Abstract:

In order to improve the mechanical properties of rock with lots of cracks, this study adopts electronic methods (X-ray diffraction and scanning electron microscopy) to determine the mineral compositions and micro structural characteristics of epoxy-repaired rock. Fractured rocks with low strength or high permeability may not be appropriate for dam foundation. The strength and durability of fractured rock are increased after chemical grouting. Test results show that, some of the cracks and voids are repaired by epoxy particles, resulted in the decreasing rock porosity. The proportion of epoxy resins is about 3.5%-5.5%, showing a discrete distribution and can not connect with each other.
