Adaptability is also known as compatibility ( compatibility ). This can be a qualitative understanding of the concept: in accordance with the adaptability of concrete admixture, the inspection in accordance with the relevant standard of the admixture is added to the set to use the variety of admixture of cement concrete, if can produce due effect, we say that the cement and the additive is adapted to; conversely, if the cannot produce due effect, we say that the cement and admixture between does not adapt to the.
On admixture and cement between adaptation and not, cannot currently be expressed quantitatively, mostly to cement system, mixed with some functional additives, can achieve the expected results to adapt to it or not.
On water reducing agent, after according to the standard test of qualified products, can be at the same water condition, increase the fluidity of concrete or concrete; while maintaining identical mobility situations, concrete to reduce both consumption. But in the practical application, the same water-reducing agent in some cement system, commonly used in dosage, can usually water-reducing rate; but in some other cement system, to achieve the water reducing rate, then the water reducing agent to increase a lot, and sometimes even in its volume increases 50% above, still can't achieve its water reduction rate. And, the same water-reducing agent in some cement system, in the cement and water contact after 60 ~ 90 minutes of high slump can still remain, and there is no segregation and bleeding phenomenon; in other cases, the existence of different level land slump loss problem of fast. When we say: the former, water-reducing agent and cement are adapted to, the latter is not adapt to the. In addition, the same kind of cement, when using different manufacturers of the same type water reducing agent, even if the water cement ratio and content of water-reducing agent, also can appear significantly different effects. This explains the cement and superplasticizer exists between the adaptability problem.
