Desc:In the historical construction and construction engineering systems, the production and application of early strength agents are relatively extensive. At present, my country's use of early strength agents and early strength water reducing agents is also hundreds of thousands of tons. However, with the deepening of people's understanding of the potential harm of chloride ions, sulfate ions and alkali metal ions on the performance and long-term stability of concrete, calcium formate early strength agent can not only play a good early strength effect, but also avoid The advantages of some early strength components causing corrosion of steel reinforcement in concrete have been recognized.
