Handan Chenghao Co., Ltd.
Sodium lignosulfonate water-reducing agent
The product complies with the national standards for concrete admixtures
This product is modified sodium lignosulfonate, which is powdery and has low air-entraining properties. Retarding water reducing agent is an anionic surface active substance that has adsorption and dispersion effects on cement and can improve various physical properties of concrete. It can be compounded into early strength agent, retardant, antifreeze agent, pumping agent, etc. The liquid admixture made after compounding with naphthalene series high-efficiency water reducing agent has basically no precipitation.
Main performance:
The dosage of sodium lignosulfonate water-reducing agent is .3 of the cement dosage. The commonly used dosage is . Compared with the 3-day intensity improvement, the day-to-day intensity has improved, the day-to-day intensity has improved-, and the long-term intensity has also increased.
.
It can increase the fluidity of concrete and improve workability without changing the water consumption of concrete.
3.
While maintaining the slump and strength of the concrete at the same level as the benchmark concrete, - tons of cement can be saved. Using tons of sodium lignosulfonate water-reducing agent powder can save 3-tons of cement.
.
Under standard conditions, compared with the benchmark concrete, the concrete mixed with this agent can delay the initial setting time of concrete by more than 3 hours, the final setting time by 3 hours, and the peak of hydration heat can be delayed by more than 1 hour, which is beneficial to Summer construction and transportation of commercial concrete and large-volume concrete projects.
.
Sodium lignosulfonate water-reducing agent has slight air-entraining properties and can improve the anti-penetration freeze-thaw performance of concrete.
. This agent is non-corrosive to steel bars and aggregates after being mixed into concrete.
Scope of application
This product is suitable for large volume concrete, large fluidity concrete, pumped concrete, commercial concrete and summer concrete construction as well as concrete with special requirements for retardation, cast-in-place pile concrete, and immersed pipe piles Concrete, manually dug pile concrete and underground mass concrete construction have good economic benefits.
How to use
.
The dosage is .3 of the cement weight, the recommended dosage is .
Powder can be added directly to cement, sand, and gravel for dry mixing. After uniformity, add water for mixing. The mixing time should be appropriately extended to avoid uneven mixing. The powder can be pre-prepared with a certain concentration of solution and added in the form of aqueous agent, but it should be deducted from the total water consumption of the concrete.
3. When using this product, please refer to this instruction to conduct the necessary concrete mix proportion test according to the specific construction conditions (construction season, engineering materials, etc.) to obtain the best use effect.
Packaging, storage and transportation
.
This product is a powder. It is packaged in a woven bag with an auxiliary film on the outside and a plastic bag on the inside. Each bag is heavy.
.
This product is valid for one year and can continue to be used after passing the concrete test.
3.
