Concrete Admixture Plastic Expansion Agent Anti-Cracking and Anti-Shrinkage

Product Description

Product Description

Plastic expansion agent is a kind of additive specially used in materials such as compression mortar and grout, which can produce micro-expansion in the plastic phase to compensate for the shrinkage in the plastic phase. Its main function is to avoid settlement and cracking of concrete mortar and to ensure that concrete mortar is dense and full.

Functions:

1. Prevent settlement and cracking: Plastic expanders can produce micro-expansion in the mortar, effectively preventing the settlement and cracking of concrete mortar and ensuring dense and full concrete.
2. Improvement of durability: By compensating for shrinkage, it improves the durability of concrete, especially in wet environments, and can play the role of anti-seepage.
3. Environmental performance: plastic expansion agent is non-toxic, non-odor, friendly to the environment, and the generation of mainly nitrogen, no corrosion and no damage to concrete reinforcement.

EP-2
Grouting material Plastic expansion agent

EP-2 is a new plastic expansion agent developed for high-strength non-shrinkage grout, compression grout, concrete and so on. It solves the problem that the plastic expansion agent expands too early, resulting in low effective expansion value. EP-2 is a new plastic expansion agent developed for high-strength non-shrinkage grout, compression grout, concrete and so on. It solves the problem that the plastic expansion agent expands too early, resulting in low effective expansion value. The expansion principle of plastic expansion agent: it slowly produces bubbles according to the hydration of cement, resists the shrinkage caused by hydration, and achieves the expansion effect. 1. The initial foaming time is about 20 minutes, before the initial setting. It does not affect the strength 2. The amount added is about 2-300 grams 3. The expansion rate is added 500 grams. The expansion rate can reach 1,000 meshes, about 1,100 meshes, and the gas generated is nitrogen

Product characteristics

EP-2 has good dispersion and workability.
 

1. Plastic expansion function before hardening: before hardening, the plastic expansion agent can make the material in the plastic state not only does not settle and shrink, but also produce a small amount of expansion, and keep it until hardening.
2. Water-soluble aerated material: it produces plastic expansion after dissolution, which solves the deficiency of solid aerated material.
3. Good adaptability of admixtures: does not affect the setting time, does not contain chloride no corrosion of steel, no irritating odor.
4. Low dosage: formation of uniform and dense bubble holes, early expansion is obvious, expansion lasts for a long time.

Technical Data

Appearance	yellow powder
Water content	≤3%

Recommended dosage:In practical application, the type and dosage of expansion agent can be selected and adjusted according to specific needs. For example, the appropriate dosage of plastic expansion agent in grout is 0.05-0.1%, but the optimal dosage should be adjusted according to the test results.
 

Scope of application

1. Grouting agent: Appropriate dosage in grouting agent can effectively prevent settlement and cracking, and improve the compactness and fullness of grouting agent;
2. Grouting material: the use of plastic expansion agent in grouting material can compensate for the shrinkage in the grouting process and ensure the compactness and fullness of grouting material;
3. Construction: In construction projects, plastic expansion agent can improve the seepage resistance and durability of concrete, applicable to underground buildings, pools and other projects that require seepage control.

Usage and Precautions

1. When using, need to be mixed with other dry powder components together, when using according to the construction of different areas of mixing requirements for mixing and construction;
2. The recommended dosage is 0.05-1% dosage, and the specific dosage is determined by trial mixing according to the application system and the change of dry mix components;
3. The mixing amount of concrete with higher requirements for freeze-thaw resistance and winter construction concrete should be determined by test according to the requirements of air content of concrete.
4. The air-entraining quantity is affected by the material used to formulate concrete and the temperature of the environment in which the concrete is prepared, so it must be kept as stable as possible in order to control the fluctuation of air content.

 

packaging and storage

1. Packed in paper-plastic composite bag, 25kg/bag, the storage period is 12 months from the date of production, if it exceeds the shelf life, it must be verified by test and inspection before use;
2. Place in a ventilated and dry place for storage, pay attention to moisture-proof treatment, avoid direct sunlight, use it in time after opening, and seal it in time if it is not used up to prevent moisture absorption and deterioration.
