Shunan Concrete Hardening Accelerator

Shunan Concrete Hardening Accelerator
Product Detailed
1)Strong adaptability to cement 2)Good adhesion stress 3)Weak alkaline,non-toxic/pollution 4)produce efficient accelerativity

Shunan Concrete Accelerator

Shunan concrete accelerator are made from aluminium oxygen and strengthening agent, through the calcining,grinding,modification.This product was recognized as a key popularizing project of scientific and technological achievements in 97 by the ministry of construction, the national association of concrete admixtures listed as the key recommendation new product project. In Beijing, Shanghai, Shenzhen, Tianjin, Xi’an, Hefei, Nanjing, Guizhou, and all over the world,the using performance is better than the congeneric products, praised and dependenced by users.

  

Performance Characteristics:

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.

Second, Technical Indexes

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.

Three, Main 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.

Four, Using method and the Attention:

1. Mixing content is 3 ~ 6% of cement weight, usally 5%,before using, do best dosage and adaptability tests ,according to the engineering requirement and the cement type.

2. For jet concrete, before construction, should mix cement, sand, stone, accelerator with dry mix in proportion, adjust the water cement ratio (0.4 ~ 0.5) immediately jet. Otherwise some materials piled up more than 20 minutes, not only affects injection effect, and can reduce the strength of the sprayed concrete.

3. Poor construction with the product of the agent or unadaptable, need increase the mixing content.

4. When the sand, stone has big water content, should put the accelerator at feed port of concrete sprayer. 

5. This product use plastic woven bag lined with film packaging. Net weight 25 + /-0.25 kg, or according to user needs packaging design. In ventilated dry storage, and may not damp.
