ない。In general, in order to sufficiently exert the strength of the epoxy cement-based composite material, the condensation reaction of the epoxy resin and the hydration reaction of the cement in water are simultaneously advanced or the hydration reaction of the cement is somewhat increased. By precedently, it is necessary to form a composite hardened structure in which both components are finely intricate. However, the hydration of Portland cement tends to be significantly delayed in the presence of epoxy resin, and the condensation of the epoxy resin usually precedes to form a macro-discontinuous independent phase, which results in a coarse hardened structure and reduced strength. Easy to cause. On the other hand, the reason why the composite material of the present invention achieves high strength is not clear, but Li dissociated from the lithium compound
Ions act catalytically to the hydration reaction of ternary cement (the formation of ettringite and the hydration of C 3 S and C 2 S) in the coexistence of an epoxy resin, and this progresses rapidly and surely. It is presumed that it is possible to synchronize with the condensation reaction of. In this case, when Portland cement is used alone instead of the three-component cement, the action and effect of the lithium compound can hardly be expected.
