Why water reducer is an indispensable additive
What is water-reducing agent?
Water-reducing agent is a concrete admixture that can reduce the mixing water consumption. Most are anionic surfactants, such as naphthalenesulfonate formaldehyde polymer, etc. After adding the concrete mixture, it can disperse cement particles, improve its workability, reduce unit water consumption, and improve the fluidity of the concrete mixture.
Main classification of water-reducing agent
The appearance is divided into water and powder. The solid content of water is generally 20%, 40% (also called mother liquor), or 60%, and the solid content of powder is generally 98%; it is divided into common water-reducing agent (also known as a plasticizer, with a water reduction rate of not less than 8%, represented by a lignosulfonate, high-efficiency water-reducing agent (also known as superplasticizer, with a water reduction rate of not less than 14%, including naphthalene series, melamine series, aminosulfonate series, aliphatic series, etc.) and high-performance water-reducing agent (water reduction rate of not less than 25%, represented by a polycarboxylic acid series water-reducing agent). It is also divided into early-strength type, standard type, and retarding type. It is divided into lignosulfonate, cyclic aromatic salt, Water-soluble resin sulfonates, naphthalene series superplasticizer, aliphatic superplasticizer, amino superplasticizer, polycarboxylic acid superplasticizer, etc. According to chemical composition, they are generally divided into lignosulfonate superplasticizer, naphthalene series superplasticizer, melamine series superplasticizer, aminosulfonate, fatty acid series superplasticizer, polycarboxylic acid series superplasticizer.
Action mechanism of water reducer
Dispersion effect: after mixing cement with water, due to the hydration effect of cement particles, the surface of cement particles forms a double-layer structure, making it form a solvated water film, and the surface of cement particles has an anisotropic charge, which causes the association between cement particles, making the cement slurry form a flocculation structure, so that 10%~30% of the mixing water is wrapped in the cement particles, and cannot participate in free flow and lubrication. Thus, the fluidity of the concrete mixture is affected. When water reducer is added, the molecules of water reducer can be adsorbed on the surface of cement particles directionally so that the surface of cement particles has the same charge (usually negative charge), forming electrostatic repulsion, promoting the dispersion of cement particles, the disintegration of flocculation structure, releasing the wrapped water, and participating in the flow, thus effectively increasing the fluidity of concrete mixture.
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.
