Abstract: In order to solve the problem of large error of analysis parameters in the existing research methods of micro compression characteristics of materials, a new research method of micro compression characteristics of nano carbon fibre reinforced concrete is proposed in this paper. Firstly, relevant instruments and materials are selected to prepare nano carbon fibre reinforced concrete. The water adsorption capacity, flexural strength, splitting tensile strength and toughness of concrete surface are calculated, and the characterisation of nano carbon fibre reinforced concrete is analysed. Finally, the micro compression strain distribution characteristics of nano carbon fibre reinforced concrete are determined, and the micro compression characteristics are studied. The experimental results show that this method can effectively analyse the micro compression characteristics of nano carbon fibre reinforced concrete, and the maximum error of characteristic analysis is no more than 10%.
Keywords: concrete materials; micro compression characteristics; Lambert Beer's law; water adsorption capacity; Kachanov model.
