Efficient concrete water reducing agent

　　Efficient concrete water reducing agent

　　1、 Product Introduction

　　This product is a type of β - Qinkuang Sodium Carbamate High Condensation polymer is a non air entraining high-efficiency concrete water reducer with the main component, which does not retard setting, does not air entrain, and has good compactness. It can reduce the Water–cement ratio and greatly improve the early and late strength of concrete. It can be used to prepare high performance concrete and ready mixed concrete with high flow state, high strength, and high permeability This product complies with GB8076-2008 and GB18588-2001 standards.

　　2、 Product performance

　　1. The product has obvious water reducing and dispersing effect, with a water reducing rate of 18% -28%, and can improve the fluidity of cement paste and common mixture under the condition of low Water–cement ratio

　　2. When the Water–cement ratio is kept constant, it can greatly improve the workability of concrete, improve the fluidity of concrete without bleeding and segregation, improve the grip between reinforcement and concrete, and make the concrete surface smooth

　　3. Under the condition of maintaining the original strength, the amount of cement added to the powder is 0 When 5% -1.2%, it can save 15% -25% cement 4. This product has obvious early strength and strengthening effects, with a powder dosage of 0 25% -1.5%, under the same cement dosage and slump conditions, the strength of concrete increases by 50% -120% at 1 day, 40% -100% at 3 days, 30% -80% at 7 days, and 25% -75% at 28 days, with continuous growth in later strength

　　5. This product does not slow down or air entrain, and has a wide adaptability to cement. It can improve the physical and mechanical properties of concrete, reduce the hydration heat of cement, significantly improve the impermeability of concrete, and has no effect on concrete shrinkage

　　6. This product can be used to prepare high-strength concrete with a slump of 5 centimeters to 7 centimeters for C80, and high-strength concrete with a slump of 18 centimeters to 20 centimeters for C60

　　7. High durability concrete, impermeable concrete, and composite use with micro foaming agents can be prepared. High freeze-thaw resistance concrete can be prepared, with a freeze-thaw resistance of over 300 times. High carbonization resistance concrete can also be prepared
