摘要
文章结合某一工程C50外墙进行了掺与不掺抑温膨胀材料的对比试验,以强度和限制膨胀率为指标进行了配合比设计.最终的测温结果与实际裂缝观察结果证实了冷缩干缩联合补偿模式在墙体裂缝控制中的应用意义.也证明新型抑温膨胀材料解决墙体开裂的良好效果。
In combination with the external walls of a project using the C50 concrete,comparative tests mixed and non-doped thermal—suppression material were did.limit expansion rate and strength were designed as an indicator,the final result and the actual temperature crack observation confirmed the application significance in the wall cracks control of 'joint shrink shrinkage compensation mode',also demonstrated good effects of new suppress temperature expansive materia]in wall crack-control.
