This product has passed China's compulsory product certification audit and is a 3C certified product.

1. Product features:

This product has the characteristics of anti-freeze, reinforcement, water reduction, low alkali, chlorine-free, and easy to use.

2. Purpose:

Used for concrete projects constructed under the daily minimum temperature of -5℃, -10℃, -15℃ or mortar projects and highways constructed under negative temperatures. , bridges, water conservancy, civil construction, unfired bricks, prefabricated components, indoor concrete, etc.

3. Dosage and usage:

1. Within a certain range, the optimal dosage of JH-I early-strength antifreeze water-reducing agent should be adjusted according to temperature changes, taking into account the air height and For economical use, a dosage of 3-5% is appropriate. The optimal dosage can also be adjusted based on the trial mix.

2. Before preparing concrete and mortar at a lower temperature, rinse the mixer with hot water or steam. First add sand, gravel and hot water and stir for 1 minute, then add cement and antifreeze and stir for 3 minutes. The temperature of the mixing water should be adjusted according to the time to ensure that the temperature of the concrete entering the mold is ≥10°C. After pouring the concrete, it should be covered with heat preservation in time.

3. Minimize water consumption while ensuring normal construction workability; because the amount of free water in concrete increases, the frost resistance performance decreases significantly. The concrete mixture mixed with antifreeze has the characteristics of dry but not hard. Pay attention to control the slump of the newly poured concrete not to be too large.

4. Sand and stones should be covered with canvas or plastic sheeting to prevent the sand and stones from freezing. The cement must not be heated directly and should be transported to a greenhouse for storage one day before use to keep it at a positive temperature.

5. Before pouring concrete, ice, snow and dirt should be removed from the formwork and steel bars. However, steam must not be used to melt ice and snow directly to avoid freezing again. Timely remove the concrete residue adhering to the container and remove the ice, snow and frozen blocks in time. The container must be tightly covered after use to keep it warm. The exposed surface of newly poured concrete should be covered with plastic film and insulation materials in time, and cured under negative temperature conditions. The concrete should not be watered. Work continuously according to the principle of pouring, vibrating and covering.

6. The cement should be Portland cement or ordinary Portland cement with a strength grade of 32.5 or above. The sand and stones must be clean and must not contain ice, snow and other frozen materials, as well as substances and oils that are easy to freeze and crack.

7. If this agent becomes damp and clumps, it should be discarded and not used.

4. Storage and packaging:

1. Packaging: using Packed in woven bags lined with plastic bags, net weight per bag is 50kg, liquid per barrel is 230±2kg.

2. Pay attention to moisture-proof and damage-proof. The product should be placed in a dry and ventilated place to prevent moisture and caking. The storage period is two years.
