Concrete |
So-called concrete is mixed by coordinate performing water,thin aggregate(granulated substance and so on),thick aggregate (gravel and so on) according to the suitable proportion,hardens the nature because of the cement and water chemical properties union along with the date and time growth. |
We request only that the nature of pressure to delivery of no coagulated concretes. Therefore,one-sidedness to quality concrete's view,the standpoint is also different with the concretes or the common concretes'staff.
From now on we must discover two reverse sides to understand that the common characteristic to carry on the pressure to deliver.
Therefore, the concretes which aren't deliveried are regarded that they aren't good immediately,but should request to raise the nature of high pressure to delivery (main construction performance). |
