ZS-Cement Anti-Cracking Admixture

ZS-Cement Anti-Cracking Admixture

1. Product Introduction

What is ZS-Cement Anti-Cracking Admixture?

ZS-Cement Anti-Cracking Admixture is a powder material prepared by adding multiple active ion complex compounds to Portland cement as a carrier. It is added during cement production to produce anti-cracking cement. Concrete made with this anti-cracking cement significantly reduces cracking risk while improving impermeability, compressive strength, and overall durability.

How Does It Work?

Compensating for Shrinkage Deformation: The anti-cracking agent reacts with cement hydration products to generate micro-expansion crystals, offsetting drying shrinkage and autogenous shrinkage during concrete hardening, reducing shrinkage cracks at their source.

Stabilizing Hydration Heat Release: It slows down the concentrated heat release rate of hydration, reducing the temperature difference between the inside and outside of components, effectively inhibiting temperature cracks in mass concrete.

Densifying Internal Structure: It optimizes cement hydration structure, refines capillaries, reduces porosity, and decreases drying shrinkage deformation caused by water evaporation.

Enhancing Tensile Toughness: It improves internal bonding strength of mortar and concrete, increases matrix tensile strength, and effectively prevents micro-crack generation, extension, and expansion.

5. Frequently Asked Questions

Q: What types of cement is this product suitable for?

A: It is suitable for ordinary Portland cement, Portland cement, slag Portland cement, fly ash Portland cement, and composite Portland cement. It can also be used with sulfoaluminate cement. For specialized types, contact our technical team.

Q: How is the optimal dosage determined?

A: Recommended dosage is 600g – 1000g per ton of cement. Exact dosage depends on cement type, target crack resistance, and application conditions. Our technical team can assist with trials.

Q: How should the product be stored?

A: Store in sealed containers in a dry environment. Avoid moisture. Shelf life: 3 months.

Q: What are the main components?

A: The product is a powder material with Portland cement as carrier, combined with active ion complex compounds. It is gray powder, similar in color to ordinary cement, and does not affect concrete workability.
