High Range Water Reducing and Accelerating Admixture
MNC-A1 is a high range water reducing and accelerating admixture. It meets ASTM C 494 requirements for Type C, accelerating, Type E, water-reducing and accelerating and Type F, high range water reducing and accelerating admixtures.
1、It can be applied to normal concrete, reinforced concrete and pre-stressed concrete projects across a wide range of ambient temperature conditions such as mild, low and subfreezing temperatures( above -8℃).
2、It’s compatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash cement and Portland pozzolanic cement etc.
3、It’s suitable for self-cured concrete and its finished products.
4、Concrete mixed with MNC-A1, when cast in a climbing form, can achieve targeted mold-release strength by 10 hours and when cast in a large form, by 24 hours.
Features & Benefits
1、It’s non-toxic, odorless and nonflammable pale powder. It has no corrosion to steel bars.
2、It has remarkable water reducing, strengthening and accelerating effect.
3、Cured at 50℃, concrete mixed with it can achieve 75% of the designed strength grade by 12 hours.
4、When cement consumption and slump remains unchanged, its water reducing rate can reach up to 18%. Concrete compressive strength can be improved by 120% on the 1st day, 80% on the 3rd day and 30% on the 28th day. Under normal curing conditions, concrete mixed with it can achieve designed strength by 3 days.
5、15% of cement can be saved without sacrificing slump retention and strength.
6、It can optimize the cycled use of molds and job site, thus is favorable for fast progress projects.
2.5% of cement quantity.
It can be agitated together with cement. Accurate measurement is essential.
The product is packed in poly woven bag with plastic liens at 40kg.
