1、体 积 混 凝 土 测Ill一、测温结果应在以下范围中才使砼不易产生裂缝：1. 混凝土浇筑体在入模温度基础上的温升值不宜大于 50C；2. 混凝土浇筑块体的里表温差不宜大于 25C；3. 混凝土浇筑体的降温速率不宜大于 2.0C/d；4. 混凝土浇筑体表面与大气温差不宜大于 20C。二、根据混凝土浇注时温度变化的特点，系统设备作以下配置，一台建筑 电子测温仪(JDC-2)。三、入模测温，每台班不少于 2 次。配备专职测温人员，按两班考虑，对测 温人员要进行培训和技术交底。测温人员要认真负责，按时按孔测温，前 3 天 每2 小时测温 1次，每昼夜不得少于4次，不得遗漏或弄虚作假。测温记录要 填写
2、清楚、整洁，换班时要进行交底。四、测温时发现温度异常，应及时通知技术部门和项目技术负责人，以便 及时采取相应措施。五、测温组共分三组，每组三个测点，三个测点分别为底：距底部100 150MM；中：在浇筑厚度的中部；表：在距浇筑表面100150MM部位。具体位 置见下面测点平面布置图片。IR I I 1 I i I I II I I V I E E F 1 I大体积混凝土结构测温记录工程名称华侨城天鹅堡一期东区结构部位 1-、楼主楼及群房基础筏板砼强度等级C35P微膨胀配合比编号SXPB-2011-068 砼数量)1130砼浇灌日期20年7月1日砼浇灌温度29.7开始养护温度34测温时间各测点温
