Zhonglv Juneng AFA concrete early-strength antifreeze admixture complies with the JC 475-2004 "Concrete Antifreeze" standard. It contains no sodium salts, potassium salts, or chloride salts, overcoming common issues such as salt efflorescence and moisture absorption in existing concrete. It does not corrode iron parts or steel reinforcement.

I. Product Introduction

AFA concrete early-strength antifreeze admixture is designed and developed for winter construction temperature conditions, commercial concrete pumping, and inhibition of alkali-aggregate reaction. It has low alkali content, accelerates the setting and hardening of concrete under negative temperature conditions, significantly increases strength, and does not affect the development of later strength.

II. Performance Characteristics

Suitable for winter construction at temperatures not lower than -20°C. When AFA early-strength antifreeze admixture is added to concrete according to specifications, it enables the concrete to harden under negative temperatures and achieve sufficient antifreeze strength within the specified time, preventing frost damage to the concrete under negative temperatures.

1. Significantly improves the workability and pumpability of concrete.

2. Functions include antifreeze and early-strength properties.

3. Low alkali content effectively reduces alkali-aggregate reaction in concrete.

4. Good compatibility with various types of cement.

III. Application Range

Chloride-free, it does not cause corrosion to steel reinforcement and can be widely used in winter construction for industrial and civil buildings, roads, bridges, reservoirs, and other structures.

IV. Dosage of Concrete Antifreeze: 4-6% of the weight of cementitious materials
