High Range Water Reducing and Air Entraining Admixture, MNC-HAJType
MNC-HAJ type high range water reducing and air entrainingadmixture is naphthalene series superplasticizer with air-entraining capacity. It can helpincrease frost and salt resistance, concrete fluidity, concrete plasticity and10% to 20% of flexural strength, as well as decrease bleeding and segregation. Due to thereduced coefficient of concrete thermal diffusion and thermal conductivity, ourproduct has improved the concrete volume stability and weather resistance ofdifferent outdoor structures. Mixed with our air entraining admixture, pumpingconcrete can improve fluidity and pumping pressure.
Our highrange water reducing and air entraining admixture can be used for impermeableconcrete, sulfate-resistant concrete, excessive bleeding of concrete, leanconcrete, concrete for preparation of artificial aggregate, normal concrete,and concrete in high demand for freeze-thaw resistance or facing. Instead ofsteam-cured concrete and prestressed concrete, it isapplicable to concrete which requires high durability, especially frostresistance, in areas such as large dam, airport runway, high-grade concreteroad surface, cooling tower, pool, harbor work and marine structures, etc. Complexed with other admixture, ourproduct can help produce composite additive. Besides, the air-entrainingadmixture is especially used for road concrete, which can not only extend roadlife, but also help sprinkle de-icing salt in northern area.
Dosage and Usage
1. Concrete mixed with ourproduct must be stirred mechanically with more than 3 minutes of stirring time,and its parking time from discharging to pouring should not be too long. Whenusing internal vibrator, vibration time is less than 20 seconds.
2. Recommended dosage is 1% of the weight of cementitious materials.
Package
Ourproduct is packed in woven bag with plastic liner with the net weight of 25 kg each bag.
