Experimental Study of Thermal Conductivity of Carbon Fiber Reinforced Cement-based Composites Yadong Biana and Ran Haib School of Civil Engineering and Architecture, Zhongyuan University of Technology, Zhengzhou 450007, China amobcoco@sina.com, blilyhai_2001@163.com Keywords: Carbon fiber; Cement-based composites; Thermal conductivity Abstract.
The heat engineering calculation is directly related to the material thermophysical properties while the heating efficiency of carbon fiber reinforced cement-based composites is evaluated.
The research on thermal conductivity of carbon fiber reinforced cement-based composites is an essential link which can provide the reliable evidence for the heat engineering calculation of the material.
And the purpose of the research is to obtain the specific corresponding relationship between the carbon fiber weight and thermal conductivity and provide the evidence for heat engineering calculation. 2 Experimental study 2.1 Specimen design The specimen of carbon fiber reinforced cement-based composites is made up of 425R ordinary Portland cement, ISO standard sand, high-strength PAN-based short carbon fiber (the average length is 5mm), carboxymethyl cellulose dispersant agent, silica micro powder(SiO2 weight is more than 95% and particle size is between 0.01 and 0.1µm), tributyl phosphate defoaming agent, FDN-1 high efficiency water reducing agent and some other raw material.

Selvadurai1, a 1Department of Civil Engineering and Applied Mechanics, McGill University, 817 Sherbrooke Street West, Montreal, QC, Canada H3A 0C3 apatrick.selvadurai@mcgill.ca Keywords: Dilatant fractures, interface mechanics, interface degradation, mathematical contact mechanics Abstract.
The performance of fractures is crucial to engineering activities associated with geologic disposal of hazardous wastes and greenhouse gases and hydraulic fracturing designed to extract oil and gas and geothermal energy resources.
The hydro-mechanical performance of fractures and geological interfaces are therefore of major importance to engineering geosciences.
