  • The adaptability of concrete admixture? Seven-step solution! (2)
    The adaptability of concrete admixture? Seven-step solution! (2)
    The third step of the adaptability test is to find out the saturation blending value of the superplasticizer used for this cement. If two or more superplasticizers are mixed, the cement paste is passed through the total amount of the mixture. Test to find the saturation dosage point. The closer the amount of superplasticizer is to the saturated content of the cement, the easier it is to obtain good adaptability.
