·No need to use sand ash, fly ash, strong plastic agent, water reducer, expansion agent and other additives.

·Accelerator and gas transmission agent can be added to meet the needs of the project.

·Generally do not allow curing agent: when the temperature is too high, only a small amount of water spray curing can be done once or twice.

·After mixing for 3-4 hours, the slump loss is still very small.

·No bleeding, not easy to precipitate, excellent bonding force.

·The cement mortar is milky and its slump is controlled to 5-10 cm, but it has good workability and is easy to be vibrated and leveled.

·In high pressure shotcreting operation, it is easy to pump and transport, the vibration of the conveying pipe is small, and it is not easy to plug the pipe

·The thickness of each pass of high pressure shotcreting can reach 7-8 cm, and the rebound amount is less than 5%.

·The construction temperature is - 5-40 ℃, but does not affect the setting time.

·Milk like cement paste can increase the construction time, but does not affect the setting time.

·It is about 200-300 microstrains, and it has crack resistance.
