At first, concrete additives were used only to save cement. With the development of construction technology, admixture has become the main measure to improve the performance of concrete.
What are advantages of concrete additives?
It can reduce the water consumption of concrete. Or the fluidity of concrete can be increased without increasing water consumption.
The setting time of concrete can be adjusted.
Reduce bleeding and segregation. Improve workability and water elutriation resistance.
The slump loss can be reduced. Increase the pumpability of pumping concrete.
It can reduce contraction. The addition of expansive agent can also compensate for shrinkage.
Delay the initial hydration heat of concrete. Reduce the temperature rise rate of mass concrete and reduce the occurrence of cracks.
Improve the early strength of concrete. Prevent freezing at negative temperature.
Improve strength, increase frost resistance, impermeability, wear resistance, corrosion resistance.
Control alkali-aggregate reaction. Prevent the corrosion of steel bar and reduce the diffusion of chloride ion.
Made into concrete with other special properties.
Reduce the viscosity coefficient of concrete.
Where are concrete admixtures used?
1. It is suitable for mass concrete, high-strength and high-performance concrete, roller compacted concrete, concrete constructed in hot weather, concrete poured in a large area, concrete produced by cold joints, concrete that needs to be parked or transported for a long time, self-leveling vibration-free concrete, slip form construction or horizontal construction and other concrete that needs to delay setting time.
2. It is suitable for different grades of concrete under the daily minimum temperature of 5 degrees Celsius, as well as various continuous pouring projects of high flow concrete, commercial concrete, pumping concrete, prestress and reinforced concrete.
3. It is not suitable to be used alone for concrete with early strength requirements and steam curing concrete.
