碱骨料分布广泛地区材料供应方案研究

Material supply research in areas rich of alkali aggregate

碱骨料反应将导致混凝土失去设计性能,直接影响混凝土的设计,甚至直接影响工程的质量和造价。此文通过实际案例研究,提出在碱骨料分布广泛地区就地取材、混合搭配砂石料的材料供应方案,此方案既能保证工程质量又能控制工程造价。

Alkali aggregate reaction will cause concrete losing its designed performance, thus selection of alkali aggregate could affect concrete design of a project, or even its quality and cost. Based on actual case study, this article proposes a scheme of local material mixed with sand - gravel aggregate in areas rich of alkali aggregate, which can not only ensure engineering quality but also control engineering cost.
