Construction quality control for summer and precautions

Summer is the year continuous high temperature, more complex changes confront a season; hot summer,

large evaporation of water, fresh concrete appears dry fast (surface), setting speed, false condensate,

condensate duration, lower intensity, etc., and will bring crack phenomenon, which affects the quality

of concrete.

 

In the hot season, the higher the temperature, the higher the temperature of the concrete machine,

concrete cement hydration the faster, reducing the construction of its properties, such as the slump

loss is too large, it can not guarantee that construction; setting time is short too late to receive

light; coupled with temperature can cause cracks, shrinkage cracks and other series of quality problems,

the concrete temperature control is particularly important in summer, the other is to delay the rate of

hydration of cement, reduce early hydration heat of concrete.
