Sodium High Range Water Reducing Admixture - TD18

Introduction

Retarding superplasticizer is brownish gray powder (agent of brown liquid), it is in the naphthalene sulfonate formaldehyde condensates with on the basis of modifiers, enhancers and other additives formulated with water reduction high, retarding, and reinforcing effects, etc., through the reduction of water, dense, crystal structure and other effects to improve the cement to improve concrete (mortar) strength, impermeability, durability and other properties, this product is non-toxic, tasteless, no corrosion of steel.

performation

1, powder dosage of cement weight 0.6-1.5%; liquid dosage is 0.8-2% by weight of cement.
2, water reducing rate of up to 10-20%.
3, concrete slump may be increased as compared with the reference concrete more than doubled.
4,concrete setting time may be extended for 1-4 hours, and can reduce the initial heat of hydration of cement hydration heat and delayed peak time.
5, concrete compressive strength 3 days, 7 days, 28 days can be increased about 15%.
6, while maintaining the strength and slump of concrete under the same conditions can save 8-12% cement.
7, can improve the impermeability of concrete, freeze-thaw resistance and durability.
8, no chlorine ions, no corrosion of steel.

scope of application

For a variety of in-situ and precast concrete, reinforced concrete; strength, high strength and medium strength concrete, and high fluidity concrete. Can be used for daily minimum temperature above 10 °C concrete. Can be used for a variety of pre-fabricated and cast, reinforced, prestressed concrete.
Large formwork construction, sliding construction. Large volume, pumping, flowing concrete

feature

Less water enhancement, improved workability, saving cement, adaptable

precautions

Changes in the cement varieties or new cement, concrete compatibility testing should be done; in combination with other additives, should first examine its compatibility; must mix the correct ingredients, pouring concrete construction in strict accordance with standard operation; powder products during the warranty period, in case of damp agglomeration, can still be used after sifting through the ground
