It is hot and rainy in summer, in order to guarantee the quality and quantity of concrete supply, Tongya company has taken a series of measures to manage and control concrete configuration, mixing and transportation, so as to effectively cope with the hot weather.  

First of all, optimize the mix ratio design, according to the weather temperature and humidity adjust slump, do a good job of concrete configuration.  Choose cement with lower heat of hydration.  Appropriate admixture with retarder, water reducing agent and other additives, make up for slump loss, to ensure that the quality of concrete products qualified.  

Secondly, the implementation of production indicators, standardize the production process.  For cement, sand, stone and other sunshade treatment, mixing station hopper, water storage device, belt conveyor, mixing building to take shading measures, and sand and stone pile spray cooling, in order to reduce the temperature of raw materials into the mixer.  During the production of mixing, do not add water, as far as possible to shorten the mixing time.  In the meantime, often measure the slump of concrete, adjust the mix of concrete in time ratio, in order to satisfy construction place must slump requirement.  

Third, ensure effective transportation of concrete.  Using concrete transport mixer truck to transport concrete, transport concrete in the process of slow mixing concrete, as far as possible to shorten the transport time, reduce slump loss.  During transportation, do not add water to stir.  

Tongya company strict production requirements, ensure product indicators, high quality concrete production in high temperature weather, to provide guarantee for the efficient construction of each project in summer.
