环氧树脂各组分对环氧树脂砂浆的性能影响研究
Influence of Epoxy Rein Components on Performance of Epoxy Resin Mortar
摘要
Abstract
In this work,orthogonal experimental approach was employed to investigate the effects of two bisphenol-A type epoxy resins(single and compound blending),two reactive diluents(single and compound blending),and five curing agents on the mechanical and bond properties of epoxy resin mortar.Results show that the effects of three factors on the flexural strength and compressive strength of epoxy resin mortar from large to small is curing agent,epoxy resin and diluent,and the influence of curing agent type is much greater than other two factors.All three factors exhibit comparable influence on the dry and wet bond strength of epoxy resin mortar.SEM and XRD analyses reveal the absence of Ca(OH)2 crystals in the epoxy resin mortar,indicating that the epoxy resin mortar system effectively inhibit cement hydration and growing stresses from Ca(OH)2 crystallization,thus enhancing both compressive strength and flexural strength of epoxy resin mortar.关键词
