Dedicated Additive For Road

DH dedicated additive for road is a new type of concrete additive dedicated to tight-scheduled road repair and construction. It not only reduces cement content, avoids cracking, enhances the durability, but also remarkably increases compressive strength and bending strength. With it, the construction duration can be shortened and the road can be open to traffic ahead of schedule.
Types:
1. NNO-1d(open to traffic in 1 day ): mix ratio is 1. 8-2. 0%, water reducing ratio is 19-25%.
2. NNO-3d(open to traffic in 3 days): mix ratio is 1. 6-1. 8%, water reducing ratio is 18-21%.
3. MZS high-efficiency hardening accelerating and water reducing additive(open to traffic in 7 days): mix ratio is 0. 8-1. 2%, water reducing ratio is 10-12%.

Using:
1. Care should be taken to water reducing and the slump be controlled within 0-3cm.
2. DO NOT add water at random.
3. Dispensed into the cement and fully mixed, the mixing time should be prolonged for 1 minute.
