concrete age meaning in Chinese
混凝土龄期
Examples
- The result shows that , when expansion agent is added , shrinkage can he compensated at some extent and crack can be restrained or reduced effectie1y and then the concrete ageing resistance can he enhanced , and under experiment condition , the appropriate mix content of the expansion agent should be less than 6 % , finally , for compensation shrinkage concrete , the restrictive expansion rete should he the primary index
结果表明,加入膨胀剂能补偿部分收缩,有效抑制或减少裂缝的产生,提高混凝土的耐久性;试验条件下试验所用膨胀剂的适宜掺量应小于6 % ;对补偿收缩混凝土,其限制膨胀率应作为第一性指标。 - 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。 - According to the concrete ages of different grout compartments , the concrete temperature rising process and the arching temperatures etc . , aiming at the optimization of technology and economy , the paper studies systematically the feasibility of applying different temperature control measures in different seasons and at different elevations ; and obtains characteristic parameters of arch dam temperature fields and stress fields so as to provide a basis for construction units to implement second stage cooling or third stage cooling according to particular demand at that time
为了达到技术上与经济上双优的目的,根据不同灌浆区的混凝土龄欺、混凝土温升过程、封拱温度等,系统研究了在不同季节里、在不同高程上采取不同温控措施的可行性,得到了拱坝温度场与应力场的特征参数,为施工单位根据当时的特定需要,进行二期冷却或三期冷却提供了依据。
