我国目前正处于飞速发展的阶段,随着人民的生活需要,高层建筑日益增多。高层建筑的施工,大多数离不开混凝土的浇筑,在混凝土的浇筑过程中,有可能出现这样那样的问题,例如:泌水、和易性差、板结等现象,影响工程质量和进度。对于这些问题如何处理,主要从以下三个方面分析。1混凝土泌水、离析问题浇筑过程导致混凝土泌水、离析现象很多,原材质量、混凝土配比使用、生产过程控制都会引起此类问题,主要包括:砂子细度模数过大、颗粒级配不均匀、
At present, China is in a stage of rapid development. With the needs of people’s lives, there are increasing high-rise buildings. The construction of high-rise buildings, most of them are inseparable from the concrete pouring, concrete pouring process, there may be such problems, such as: bleeding, poor workability, plate knot and so on, affecting the quality and progress of the project. How to deal with these problems, mainly from the following three aspects. 1 Concrete bleeding, segregation problems The pouring process leads to concrete bleeding, segregation phenomenon, the quality of raw materials, the use of concrete ratio, the production process control will cause such problems, including: sand fineness module is too large, the particle size distribution Uneven,
