Hello everyone, welcome! Our news today is for a clearer understanding of that, how much superplasticizer to add.
The appearance of water-reducing agent is divided into liquid and powder; according to the water-reducing and water-increasing ability, it is divided into ordinary water-reducing agent, high-efficiency water-reducing agent and high-performance water-reducing agent.
So that the question is how much superplasticizer to add.
Different types of water-reducing agents have different blending amounts. There are ordinary water reducer and high efficiency water reducer, generally 1%~2%.
1. Water reducer is a concrete admixture that can reduce the water consumption of mixing under the condition of maintaining the slump of concrete.
2. After adding the concrete mixture, it has a dispersion effect on the cement particles, which can improve its workability, reduce the unit water consumption, improve the fluidity of the concrete mixture or reduce the unit cement dosage, and save cement.
The amount of superplasticizer is calculated according to the amount of cement. Therefore, the mix ratio should be determined first, that is, the amount of cement per square concrete should be determined to calculate the amount of superplasticizer more accurately.
In summary, compared with other raw materials, although the amount of superplasticizer is small, it is critical to the quality of concrete. Therefore, during the construction process, the amount of superplasticizer must be strictly controlled and its operation The process should be strictly implemented in accordance with relevant regulations to avoid accidents when configuring the amount of superplasticizer.
At the same time, because the superplasticizer is corrosive when it is configured, if it splashes on the skin, it will have a strong burning sensation, so the relevant personnel should also do their own protective work.
So this is the all information for the news, thank you for your time everyone!
