What are the types of water reducing agents?

What is Water reducing agent?
Water reducing agent is a kind of concrete admixture which can reduce the mixing water consumption under the condition of keeping the slump of concrete basically unchanged. Most of them are anionic surfactants, such as lignosulfonate, naphthalene sulfonate formaldehyde polymer, etc. Adding concrete mixture can disperse cement particles, improve its workability, reduce unit water consumption and improve the fluidity of concrete mixture. Or reduce the unit cement consumption and save cement.
Classification of Water reducing agent
1. Appearance is divided into aqua and powder. The solid content of the aqueous solution is generally 20%, 40% (also called mother liquor) and 60%, and the solid content of powder is generally 98%. Uses of Water reducing agent
2. According to the water-reducing and enhancing ability of water-reducing agents, it can be divided into ordinary water-reducing agents (also called plasticizers, the water-reducing rate is not less than 8%, represented by lignosulfonates), high-efficiency water-reducing agent (also called superplasticizer, the water-reducing rate is not less than 14%, including naphthalene series, melamine series, sulfamate series, aliphatic series, etc.) and high-performance water-reducing agent (the water-reducing rate is not less than 25%, represented by a polycarboxylate series water-reducing agent), which can be divided into early strength type, standard type and slow setting type.
3. According to the chemical composition, it is usually divided into lignosulfonate superplasticizer, naphthalene superplasticizer, melamine superplasticizer, sulfamate superplasticizer, fatty acid superplasticizer and polycarboxylate superplasticizer.
Performance characteristics of Water reducing agent
1. the dosage is low, the water-reducing rate is high, and the water-reducing rate can be up to 45%;
2. The slump loss is small with time, and the slump loss rate of ready-mixed concrete is less than 5% for one h and less than 10% for two h;
3. The reinforcement effect is remarkable; the three-dimensional (abbreviation of three dimensions) compressive strength of concrete is increased by 50~110%, the 28d compressive strength is increased by 40~80%, and the 90d compressive strength is increased by 30~60%;
4. The workability of concrete is excellent, without segregation and bleeding, and the appearance colour of the concrete is uniform. When used for preparing high-grade concrete, the concrete has good cohesiveness and is easy to mix;
5. Moderate air content, no adverse effect on the elastic modulus of concrete, and good frost resistance and durability;
6. It can reduce the early hydration heat of cement, which is beneficial to mass concrete and summer construction;
7. Excellent adaptability, good compatibility between cement and admixture, good temperature adaptability, and good compatibility with different kinds of cement and admixture, which solves the problem of poor compatibility between other water-reducing agents and cementitious materials;
8. Low shrinkage, which can obviously reduce the shrinkage of concrete, and its frost resistance and carbonation resistance are obviously better than those of ordinary concrete; Significantly improve the volume stability and long-term durability of concrete;
9. The alkali content is extremely low, and the alkali content is 0.2%, which can effectively prevent the occurrence of an alkali-aggregate reaction.
10. The product has good stability, no stratification and precipitation during long-term storage, and no crystallization at low temperatures;
11. The product is green and environment-friendly, free of formaldehyde, and is an environment-friendly product;
12. Good economic benefit, the comprehensive engineering cost is lower than that of other types of products, and cement can be saved by 15-25% under the same strength condition.
Price of Water reducing agent
Water reducing agent particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Water reducing agent. A large amount of large amount will be lower. The price of Water reducing agent can be found on our company's official website.
