the main component; accelerating setting agents with silicic acid as the main component It is an accelerator containing salt (NaSiO2) as the main component. The main models include Red Star 1, 711, 782, 8604, WJ-l, J85 and so on. 1. Commonly used accelerating setting agent Hongxing Type 1 accelerating setting agent is a powder prepared from alumina clinker (the main component is sodium aluminate), sodium carbonate and quicklime in a mass ratio of 1:1:0.5 things. The appropriate dosage is 2.5%~4.0% of the cement mass. 7ll type accelerating setting agent is made by grinding alumina clinker and anhydrous gypsum in a mass ratio of 3:1. The appropriate dosage is 3% to 5% of the cement mass.
