What is water-reducing agent? Water-reducing agent can reduce water consumption for mixing while keeping the concrete slump unchanged. Most are anionic surfactants, such as lignosulfonate, naphthalenesulfonate formaldehyde polymer, etc. Role: adding concrete mixture can disperse cement particles, improve its workability, reduce unit water consumption, improve the fluidity of concrete mixture.
Use of water-reducing agent 1. Without changing the proportion of various raw materials (except cement) and the strength of concrete, the amount of cement can be reduced. Adding 0.2% and 0.5% concrete water-reducing agents with cement quality can save more than 15% and 30% of the amount of cement 2. Without changing the proportion of various raw materials (except water) and the slump of concrete, reducing the amount of water can greatly improve the strength of concrete. The early and late strengths are 60% and 20% higher than concrete without a water reducer. Through water reduction, C100-grade high-strength concrete can be poured.
Action mechanism of water reducer 1. The water-reducing agent will absorb at the solid-liquid interface, reduce the surface tension, improve the surface wetting state of cement particles, reduce the thermodynamic instability of cement dispersion, and obtain relative stability 2. The water-reducing agent will produce directional adsorption on the surface of cement particles, make the surface of cement particles have the same charge, and generate electrostatic repulsion, thus destroying the flocculent structure of cement particles and dispersing the cement particles. For polycarboxylate and sulfamate superplasticizers, the adsorption of the water-reducing agent is in the form of a ring, lead, and gear, thus increasing the distance between the cement particles that generate electrostatic repulsion and showing better dispersion and slump retention.
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.
