(1)混凝土滞后泌水与普通泌水机理上有何区别?混凝土泌水由于材料质量和过程控制的疏忽,泌水极易出现,发生泌水的混凝土常常伴随着离析状态,两者几乎是同时出现的,由于骨料粘结力的松散,出现沉降等问题,给初期的混凝土造成缺陷,如果是平面结构会给施工工艺造成很大的难度,竖向结构的流砂、水痕等等都给混凝土造成外观缺陷;普通的混凝土泌水一般在出机后取样就能观察得到,只要及时
(1) What is the difference between lagging concrete bleeding and common bleeding mechanism? Because of the material quality and process control negligence, bleeding is very easy to occur. The bleeding concrete is often accompanied by segregation, which is almost At the same time, due to the loose aggregate adhesion, settlement and other issues, the initial defects caused by the concrete, if the plane structure will cause great difficulty to the construction process, the vertical structure of sand, water marks and so on The appearance of defects caused by concrete; ordinary concrete bleeding usually after sampling can be observed, as long as timely
