TZN-2 high-range water reducing admixture is a purification product based on TZN-1high-range water reducing. The Na2SO4 content is less than 5%. It has the performances of non-air-entraining, high-range water reducing and strengthening effects. It is in particular suitable to produce concrete with the requirement of high water reduction, high-early strength and high-anti-filtration or vapor-cured. It can also be used as the water-reducing gradient of composite concrete admixtures. TZN-2 is formulated to comply with GB8076-1997.
MAIN TECHNICAL PROPERTIES
1、 The normal range of TZN-1 addition rate is 0.5~1.2% by weight of cementitious materials. The water reduction rate can be reach to 15%~ 30%.
2、 Comparing with ordinary concrete, the strength of concrete with TZN-1at the age of one day can be improved by 50%~100%, at the age of 3 days can be improved by 40%~80%, at the age of 7 days can be improved by 30%~80%, at the age of 28 days can be improved by 25%~75%, at the age of 90 days can be improved by 10%~50%.
3. Widely used in pre-cast & ready-mixed concrete, armored concrete and pre-stressed reinforced concrete in key construction projects such as dam and port construction, road building & town planning projects and dwelling erections etc.
4、 Suitable for preparation of early-strength, high-strength, high-anti-filtration and self-sealing& pumpable concrete.
1、Addition rate：The normal range of TZN-2 addition rate is 0.5-0.8% by weight of cementitious material.
2、Direct use of powdery agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio:60%).
PACKAGING and STORAGE
TZN-2 is packaged in anti-wetting double-layer plastic bags with the weight of 50kg per bag, and is easy to be delivered and transported. It should be stored in dry place. Its quality guarantee is within two years.
