What impact will the mixing time of small concrete mixer have on the concrete? Many customers will ask whether to use a small mixer to mix concrete. The longer the mixing time, the more uniform the concrete, the better.

答：不是的，使用小型搅拌机搅拌砂浆水泥混凝土搅拌时间不能过长，搅拌时间过长反倒会影响混凝土质量。

Answer: No, use a small mixer to mix mortar and cement concrete. The mixing time should not be too long. Too long mixing time will affect the quality of concrete.

问：使用小型混凝土搅拌机搅拌混凝土搅拌时间过长会出现什么现象？造成哪些不良影响？

Q: what happens when you use a small concrete mixer to mix concrete for a long time? What are the adverse effects?

答：小型混泥土搅拌机搅拌砂浆水泥混凝土时间过长会造成混凝土混凝土离析现象。当砂浆水泥混凝土混合物出现混凝土离析现象，会严重影响砂浆水泥混凝土混合物使用性能以及质量优劣。

Answer: small concrete mixer mixing mortar and cement concrete for too long will cause concrete segregation. When concrete segregation occurs in mortar cement concrete mixture, it will seriously affect the service performance and quality of mortar cement concrete mixture.

问：什么是混凝土离析现象？

Q: what is concrete segregation?

答：所谓混凝土离析现象是指：由于砂浆水泥混凝土搅拌时间过长会造成，即混凝土胶凝材料（主要为水泥）和骨料（砂石）分离，主要表现为混凝土上层为水泥浆，下层为混凝土骨料。

A: the so-called concrete segregation phenomenon refers to the separation of concrete cementitious materials (mainly cement) and aggregates (sand and gravel) due to the long mixing time of mortar cement concrete, which is mainly manifested in that the upper layer of concrete is cement slurry and the lower layer is concrete aggregate.

当混凝土出现离析现象，混凝土凝结时间很重要，会使得砂浆水泥混凝土失去其应有的作用强度以及混凝土离析表现为粗细骨料分离、大质量颗粒沉积、混凝土泌水等现象的发生。混凝土离析容易造成影响混凝土施工质量，延长混凝土施工时间，降低混凝土结构强度，是建筑施工中混凝土项目不可忽视的问题。

When concrete segregation occurs, concrete setting time is very important, which will make mortar cement concrete lose its due strength, and concrete segregation is manifested as separation of coarse and fine aggregates, deposition of large mass particles, concrete bleeding and so on. Concrete segregation is easy to affect the concrete construction quality, prolong the concrete construction time and reduce the strength of concrete structure, which is a problem that can not be ignored in concrete projects in building construction.
