项目摘要
Shrinkage characteristics of high shrinkage concrete which induced unprecedented cracking in a real concrete structure, shrinkage effects on air permeability of reinforced concrete prism shear strength of reinforced concrete beam under sustained tensile load and so on were investigated, which were made with the high shrinkage concrete. Results showed that the drying shrinkage of concrete depended on the drying shrinkage and Young' s modulus of aggregates, the air permeability of concrete increases with the increase of drying shrinkage, the shear strength of reinforced concrete beams is decreased by the shrinkage developed before loading when the reinforcement ratio is nearly 1. 0%.
研究了高收缩混凝土在实际混凝土结构中引起前所未有的开裂的收缩特性、收缩对钢筋混凝土棱柱体透气性的影响、持续拉伸荷载作用下钢筋混凝土梁抗剪强度的影响等。结果表明:混凝土的干燥收缩取决于骨料的干燥收缩和杨氏模量,混凝土的透气性随着干燥收缩的增加而增加,钢筋混凝土梁的抗剪强度因加载前产生的收缩而降低。加固率接近1. 0%。
