- 摘要:
- 在大庆200MW火电厂锅炉等设备基础的大体积混凝土施工过程中，通过严格执行模板设置、混凝土的搅拌、输送、振捣、养护等工艺规范，采取定时定位监测凝结水化热的温度等工艺措施，有效地控制了大体积混凝土浇筑后可能产生的裂纹。
During the construction of larae volume concrete for the foundation of boilers in Daqing 200 MW thermal power plant, by strictly following the codes for arraopmet of mould plates, for mixing,transportation, tamping and curing of conrete, and by taking the technological measures such as monitoring and measuring the heat of hydration at fixed ponts and times, the cracks would possibly occur after casting of large volume concrete were effectively controlled.1996,2(2): 28-30分类号：TU755
