Concrete Early Strength Agent

Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China.  For China, we should keep to the dynamic zero-out and gradually open up."  

However, "dynamic zero clearance" is not the pursuit of complete "zero infection".  As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.  

The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy.  The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.  

As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many early strength agent.

Overview of concrete early strength agent:

Concrete early-strength agent can greatly change the final setting time while ensuring the quality of concrete is reduced. It is changed to demoulding as soon as possible. The sleeve accelerates the turnover of the formwork, saves the amount of formwork, saves energy and saves cement, reduces production costs, and improves the output of concrete products.

Our early strength agent 31B can reduce the activation energy of the cement hydration reaction, increase the hydration reaction rate, promote the rapid development of the strength 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) 31B does not contain chlorine ions and has no rusting effect on steel bars. It is suitable for all civil, industrial buildings and prestressed reinforced concrete members, mortar, etc.

(2) 31B is suitable for construction under low temperature in early winter and early spring;

(3) 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 early strength performance, can greatly improve the strength development under normal temperature, low temperature or thermal curing temperature conditions

2. It can improve the durability of cement mortar and board, and won't shrink the strength of cement mortar and board.

3. Shorten demolding time and speed up mold turnover

4. Shorten or even eliminate steam curing process, save energy and reduce consumption

5.Reduce the amount of glue


Package of concrete Early strength agent:

25kg/bag

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.
Add amount:2-4 kg/m3
Appearance: Grey powder
Application: The main function of early strength agent is to accelerate the hydration speed of cement and promote the development of early strength of cement.

The resurgence of the global COVID-19 pandemic and the impact of the Russia-Ukraine conflict continued to cause high volatility in commodity prices. Stubbornly high inflation and rising commodity prices are likely to influence each other and thus push each other higher. The price of the early strength agent may not decrease significantly in the short term.
