Behaviour of composites based on blended matrix with CNT during extreme temperatures

摘要

The paper presents the results of research focused on modification of silicate matrix by secondary energy products with current reinforcement using carbon nanotubes (CNT). A suitable CNT sorting method was assessed first. In the following, the influence of various composition of the blended binder (substitution of cement in quantities 15, 25 and 35 %) of reinforced CNT to basic parameters and micro structure was examined. Amphibolite was used as a filling agent. Temperature exposition took its course up to 1,200 ℃ with consecutive controlled cooling.
