What is water-reducing agent? Water-reducing agent, also known as dispersant or plasticizer, is the most widely used and indispensable additive in ready-mixed concrete. Because of its adsorption-dispersion effect, wet-slip effect, and wetting effect, after use, the water consumption of fresh concrete with the same working performance can be significantly reduced, thus improving the strength of concrete, A series of properties such as durability has been significantly improved. According to their effects, water-reducing agents can be divided into two types: ordinary water-reducing agents and high-efficiency water-reducing agents. Water-reducing agents can be compounded with other admixtures to form early-strength type, ordinary type, retarding type, and air-entraining type water-reducing agents according to engineering needs. Water-reducing agents can be divided into lignin sulfonates and their derivatives, polycyclic aromatic sulfonates, and water-soluble resin sulfonates according to their main chemical components, Aliphatic sulfonates, advanced polyols, hydroxy carboxylates, polyol complexes, polyoxyethylene ethers, and their derivatives, etc.
Action mechanism of water reducer Spatial steric hindrance: the hydrophilic branch chain in the structure of the water-reducing agent extends in the aqueous solution, thus forming a hydrophilic three-dimensional adsorption layer with a certain thickness on the surface of the adsorbed cement particles. When the cement particles are close, the adsorption layer begins to overlap; that is, the spatial steric hindrance between the cement particles occurs. The more the overlap, the greater the spatial steric repulsion force, the greater the resistance to the cohesion between the cement particles, and the better the concrete slump.
Scope of application of water-reducing agent It is suitable for pumping or normal concrete works with a strength grade of C15~C60 and above. It is especially suitable for preparing concrete works with high durability, fluidity, slump resistance, strength, and high requirements for appearance quality. Preparing high-fluidity concrete, self-compacting concrete, and Fair-faced concrete is extremely beneficial. The ordinary water-reducing agent should be used for concrete construction with a daily air temperature of more than five ℃. High-efficiency water-reducing agent should be used for concrete construction with a daily air temperature of more than 0 ℃. It is also suitable for preparing high-fluidity, high-strength, and steam-cured concrete.
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 the water-reducing agent. A large amount of large amount will be lower. The price of the water-reducing agent can be found on our company's official website.
