| Abstract: | This text enters the demand (not greater than 28 degrees Centigrade ) for the temperature of the moulding concrete in the Subway Line No.5 project of Beijing at heat season,entering factory's temperature control through the raw materials,optimization of mix proportion design of concrete,scientific dispatcher,such measures as construction,etc.of trying to avoid high-temperature time slot,under staying supervision,concrete producing temperature of outof-machine and temperature lose can be reduced to meet the construction demand. |
