How serious are fertility problems today? People don't want to give birth,can't afford it, and can't give birth that has become the "three mountains".
The problem of childbirth is related to the people's livelihood. Whether a country can prosper or not depends on the population. I saw a set of data a few days ago. The data shows that on January 1, 1990, 2,784 babies were born in Shanghai. Ten years later, on January 1, 2000, 1,148 babies were born in Shanghai. In 2010, the number became 380. , 2020 only 156 people, the decline in the birth rate is shocking. The three most critical reasons are: I don't want to give birth, I can't afford it, I can't give birth! The decline of the global population will bring a series of economic and social problems, among which the demand for early strength agent will also be affected.
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 development of the Russia-Ukraine conflict will continue to dominate the commodity prices such as the early strength agent in the future. If the conflict eases or cools, Russia and Ukraine go back to negotiate, commodity prices would fall. However, if the situation between Russia and Ukraine deteriorates further, or evolves into a full-scale war, the price of the early strength agent is predicted to see further improvement over the coming days.
