④对第一盘拌合物，在出机口和灌注入模口，分别检测其温度和坍落度，确认入

④ For the first tray of mix, check its temperature and slump at the outlet and pouring port respectively, and confirm that the temperature of the concrete mixture entering the mold does not exceed 30°C before construction can continue. <br>⑤ Calculate the slump loss value of concrete during transportation under high temperatures, remind and supervise the on-duty tester, and reserve the slump loss value. <br>⑥ Once the temperature of the concrete mixture is found to exceed the indicator during the construction process, the construction site should be immediately urged to check the cause and take effective cooling measures. <br>⑦After the concrete pouring is completed, check the grouting work of the initially poured concrete and check whether there are shrinkage cracks from the initial setting to the final setting.

④ For the first batch of mixture, the temperature and slump of the concrete mixture shall be tested at the outlet and injection mold mouth respectively, and it shall be confirmed that the temperature of the concrete mixture entering the mold does not exceed 30 ℃ before continuing construction.<br>⑤ Calculate the loss value of concrete slump during transportation at high temperatures, remind and urge duty testers to reserve the loss value of slump.<br>⑥ Once the temperature of the concrete mixture exceeds the target during the construction process, the construction site should be immediately urged to check the cause and take effective cooling measures.<br>⑦ After the completion of concrete pouring, check the plastering and slurry collection work of the initial pouring concrete, and check whether there are shrinkage cracks during the period from initial setting to final setting.

(4) For the first batch of mixture, the temperature and slump of the mixture at the outlet of the machine and pouring into the mould are tested respectively, and the construction can be continued only after the temperature of the concrete mixture injected into the mould is confirmed to be less than 30℃.<br> ⑤ Calculate the loss value of concrete slump in transit at high temperature, remind and urge the operator on duty to reserve the slump loss value.<br> ⑥ Once the temperature of concrete mixture is found to exceed the index during construction, the construction site shall be immediately urged to check the reasons and effective cooling measures shall be taken.<br> ⑦ After the concrete pouring is completed, check the plastering and slurry collection of the initial pouring concrete, and check whether there are shrinkage cracks during the initial setting and final setting.
