Alkali-free solid setting agent product manual Alkali-free setting agent is a new type of environmentally friendly alkali-free, chlorine-free high-performance setting agent developed by our company. It has a strong function of accelerating cement solidification, and can also greatly improve the early and late cement strength, as well as improve the anti-seepage ability. Alkali-free solid setting agent product manual Product introduction: Alkali-free setting agent is a new type of environmentally friendly alkali-free, chlorine-free high-performance setting agent developed by our company. It has a strong function of accelerating cement solidification, and can also greatly improve the early and late cement strength, as well as improve the anti-seepage ability. Ingredients: This product is an alkali-free quick-setting agent product of aluminum sulfate system, which is non-toxic, harmless, non-radioactive, non-corrosive, non-flammable and non-explosive. Safety tips: Avoid contact with skin and glasses; if contact occurs, rinse with clean water. If splashed into eyes, wash with plenty of clean water or seek medical attention. Wear a mask and goggles when contacting powdered products. Storage conditions: The inner and outer packaging bags of instant powder should be intact to prevent water absorption and moisture. After being prepared into liquid, the storage temperature should be greater than 5ºC. Liquid finished products should be stored in plastic/glass fiber reinforced plastic barrels. The pH value of this product is weakly acidic and will react chemically with steel materials. Avoid using iron barrels for storage. Storage time: Instant powder products can be stored in a sealed state for 2 years, and can be stored for 3 months after being prepared into liquid. If the liquid product has a long storage time, it is recommended to stir it simply when using it to eliminate the visual micro-stratification phenomenon. Product packaging:  powdered alkali-free quick-setting agent is packaged in 25Kg plastic woven bags or ton bags, and can also be customized according to customer requirements.

Application

 

 

1.Suitable for all kinds of shotcrete and mortar. Powder is used for dry shotcrete, liquid is used for wet shotcrete.

2. Suitable for spraying concrete in railway tunnel, highway tunnel and subway project.

3. Suitable for anchor shotcrete in diversion tunnel of hydropower project.

4. Quick-setting concrete and mortar used for rush repair in mining and construction engineering.
 

Usage & Notice

 

 

1. Before using the accelerator, the setting time experiment should be carried out with the cement used in the project to determine the optimal dosage. (test method is: take 400g cement, according to the water-cement ratio 0.4 add water (liquid contains water in accelerating agent), stir evenly after adding the production Product, quickly stir 25-30s to install the mold, measure the condensation time).

2. After mixing the concrete into the jet, add accelerating agent at the jet. Water-binder ratio: mortar 0.35-0.40, concrete 0.38-0.44, the ejecta does not flow, dry spots, uniform color is appropriate.

3. It is required to use no less than 42.5 Portland cement and ordinary Portland cement.

4. The shrinkage of concrete mixed with accelerating agent is greater than that of concrete not mixed with accelerating agent, so curing needs to be started within 4 hours of spraying. Curing time is not less than 1 week.

5. GQ-SN03 alkali free accelerating admixture , there is a little clear liquid on the upper part after a long time, which is a normal phenomenon and needs to be treated before use

It does not affect the normal performance when used after shaking.
