hardening of concrete meaning in English

混凝土硬化

On the course of hardening of concrete , the improvement of performance mainly lies in the decrease of plasticity cracks and interior cracks of concrete in quantity and in dimension and the enhancement of medium continuity
在混凝土硬化过程中纤维改善了混凝土的内部结构，主要表现在减少了混凝土的塑性裂纹和内部微裂纹的数量和尺寸，提高了混凝土材料介质的连续性，从而改善了混凝土的综合性能。
Through flat experiment and circle experiment , we research the causes of cracks before hardening of concrete and after . through ingredient experiment , we research the influence of shrinkage from some ingredient ( coal ash , crushed stones and fiber ) . in addition , we test some methods of construction to strengthen the anti - crack capacity of r . c . slab in building sites
通过平板试验和圆环试验，研究了混凝土在终凝前和终凝后裂缝的各种影响因素；通过掺合料试验，研究混凝土的一些掺合料(粉煤灰、碎石和纤维)对其收缩变形的影响；另外，还在施工工地进行一些增强楼板抗裂能力的构造措施试验。
