| 摘 要： | 普通混凝土的强度与水灰比的大小成线性关系．在混凝土施工中，实验室出具的配合比为理论配合比，即砂、石在干燥状态下的配合比；但是，实际施工中，砂、石的含水量是随气候的变化而变化的．如何控制好水灰比,保证混凝土施工质量?章介绍了施工中混凝土配合比的调整方法，以期确保混凝土在施工中的质量．

| Abstract: | The intensity of normal concrete is linear relationship with th e size of water cement ratio. In the construction of concrete, the mixture ratio which the testing laboratory provides is the design mixture ratio: the sand an d stone are in the drying condition. But in actual construction, the water con tent of sand and stone will change with the changing of climate. How to control the water cement ratio and guarantee the concrete's quality? The paper introduce s the adjustment method of the concrete's mixture ratio to guarantee the concret e's quality. |
