Overview of Concrete Early Strength Agent

Cement strength, also known as concrete strength concrete hardener, is an agent that can greatly change the final setting time while ensuring the quality of concrete is reduced.

Concrete strength can improve the compressive strength of concrete and speed up the molding speed. The sleeve accelerates the turnover of the formwork, saves the amount of formwork, saves energy, saves cement, reduces production costs, and improves the output of concrete products.

Our concrete strength 31B can reduce the activation energy of the cement hydration reaction, increase the hydration reaction rate, and promote rapid strength development during the hardening period. And it can significantly improve the cement mortar products. Ultra-early strength within 12 hours. Abnormal does not affect the durability of cement mortar products.

Application of Concrete Early Strength Agent

1) Concrete strength 31B does not contain chlorine ions and has no rusting effect on steel bars. It suits all civil and industrial buildings, prestressed reinforced concrete members, mortar, etc.

2) Concrete strength 31B is suitable for construction under low temperatures in early winter and early spring;

3) Concrete strength 31B is used for Portland cement, especially for the reinforcement and modification of slag cement.

The Advantage of Concrete Early Strength Agent

1) Excellent super compressive strength of concrete performance can greatly improve the strength development under normal temperature, low temperature, or thermal curing temperature conditions. Concrete strength tests can verify its efficacy.

2) Concrete strength can improve the durability of cement mortar and board and won’t shrink the strength of cement mortar and board；

3) Concrete strength can shorten demolding time and speed up mold turnover；

4) Concrete strength can shorten or even eliminate the steam curing process, save energy, and reduce consumption；

5) Concrete strength can reduce the amount of glue.

FAQs of Concrete Early Strength Agent

Q1

Why can early strength agents accelerate the hardening of concrete?

Answer: 

Early strength agents mainly achieve the effect of accelerating hardening by changing the chemical reaction rate of certain components in cement. For example, chlorine salt early strength agents mainly accelerate the hydration and hardening of cement by accelerating the hydration of C3S.

Q2

What projects are early strengthening agents suitable for?

Answer: 

Early strength agent is suitable for projects that need to quickly reach the design strength, such as emergency repairs, winter construction, etc. However, it should be noted that because chloride salt early-strength agents may cause corrosion of steel bars, their use is restricted in most concrete projects.

Q3

What is the working principle of sulfate early strength agent?

Answer: 

The sulfate-based early strength agent has a more obvious effect under lower curing temperature conditions and in cement with low early strength, and it also improves the later strength to a certain extent. It not only accelerates the strength growth under normal and low temperature conditions, but also improves the strength of concrete under steam curing conditions.

Q4

What are the organic series early strengthening agents?

Answer: 

Organic series early strength agents mainly include triethanolamine, triisopropanolamine, methanol, ethanol, etc., among which triethanolamine is the most commonly used. It is usually used in combination with other early strength agents, and the effect of adding it alone is unstable.

Q5

How to choose the right early strength supplement?

Answer: 

The selection of appropriate early strength agent needs to be based on specific project needs and conditions. In addition to considering the early strength effect, it is also necessary to consider its impact on other properties of concrete, such as shrinkage, durability, etc. At the same time, priority should be given to chlorine-free and sulfate-free early strength agents to avoid corrosion of steel bars and impact on the environment.

Q6

What is the difference between early strengthening agent and water reducing agent?

Answer: 

Water-reducing admixtures improve the strength and fluidity of concrete by reducing the water used in concrete mixing, while early-strength admixtures increase the early strength of concrete by accelerating the hardening process. The two work differently, but are sometimes used together for better results.

Q7

What effect does early strength agent have on concrete properties?

Answer: 

Early strength additives have a certain impact on the properties of concrete. For example, some early-strength additives may increase the shrinkage of concrete or cause it to decrease in durability. Therefore, when using early-strength additives, it is necessary to weigh the pros and cons and conduct appropriate mix proportion tests to ensure the stability of concrete properties.
