NNO setretarder superplasticizer is a concrete additive compounded of naphthalene series superplasticizer, aliphatic superplasticizer, amino superplasticizer and setretarder. It is capable of water reducing, retarding the setting, enhancement, improving the flowability and workability of the concrete. It can be used for on-site pumping concrete, mass concrete, road concrete, precast concrete, under water concrete, hydraulic engineering concrete and slipforming concrete etc.
Main features:
1. For concrete works or mass concrete during hot summer, addition of this product can effectively reduce cement hydration heat peak, slow down the release of cement hydration heat so as to retard the hydration and hardening of cement without any negative impact on later strength.
2. Concrete can achieve over 70% of the designed strength after 3 days, and nearly 100% after 7 days. Within 28 days, the strength will still increase to some extent.
3. The mix ratio is 0. 6-1. 5%, water reducing ratio is 14-28%.
Using:
1. Dispensed separately into the cement and mixed well with other admixtures.
2. Wet curing within 7 days after final setting.
