avoidance of cracking meaning in Chinese
防止裂缝
Examples
- Some conclusions are drawn : the compressive strength and flexural strength of cubic specimens of steel fibre reinforced concrete increase with the dosage of steel fibre ; without change of dosage of steel fibre , the elastic modulus of steel fibre reinforced concrete increases with the concrete age ; steel fibre reinforced concrete is of obvious function in cracking resistance , but there is no obvious function in avoidance of cracking ; for both common concrete and steel fibre reinforced concrete , the variation of the internal temperature is different from that of the external temperature before the initial set of concrete , and the internal strain of both two kinds of concrete is great , and , in general , the variation of strain of common concrete is much greater than that of the steel fibre reinforced concrete ; after the initial set of concrete , the variation of the internal temperature of both two kinds of concrete is similar to that of the external temperature , and the variation of the internal strain is relatively small
结果表明:钢纤维混凝土立方体的杭压强度、抗弯强度随着钢纤维掺量的增加而增大;在钢纤维掺量不变的情况下,钢纤维混凝土的抗压弹性模量会随着龄期的增加而提高;钢纤维对混凝土的阻裂作用很明显,而对混凝土起裂的限制作用不明显;在混凝土初凝之前,无论是普通混凝土还是钢纤维混凝土,内部温度的变化规律与外界温度的变化规律不同,并且此阶段混凝土内部应变的变幅很大,普通混凝土应变的变幅要比钢纤维混凝土应变的变幅大得多;在混凝土初凝之后,无论是普通混凝土还是钢纤维混凝土,内部温度的变化规律与外界温度的变化规律相同,并且此阶段混凝土内部应变的变幅很小。
