3.3运送至浇捣地点的混凝土坍落应当符合要求，当出现离析情况时，进行二

3.3 transported to the pouring site shall meet the requirements of concrete slump, when segregation occurs, secondary mixing, stirring time is determined by experiment. It has been forbidden to transport to any location concreting with water. <br><br>3.4 from the stirring, transportation, pouring into the mold, the temperature is not higher than 25 ℃, duration of not more than 90min, when the temperature is higher than 25 ℃, should not be greater than the duration of 60min. When the admixture or admixtures used in hydraulic cement concrete is rapid, the duration should be determined by experiment

3.3 The concrete collapse delivered to the pouring site shall meet the requirements, and when the separation situation occurs, a secondary stirring shall be carried out, and the stirring time shall be determined by the experiment. It is strictly prohibited to add water to concrete that has been transported to the pouring site.<br><br>3.4 From stirring, transporting to pouring into the mold, the temperature is not higher than 25 degrees C, the duration is not greater than 90min, when the temperature is higher than 25 degrees C, the duration should not be greater than 60min. When an admixtureis is added to concrete or fast hard cement is used, the duration should be determined by experiment

3.3 the concrete slump transported to the place of pouring and vibrating shall meet the requirements. In case of segregation, secondary mixing shall be carried out, and the mixing time shall be determined by the experiment. It is strictly forbidden to add water to the concrete that has been transported to the pouring site.<br>3.4 from mixing, transportation to pouring into the formwork, when the temperature is not higher than 25 ℃, the duration shall not be greater than 90min; when the temperature is higher than 25 ℃, the duration shall not be greater than 60min. When admixtures are added to the concrete or quick hardening cement is used, the duration shall be determined by experiment<br>
