塑性收缩裂缝 meaning in Chinese
plastic shrinkage cracks
Examples
- Effects of water - cement ratio on plastic shrinkage cracking of concrete
水灰比对混凝土塑性收缩裂缝的影响 - The thesis studies the influence of compounding polypropylene fiber and expansion agent to plastic shrinkage of mortar
摘要混凝土的塑性收缩裂缝，是其结构原生缺陷的主要来源，无论是否可见，都会影响混凝土的耐久性。 - 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。 - In the paper the effects of the made parameters , the main materials and environmental conditions on plastic shrinkage cracking were investigated . it can be concluded as following : 1 ) there was a critical w / c ratio of maximum plastic shrinkage cracking between lower and higher w / c ratio of concrete mixtures made with the same cement content per cubic meter , concretes with lower or higher w / c ratio being less prone to plastic shrinkage cracking and the w / c critical ratio critical of maximum plastic shrinkage cracking being about 0 . 5
本文研究了配制参数、主要原材料以及环境条件对新拌混凝土塑性收缩裂缝的影响，结果表明： 1 ）单方混凝土水泥用量一定时，较低水灰比和较高水灰比对应的混凝土拌合物不易开裂，而中间某一临界水灰比对应的混凝土拌合物开裂较严重，这一临界水灰比为0 . 5 ；单方混凝土水用量或水泥浆量一定时，混凝土拌合物的塑性开裂趋势与上述情况相似，但临界水灰比分别为0 . 45 - 0 . 4和0 . 4 。 - The proportion of plastic shrinkage cracking is rather high in early cracking . the plastic shrinkage cracking would effect construction appearance and promote the propagation of drying shrinkage cracking or other types cracking , but also provide a passage for aggressive agents penetrating and moving to the concrete mass
塑性收缩裂缝在早期裂缝中占有相当大的比重，其存在不仅影响工程外观，促使干燥收缩裂缝或其它形式裂缝的发展，而且还将为侵蚀性介质向混凝土基体渗透、迁移提供通道，对混凝土的耐久性造成严重影响。
