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。
Combined with a project C50 external walls were doped with non-doped thermal expansion material contrast test strength and limited expansion rate as an indicator of the mix design, the final temperature measurement results and the actual cracks confirmed that the cold shrinkage The application of dry-shrunk joint compensation mode in wall crack control also proves that the new type of temperature-controlled swelling material can solve the cracking effect of wall.
