چکیده مقاله:
The most important problem in dispersive soils is the problem of internal washing water
and the problems caused by it, which is especially relevant in hydraulic structures. It can
be seen that it was built on these soils. The recognition of the phenomenon of dispersive
and the identification of dispersive soils has caused more and more precise criteria to be
considered in the selection of loan sources for fine-grained soils. If it is necessary to use
dispersive soils, you must think of a solution to deal with the phenomenon of washing,
Many studies have been done on soil stabilization methods with lime and gypsum, but no
comprehensive research has been done on the effect of micro-silica on mechanical
parameters. The use of micro silica, as a by-product and waste of ferrous-silica factories,
can be considered as a cost-effective material, therefore, it can be effective in stabilizing
the soil from various aspects, which is discussed in this article. The addition of micro silica
with percentages (۲.۵, ۵, ۷.۵, ۱۰, ۱۲.۵, ۱۵ and ۲۰) of the resistance of different clay samples
was investigated and evaluated. The results indicated a significant increase in compressive
strength and bearing capacity, so that the addition of ۷.۵% micro silica increased the
compressive strength by ۷۰%.
