Product Description
Concrete hydration heat inhibitor
[Hydration Heat Inhibitor]
The concrete anti-impact and wear-resistant admixture is composed of a variety of special functional materials—including organic phosphonic compounds, phosphate compounds, and auxiliary components—carefully matched and compounded. When a hydration heat inhibitor is added to ready-mixed concrete, it can regulate the cement hydration process, thereby reducing the rate and peak value of early-stage hydration heat release. This results in a more gradual rise in internal concrete temperature and helps minimize cracks caused by temperature differences.

Product Introduction
The concrete anti-impact and wear-resistant admixture is composed of a variety of special functional materials—including organic phosphonic compounds, phosphate compounds, and auxiliary components—carefully matched and compounded. When a hydration heat inhibitor is added to ready-mixed concrete, it can regulate the cement hydration process, thereby reducing the rate and peak value of early-stage hydration heat release. This results in a more gradual rise in internal concrete temperature and helps minimize cracks caused by temperature differences.
Product features and advantages
1. The temperature control effect is remarkable, reducing early hydration heat by more than 20%, lowering the internal concrete temperature rise by 6–10℃, and delaying the onset of the peak temperature.
2. Has minimal impact on concrete performance, requires low dosage, exhibits excellent compatibility with cement and other admixtures, and does not affect workability during construction.
3. It offers multiple benefits, enhancing the compressive and tensile strength of concrete in the mid- and late stages, optimizing the internal pore structure, and improving impermeability and durability.
【Scope of Application】
It can be widely used in various concrete projects with stringent temperature-control requirements, and is particularly well-suited for large-volume concrete structures.
1. Hydraulic and Hydroelectric Engineering: Dams, hydropower plant buildings, water diversion tunnels, and more.
2. Transportation Engineering: Bridge piers, cap beams, railway and highway subgrades, etc.
3. Architectural Engineering: Thick-bottom slabs for high-rise buildings, underground integrated utility tunnels, large-scale basements, and the like.
4. Special Projects: Shotcrete applications in harsh environments such as nuclear power facilities, military bunkers, coal mines, and salt lakes.
