1. Product introduction of Concrete Hardener
Concrete Hardener, concrete strength, and concrete reinforcement refer to admixtures that can improve the early strength of concrete.
Concrete Hardener's main function is to accelerate the speed of cement hydration and promote concrete strength development. Concrete Hardeners can be widely used in cast-in-place concrete projects, prefabricated components, and concrete projects such as roads, bridges, culverts, and industrial and civil buildings, especially for concrete projects with early strength requirements in winter.
At the same time, the performance of concrete hardener and its normative use is also directly related to the safety and life of the entire project.
2. Advantages and characteristics of Concrete Hardener
The early strength effect is remarkable.
Under the same conditions, the compressive strength of concrete 1d≥125～140%, 3d≥120～130%, compressive concrete strength after seven days≥110%, and the later strength is also improved, and the 28d strength is significantly higher than the benchmark concrete.
Concrete Hardener can shorten the construction period and improve the formwork turnover rate by 30-50%.
Concrete Hardeners can improve the workability of concrete, impermeability, and frost resistance of concrete.
Concrete Hardener is non-toxic, non-flammable, non-corrosive, contains no chlorine salt, and has no rusting effect on steel bars.
3. Application areas of concrete reinforcement
Concrete reinforcement can be widely used in cast-in-place concrete projects, prefabricated components, concrete projects such as roads, bridges, culverts, and industrial and civil buildings, especially in winter or emergency repair concrete projects.
4. How to use concrete reinforcement and matters needing attention
The dosage of concrete reinforcement is 2 to 3% of the cement dosage, and the usual dosage is 2.5%.
The mixing method can be used with the mixing, post-mixing, and multiple addition methods. A commonly used mixing method is mixing the product with cement and then mixing it with aggregate evenly.
Add water and mix; the mixing time is extended to 30-60.
To ensure the quality of the project, it is suggested that the user should refer to the instruction manual for the necessary concrete trial mix when using this product for the first time or changing the cement type.
Please control the concrete's aggregates, water consumption, and admixture amounts to ensure accurate measurement.
If porous aggregate is used in the concrete mixture, it is advisable to add water and stir first and then add the early strength agent.
Concrete reinforcement is best to use mechanical stirring. If manual stirring is used, the mixing time should be appropriately extended to ensure uniform mixing.
This product's vibrating method, transportation, and pouring are identical to ordinary concrete.
Please strengthen maintenance according to relevant standards.
5. Packaging and storage of concrete reinforcement
The packaging specification of concrete reinforcement is 25kg/bag.
Store in a dry and ventilated place.
Pay attention to moisture. The shelf life of this product is one year, and it can only be used after the expiry of the time limit.
This product is valid for 12 months and can continue to be used after passing the concrete test.
6. Product safety instructions for concrete reinforcement
Concrete reinforcement is non-toxic, non-irritating, non-radioactive, non-flammable, and explosive dangerous goods and will not cause corrosion of steel bars.
