Alkali-free accelerating setting agent
r rr
Implementation standard: "Accelerating setting agent for shotcrete"
Product introduction
Alkali-free accelerating setting agent is a powder The concrete mortar admixture has a rapid setting and hardening effect on the cement. The cement slurry mixed with an appropriate amount of accelerating setting agent can quickly set and harden, have high early strength and growing late strength, and can maintain other properties of cement. .
Accelerating setting agents can be widely used in shotcrete and mortar projects. It is used for lining support after rock excavation and ore mining in underground engineering and tunnel engineering in national defense, railway, metallurgy, coal, hydropower and other departments. Compared with ordinary poured concrete support, it can speed up the construction and reduce the project cost.
The alkali-free accelerating setting agent has been certified by the state, and its product performance and comprehensive technical and economic effects are superior to other types of accelerating setting agents.

This agent has the properties of fast It has the properties of fast hardening, strong micro-expansion and other properties.
Using alkali-free accelerating setting agent, it has fast setting, high viscosity, small rebound, wide adjustment range and strong adaptability to cement.
Initial setting time, final setting time.
The dosage is % of the cement dosage, and the water-cement ratio is.
The compressive strength after adding this agent in one day is 0.0%, and the strength can be maintained at more than % without adding this agent.
The cement setting time is greatly affected by the temperature, which is lower than ℃ (generally the temperature is ℃), so the dosage can be increased appropriately.
Packaging and storage
