national defense
water conservancy With the continuous deepening of development, it is now also widely used in precast concrete and other aspects such as shotcrete construction of underground projects and rapid construction of ground cement concrete for plugging leaks and concrete emergency rescue projects.
Features of Second Energy

This series of products has good adaptability to commonly used cement and can be selected according to construction needs.

After use, it has little effect on the later strength of concrete, which is generally

or higher than that of those without it.

The relay is good, the one-time spraying spray arch is larger than
, the side wall is larger than
, less rebound, low dust concentration, and good visibility of the working surface.

Low toxicity
Non-toxic
No pungent odor, no choking when used
Not irritating to the eyes
Does not burn hands.

Fast progress
Low cost
Good impermeability.
Three-use methods and precautions

Before use, it is necessary to conduct adaptability experiments on the optimal variety of cement used in construction and the optimal dosage of this agent.

The recommended dosage is about that of cement


The water-cement ratio should be strictly controlled during construction


< br/> Within the range, excessive water-cement ratio will affect the setting time and use effect.

When the sand and gravel are relatively dry, the sand and gravel
cement
accelerating setting agent can be mixed into a mixture in proportion and sprayed immediately. When the water content of the sand and gravel is large, the accelerating setting agent should be Add at the feeding port of the jet machine, while adding sand
stone
mixture and accelerating the coagulant.

When the working conditions are relatively poor or the cement used for construction has poor adaptability to this product, it may be necessary to increase the dosage appropriately.

The product should be used up once after unpacking. If it cannot be used up, the bag should be tied tightly to prevent moisture, otherwise the use effect will be affected.

The shelf life of the product is
months.
