Research on Fractal Characteristics of Cement-Based Materials by Nitrogen Adsorption Method TANG Minga,LI Jingqib School of Material Science and Engineering, Shenyang Jianzhu University, Shenyang, Liaoning, 110168, China atm24690309@126.com, blijingqi2469@126.com Keywords: cement-based materials; pore; fractal; nitrogen adsorption Abstract：In order to confirm the surface fractal dimension of the internal pore of complex porous materials by means of the FHH model and nitrogen adsorption method.
The complexity ,the particularity in macroscopic and microscopic structure ,the universality of use parts of the constituent materials, which determine the concrete materials science had to depend on the latest research results of various disciplines of cross to improve their own.
Concrete materials fractal theory can be used to be a new branch of materials scientific researching, as following the materials science, micromechanics, fracture mechanics, cement chemistry, rheological etc.
Pore structure characteristics is a important issue about cement-based materials science study.
From now on, in the cement concrete materials science study, pore characteristics and pore structure theory research become a focus.
