Polycarboxylate high-performance water-reducing agent is a variety of high-molecular organic compounds with polycarboxylate as the main body. It is produced by graft copolymerization and has strong water-reducing performance. It is green and environmentally friendly concrete with leading technology in the world today. admixture. It can be widely used in high-speed railways, nuclear power, water conservancy and hydropower projects, subways, large bridges, expressways, harbor terminals and various industrial and civil construction projects.

The popularity of machine-made sand has increased the proportion of water-reducing agents used in concrete, and the performance requirements have increased. Compared with river sand, most of the machine-made sand has rough surfaces, angular particles, irregular shapes, poor gradation, and usually higher content of stone powder, because machine-made sand produces cracks, voids or holes in the process of crushing and grinding these defects and fine particles increase the surface area of machine-made sand, absorb more free water, and at the same time enhance cohesion, so its expansion degree decreases, and the workability of concrete becomes poor. In order to improve its fluidity, it is necessary to maintain a good If the slump is low, it is necessary to increase the amount of water reducing agent, and specific functional additives can effectively solve the problems existing in concrete.

1. Anti-flocculant AF-301

Product description:

AF-301 anti-flocculant is a new type of admixture independently developed by Jiahua Chemical. It is mainly used for high viscosity, poor fluidity, rapid slump loss, and strength reduction of concrete caused by polyacrylamide flocculant in sand. question. This product has good water solubility and good adaptability, and can be used alone in concrete or in combination with other admixtures. This product can significantly increase the fluidity and slump performance of concrete. It can be widely used in ordinary concrete, pumped concrete, precast concrete and concrete with special requirements for mud resistance.

Technical indicators：

Features:

Washed sand contains polyacrylamide flocculant, which will cause problems such as high viscosity, poor fluidity, rapid slump loss, and strength decline of concrete. This product can effectively solve such problems. This product can be added to concrete alone, or it can be added together with other admixtures.

2. Viscosity reducer PV-105

Product description:

Because of its high strength, low weight and good integrity, high-grade concrete is more and more widely used in the construction market, especially in bridge engineering and high-rise buildings. However, due to the low water-cement ratio and a large amount of cementitious materials used in high-grade concrete, there are problems with high viscosity and slow flow speed, and the construction of the project is not used. In response to the market demand for this problem, Jiahua independently developed PV-105 viscosity-reducing additive, which can excellently increase the fluidity and workability of high-grade concrete and solve construction problems.

Technical indicators：

Features:

PV-105 viscosity reducing additive is mainly used in high-grade concrete. At present, the solution to the high viscosity of high-strength concrete is to reduce the viscosity of high-strength concrete by adding inorganic materials such as fly ash, ultra-fine limestone powder, silica fume, and microbeads. These viscosity-reducing measures all adopt the scheme of adding ultra-fine inorganic powder for physical filling and lubrication. The large amount of inorganic powder will inevitably lead to a substantial increase in the price of concrete; at the same time, due to the bulk density of ultra-fine inorganic powder And unit volume weight is small, inconvenient to transport and use. PV-105 can effectively solve the above problems. It is generally recommended to use PV-105 in combination, and the recommended dosage is 30-50% of the effective dosage of the total mother liquor, and the compounding ratio can be adjusted according to the improvement of the actual concrete viscosity, and it can also be used alone under special conditions. The use of PV-105 in high-grade concrete can effectively reduce the amount of mother liquor, which is cost-effective.

3. New structure alcohol amine accelerator

Product description:

The new structural alcohol amine quick-setting agent is a functional additive independently developed by Jiahua Chemical. It can be mixed into concrete to make the concrete harden quickly. Its dosage is generally 6% to 8% of the cement content in concrete, but it can make the concrete set in 5 minutes and finally set in 12 minutes. Their function is to accelerate the hydration and hardening of cement and form sufficient strength in a short period of time, which is widely used in tunnel engineering.

Technical indicators:

Features:

Alkali-free accelerator is mainly used in shotcrete in tunnel engineering. The product has the characteristics of short setting time, high early strength, low dosage, and environmental protection. At the same time, the product has good adaptability and excellent performance in different cements. conventional products on the market;

4. GS601

Product description:

Alcohol amine products are widely used in downstream products such as concrete reinforcers/synergists, accelerators, and grinding aids. The existing product structure is relatively single and cannot fully meet customer needs. GS601 is a new type of alcohol amine product developed by Jiahua.

Technical indicators:

Features:

GS601 can be used as a concrete reinforcing agent/synergist, which can significantly improve the early strength and later strength of concrete; at the same time, it has good compatibility with water reducing agents and has a synergistic effect; in addition, it can also be used in accelerators formulated to improve setting time and early strength;

5. Early strength additive PE205

Product description:

There are more and more applications for prefabricated components, segments, pipe piles, prefabricated concrete, etc. At present, it is generally required that the setting time is short and the early strength is high; PE205 is an early-strength polycarboxylate superplasticizer developed by Jiahua. High water rate, good early strength effect.

Technical indicators:

Features:

High water-reducing rate, good dispersion performance, and excellent performance at low water-cement ratio; accelerate early cement hydration, improve early strength; at low temperature, the early strength effect is better than conventional water reducers;
