高层建筑高强度混凝土构件裂缝问题与控制分析

Analysis and Control of Cracks in High-strength Concrete Components of High-rise Buildings

高强度混凝土掺加一定数量的外加剂与矿物原料,其水胶比较小,在实际施工中具有强密实、高体积稳定、高耐久、强抗压能力等特性,因此得到了广泛应用。由于高强度混凝土与普通混凝土在材质、性能上存在较大差异,所以其质量要求与施工标准也随之提高。鉴于此,文中主要探讨了高层建筑高强度混凝土构件裂缝产生的原因,并根据前人经验与实践总结了高强度混凝土构件裂缝的鉴定与控制措施,对于改善高层建筑高强度混凝土性能具有积极意义。

High strength concrete mixed with a certain amount of admixtures and mineral raw materials, its water gel ratio is small, and it has the characteristics of strong compactness, high volume stability, high durability, strong compressive capacity and so on in actual construction,so it is widely promoted. Due to the great differences in material and performance between high-strength concrete and ordinary concrete,its quality requirements and construction standards are also improved. In view of this, this paper mainly discusses the causes of cracks in high-strength concrete components of high-rise buildings, and summarizes the identification and control measures of cracks in highstrength concrete components according to previous experience and practice, which is of positive significance for improving and promoting the performance of high-strength concrete in high-rise buildings.
