摘要
混凝土抗拉强度远低于抗压强度,当混凝土内部产生拉应力超过其抗拉强度时,就会产生裂缝。通过现场施工过程中的观察和查阅有关混凝土应力方面的书籍,对混凝土裂缝限制标准、混凝土裂缝产生的原因及预防裂缝的措施等进行阐述。
The tensile strength of concrete is far below compressive strength,when the tensile stress of concrete internally generated exceeds its tensile strength,cracks will occur. Through on-site observation during construction and access to the concrete stress-related books,the standard limit of concrete cracks,concrete cracks courses and prevention measures are described in detail.
