Abstract

In this experimental study the effect of alkali silica reaction [ASR] on the mechanical properties of concrete namely compressive strength, fl exural strength, splitting tensile strength, modulus of elasticity and pull-out strength is presented. The effect of the specimens’ geometry on ASR expansion has also been studied. The results confirm that ASR expansion of over 0.04% causes significant losses in the mechanical properties of concrete, albeit at differing rates. Moreover, this study proves that the specimen geometry has an important role on ASR expansion rate.

ASR膨胀对混凝土力学性能的影响

试验研究了碱硅反应对混凝土抗压强度、抗折强度、劈裂抗拉强度、弹性模量和抗拔强度等力学性能的影响。研究了试样几何形状对ASR膨胀的影响。结果证实，ASR膨胀超过0.04%会导致混凝土力学性能的显著损失，尽管损失幅度不同。此外，本研究还证明了试样几何形状对ASR膨胀率有重要影响。
