Features |
1.Water conduction: ：Test according to GB 8076-1997《concrete外加agent》standard. Water reduction rate of Point-I can reach to more than 10%.And it can save 10% cement
2.Improve concrete compressive strength proportion：The Point-Is concrete 3d.7d.28dcan improve 15～25%.20～40%.10～25%.
3.Good workability：Point-I has air-entraining，which can improve concrete's Water resistance, resistance to secrete segregation.
