| Abstract: | Through the incorporation of composite antifreeze,in a large number of concrete test basis,adjustment"pre-raising time" and with reference to JC 475—2004 "Concrete antifreeze" to develop quality evaluation methods antifreeze compound in the pre-raising time.Which gives the compound antifreeze quality assessment methods,to fill the gap,to provide for the assessment based on winter construction. |
