As an admixture that can significantly improve the early strength of concrete, the early strength agent has a great influence on the early performance of lightweight composite foamed foam concrete.
Overview of concrete hardener early strength agent
Concrete hardener, early strength agent, used in foam concrete, is one of the concrete admixtures. Early strength agent refers to an admixture that can increase the early strength of concrete without significant influence on the later strength. The main function of the early strength agent is to accelerate the hydration rate of cement and promote the development of early strength of concrete. TR-31 early strength agent has the advantages of stable performance, strong adaptability, low cost and high early strength effect.
Advantages of concrete hardener
(1) Rapid solidification and hardening, adjustable solidification time;
(2) The late strength is steadily improved, and the early strength is increased by 10-30%;
(3) It has micro-expansion characteristics, and more calcium sulfate hydrate will be generated during the hydration process, which will slightly expand the cement, thus having a good compactness.
(4) Excellent corrosion resistance, can still exert high strength under low temperature conditions.
How to use concrete hardener early strength agent
1. Dosage: 0.8-1.5% of cement;
2. In order to maintain the uniform quality of the concrete mixed with TR-31, extend the mixing time by 1-2 minutes;
3. If the reagent is damp and agglomerated, it must be crushed or weathered before use, and its performance remains unchanged.
Application of concrete hardener early strength agent
(1) The concrete hardener early strength agent does not contain chloride ions and has no corrosive effect on steel bars. Suitable for all civil, industrial buildings and prestressed reinforced concrete components, mortar, etc.
(2) The concrete hardener early strength agent is suitable for low temperature construction in early winter and early spring;
(3) Concrete hardener early strength agent is used to strengthen and modify Portland cement, especially slag cement.
