Guotai Junan released a research report saying that under the background of carbon neutrality, the scarcity of coal mines is prominent, and the value of assets will continue to increase. The high point of capital expenditure in the coal industry appeared in 2012. Under the general direction of carbon neutrality, the overall investment in the industry has slowed down, and capital expenditure has gradually declined. From 2021 to now, the Energy Bureau of the National Development and Reform Commission has only newly approved 17.4 million tons of 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

The COVID-19 pandemic has affected economies and chemical companies in many countries around the world. Measures such as extending holidays and resuming work were taken to control the development of the epidemic, and the normal operation of some chemical enterprises was also affected to some extent.
We provides high quality early strength agent with reasonable price. “In order to feedback to old customers, the company is still in full operations to provide early strength agent with competitive price.” said Olina, the sales manager.
