The Nanocement Production

By mixing the cement and nanocement, the maximum dry density decreased about 13 and the optimum moisture content increased up to 18 compared to the normal soil. as a result of the stabilization with cement and nanocement, the increase in the uniaxial compressive strength of more than 12 times was observed compared to the unstabilized sample.
