What is water-reducing agent? Water-reducing agentis a concrete admixture that can reduce the mixing water consumption when the concrete slump is unchanged. Most are anionic surfactants, such as lignosulfonate, 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, Or reduce the unit cement consumption and save cement.
Action mechanism of water reducer 1. The solvated water film is formed through the hydrogen bond association between the water reducer and water molecules, which produces space protection, prevents the direct contact of cement particles, and prevents the formation of condensed structure 2. As an adsorption layer is formed on the surface of cement particles, it will inhibit the initial hydration of cement, thus increasing the free water content and improving the fluidity of cement paste 3. Some water-reducing agents will also introduce a certain amount of tiny bubbles to reduce the friction between cement particles, thus improving the dispersion and stability of cement paste.
Use of water-reducing agent 1. Without changing the proportion of various raw materials, the rheology and plasticity of the concrete can be greatly improved so that the concrete construction can be carried out by gravity flow, pumping, vibration-free, and other methods to improve the construction speed and reduce the construction energy consumption 2. Adding concrete superplasticizer can increase the service life of the concrete by more than twice, even if the normal service life of the building is extended by more than times 3. Reduce the shrinkage rate of concrete solidification and prevent cracks in concrete components: improve the frost resistance, which is conducive to winter construction.
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.
