Abstract
In this paper, the formulations suitable for the simple sliding isolation technology of masonry structure of rural
buildings were experimentally studied. Three kinds of cement mortar with the strength grade M2.5, M5 and M7.5 mixed with talc
or graphite powder were designed as sliding isolation layers. Talc or graphite powder was mixed with an increase of 2.5%, a total
of 7 kinds of mix proportions, 39 kinds of conditions. Compression test, pressure- shear test and friction coefficient test based on
39 conditions was done respectively. The experimental results show that the modified mortar with talc or graphite powder can
meet the vertical pressure requirement of low- rise houses in villages and towns. The content of talc or graphite powder has a
significant effect on the shear strength of slip layer. With the increase of the content of talc or graphite powder, the friction
coefficient of the slip layer is generally reduced and the sliding performance of the slip layer is improved. The results of the
study can provide the basis for the formulation selection of the sliding isolation layer of rural buildings in different seismic
fortification intensity areas.
