Where can I find early strength water reducing agent?

Anhui Yulong develops and produces early-strength superplasticizers and supplies them nationwide, with independent research and development and quality assurance. In China, it currently includes Beijing, Shanghai, Guangzhou, Shenzhen, and other first-tier cities as the main supplier of early-strength superplasticizers.

Polycarboxylate Superplasticizer is a high-performance water-reducing agent and a cement dispersant in cement concrete applications. Widely used in highways, bridges, dams, tunnels, high-rise buildings and other projects.

In many concrete projects, traditional high-efficiency concrete such as naphthalene series is increasingly unable to meet project needs due to limitations in technical performance. The new generation of water-reducing agent that has attracted much attention at home and abroad, the early-strength high-performance water-reducing agent, has truly designed an effective molecular structure based on the mechanism of dispersed cement. It has a super-dispersed type and can prevent the loss of concrete slump. It does not cause obvious retardation, exerts a high plasticizing effect at low dosage, has good fluidity retention, has a large degree of freedom in cement adapting to a wide range of molecular structures, has many synthesis technologies, and has great room for high performance, and has a great effect on concrete reinforcement. Significantly, it can reduce the shrinkage of concrete and has extremely low harmful substance content and other technical performance characteristics, which gives the concrete excellent construction workability, good strength development, excellent durability, early-strength series high-performance water-reducing agent with good comprehensive technology Performance advantages and environmental protection characteristics meet the needs of modern concrete projects. Therefore, early-strength high-performance water-reducing admixtures are gradually becoming the first choice admixtures for formulating high-performance concrete. According to reports, the use of early strength admixtures in Japan accounts for more than 80% of all high-performance admixture products, and North America and Europe also account for more than 50%. In my country, early-strength water reducing agents have been successfully used in large-scale water conservancy, bridges, nuclear power, and railway projects such as the Three Gorges Dam, Sutong Bridge, Tianwan Nuclear Power Station, and Beijing-Shanghai High-speed Railway, and have achieved remarkable results.

At the same time, there are also some problems with early-strength superplasticizers: 1. Insufficient slump retention in high-temperature environments; 2. Strong temperature sensitivity, the same early-strength reduction Aqueous agents are constructed in different seasons, and the slump retention of concrete varies greatly; 3. There are few functional products, which are difficult to meet the needs of ultra-high and ultra-long distance concrete pumping, negative temperature construction, preparation of ultra-early strength concrete, and high durability of concrete. and other requirements; 4. High viscosity. In the preparation of concrete with high admixture materials and low water-cement ratio, the viscosity of concrete is high, which is not conducive to construction; 5. It is highly sensitive to the mud content of sand and gravel aggregates. [2] 6. It has poor adaptability to machine-made sand and is sensitive to the dosage, which affects construction.

Early-strength water-reducing agent foam suppressor is specially designed for early-strength water-reducing admixtures. The main component is modified polyether material which is refined using special technology. The product has stable performance, no delamination or precipitation during long-term storage, and no crystallization in winter. It is especially suitable for formulating water-reducing agents for high durability, high fluidity, strength pumping concrete and fair-faced concrete with extremely high quality requirements. It has fast defoaming speed, long foam suppression time, high temperature resistance, strong alkali resistance, and strong stability. Particularly suitable for defoaming and suppressing foam under alkaline conditions.

Characteristics of early strength water reducing agent and foam suppressor:

1. Defoaming, It has strong foam-inhibiting power and a small dosage, which does not affect the basic properties of the foaming system.

2. Good heat resistance, chemical stability, strong versatility, non-flammable, non-explosive, and no product impact.

3. Its performance is comparable to imported products, and its price has obvious advantages. </p
