How to cool the aerated concrete block in summer

For aerated concrete block,the cooling problem has a direct relationship with its quality,in this text,Zhengzhou Boiler Co., Ltd,as a professional autoclave manufacturer in China,will give the following advices about cooling the aerated concrete block in summer.

Cooling the concrete mixing water

In summer,we can cool the the concrete by cooling the mixing water,the biggest drop of concrete temperature can reach 6 ℃ by using this method.We can use the heat pump technology to cool the mixing water,the heat pump can heat or cool the aerated concrete.

Using the liquid nitrogen to cool the mixed concrete

Injecting the liquid nitrogen into the mixed concrete is an effective method to reduce the temperature of concrete,in the process of cooling,the liquid nitrogen should be supplemented timely,generally,it needs 48 cubic meters of liquid nitrogen to reduce 0.5 degrees of concrete temperature.

Cooling the coarse aggregate

Because the coarse aggregate takes a large proportion in the aerated concrete mixing process,cooling the coarse aggregate can reduce the temperature of concrete.The effective method of cooling the coarse aggregate is using cold water to spray or using plenty of water to rinse.

In addition to the above three methods,we can also replace part of the mixing water with ice to cool the aerated concrete blocks.Zhengzhou Boiler Co., Ltd,as an experienced autoclave manufacturer,can provide many reliable autoclaves for aerated concrete block and professional advices about the aerated concrete block,please contact us for more details!
