Concrete Retarding Admixtures

MNC-BS

 

Description

MNC-BS is made of selected corn starch and is a commonly used retarding agent in construction materials.
MNC-BS is suitable for high temperature, long haul, and pumping concreting. It’s also applied in mass concrete, self-leveling concrete and high strength concrete.It complies with ASTM C 494, Type B.

Typical Advantages

• High workability, no segregation, no water bleeding.
• Improve the concrete breaking strength, tensile strength, elastic modulus and adhesiveness to the steel bar.
• Improve concrete durability performance, such as anti-seepage, anti-freezing and anti-carbonization.
• Avoid cement initial hydration, extending cement and concrete setting and retaining time.
• Non-toxicity, non-inflammable, non-corrosion to the steel bar.

Application range

It’s widely applied in concrete requiring extended setting time, mould concrete and mass casting concrete.
It can be applied as a retarding component for producing retarding superplasticizer.
Compatible with Naphthalene Superplasticizer, Amino Sulfuric Acid Superplasticizer and Air-entraining Agent.

Typical Properties

Package, Storage & Handling
