对粉煤灰，这一水胶比界限约为0 . 36 ，对硅灰约为0 . 4 。 |
| 6. | The judge criterion of plastic shrinkage cracking for cement based material was studied through the testing of plastic tensile strength and plastic shrinkage capillary stress of cement mortar and concrete
摘要采用自行设计的塑性抗拉强度、塑性收缩开裂应力测定装置测试了水泥砂浆、混凝土塑性抗拉强度和塑性收缩开裂应力。 |
| 7. | The trends of plastic shrinkage cracking in concretes made with the same water or cement paste content per cubic meter are similar with the above case , but the critical w / c ratio is about 0 . 45 - 0 . 4 and 0 . 4 , respectively
2 ）在一定砂率范围内，较低和较高砂率对应的混凝土拌合物不易开裂，而中间某一临界砂率对应的混凝土拌合物开裂较大，这一临界砂率变化范围为36 - 43 % 。 |
| 8. | The material of cement - treated aggregate based on new strength standard has the enough strength and little shrinkage that is helpful to decrease shrinkage crack of cement - treated aggregate and reflective crack of asphalt layer
经试验验证，根据该标准所确定的水泥稳定碎石基层的级配组成、强度均符合要求，且收缩量小，致使其收缩裂缝减少，沥青面层的反射裂缝也相应减少。 |
| 9. | It provided the reference to improve the anti - cracking capability of high strength and high performance concrete from the point of view of constructional technology and curing requirement . the result shows that the more the binder material or sand rate , the more serious the shrinkage cracking
最后运用该软件分析在外界温湿度变化以及不同养护条件下，混凝土内部的温湿度变化规律及其由此引起的温度应力和湿度应力，为从施工养护方法上改善高强高性能混凝土抗裂性能提供参考。 |
| 10. | There was a borderline w / b ratio , above which concretes containing fly ash or silica fume were more sensitive to plastic shrinkage cracking than that of concretes without fly ash or silica fume , and below which fly ash or silica fume high performance concretes can restrain the plastic shrinkage cracking
6 ）在室内控制环境条件下，降低环境温度、风速以及提高相对湿度均可减少新拌混凝土水分蒸发速率，从而减少塑性收缩裂缝。相比之下，提高环境相对湿度对减少水分蒸发和裂缝更为明显。 |
