一、UNF—2型高效减水剂它是一种高效非引气性萘系减水剂。掺加少量这种减水荊,就能增大混凝土坍落度,减少用水量,提高早期及后期抗压、抗折、抗拉强度,提高弹性模量、抗渗性、耐水性。掺入量一般为水泥重量的0.5～0.7%,可节约水泥10～20%。该减水剂对矿渣水泥、普通水泥、火山灰水泥都有效。对自然养 First, UNF-2 type superplasticizer It is a highly effective non-air-entraining naphthalene superplasticizer. Adding a small amount of this water reducing agent can increase concrete slump, reduce water consumption, improve early and late pressure resistance, flexural resistance, tensile strength, and improve elastic modulus, impermeability, and water resistance. The blending amount is generally 0.5 to 0.7% of the cement weight, which can save 10 to 20% of cement. The water reducing agent is effective for slag cement, ordinary cement, and pozzolanic cement.
