The mechanism of action of water reducing agents mainly includes the following aspects: 1. Dispersion effect: The surfactant in the water reducing agent can form a layer of dispersant film on the surface of cement particles, increasing the electrostatic repulsion force between cement particles, thereby reducing particle aggregation and sedimentation, and improving the fluidity and…

Chelating agents are compounds that can form stable complexes with metal ions. The composition of chelating agents is usually organic compounds, and common chelating agents include organic acids, organic amines, and organic sulfides. Organic acids are one of the most common chelating agent components, and commonly used organic acids include acetic acid, oxalic acid, acetic…
Water reducing agent is a chemical substance added to concrete or mortar, which can reduce its cement content, improve its fluidity and workability. The process of action of water reducing agents is as follows: 1. Dispersion: The active ingredients in the water reducer can interact with the surface of the cement particles, change their Surface…

Differentians are an additive widely used in the particle system. The main role is to disperse solid particles evenly and prevent it from re -aggregating. The mechanism of the scattered agent can be explained in the following aspects: Adsorption effect: The molecule of the active compound (such as the surfactant) in the dispersant will be…
The water reducing agent is a additive commonly used in concrete and mortar. The mechanism of decentralization is as follows: Surface active agent: Water reduction agent usually contains surfactant components. These compounds form a adsorption layer in water. This adsorption layer can reduce the surface tension of water, making water easier to contact solid particles…
