摘　　要：通过试验研究了低温条件下环氧砂浆抗压和粘结性能。结果表明:低温环境对试件养护前期的抗压与粘结强度影响较大,强度提高缓慢。结合工程实际提出了优化的环氧砂浆施工工艺,以保证工程的质量。Through an experimental study made on the compressive strength and bonding performance of epoxy mortar under low temperature condition, the result shows that the low temperature environment has a larger impact on the compressive strength and bonding performance of the sample during its early curing period, i.e. the strength is to be slowly enhanced. Therefore, an opti- mized construction technology for the epoxy mortar is put forward herein in combination with the actual engineering practice con- cemed.
