摘要:
为研究不同水灰比对钢筋混凝土梁裂缝的影响,以混凝土开裂荷载、时间,出现位置,分布、发展状况以及梁破坏时的极限荷载、时间为主要观测指标,制作三组9 根不同水灰比的钢筋混凝土梁试件,加静载使其产生裂缝发展直至破坏.实验结果表明:水灰比在0.550~0.600 范围内,随着水灰比的增加,裂缝出现时间变早,剪切裂缝强度下降,裂缝发展越来越快,最终梁极限荷载下降,强度降低,但对裂缝出现位置并无太大影响.
Abstract:
In order to study the influence of water-cement ratio on reinforced concrete beam, the cracking load and cracking time, the position of cracks, distribution and development condition, ultimate load and time of failure of the beam were defined as main observation indexes. Nine RC beams of different water-cement ratios that were divided into three groups were designed to carry static load until they lost load carrying capacity. The results show that as water-cement ratio differs from 0.550 to 0.600, with the increase of the water-cement ratio, cracking time is advanced, and cracking shearing strength drops, besides, cracks develop at a faster speed, ultimate shear strength descends, and yet the position of cracks is not affected.
