hardening accelerator for concrete

1. Strong adaptability to cement, and the adaptability to five powder or agent is good, but according to the project need chooses to use.

2. Adhesion stress is good, one-time spraying layer thickness (basin arch is more than 10 cm, the wall more than 15 cm)is enough, the springback less, good visibility at working face.

3. Weak alkaline, non-toxic,no pollution. Construction fast and low cost, can save the 15% of construction cost.

4. Blending with other admixture, can produce efficient accelerator, the early strength accelerator, permeabilityreducing and anticorrosive multi-function accelerator.

TECHNICAL DATA

1. The setting time: initial setting 3 ~ 5 min, final set 8 ~ 10 min, the appropriate mix content for cement materials of the amount of 4-6%;

2. Alkali metal content < 1%, non-toxic, tasteless, no exciting;

3. Fine degrees: 8 mm holes screen, screenings less than 10%;

4. Jet concrete early strength is high, the 28 days compressive strength’s keeping rate will to 80-100%;

5. Spraying materials’ cohesiveness is good, no corrosion function to reinforcing bar, increase impermeability label, the quick, a thick layer of spray and spray arch of up to 130 mm, spray wall of up to 200 mm above.

APPLICATION:

Apply to national defense, agent, alley, tunnel, cavity and other underground engineering of jet concrete and injection mortar, the structure of the support from waterproof, prevent leakage, plugging and ground rapid construction of concrete, concrete emergency rescue project.
