چکیده
The macroscopic aspects of adding basalt fiber (BF) to concrete has been the subject studies that document great increases in compression strength. Research into microscopic reinforcement mechanism is still an exploratory stage, and quantitative analysis visual observation fibers matrix are difficult. In this paper, effect on studied by means computed tomography (CT) scanning technology digital image processing (DIP) technology, combined with macro-mechanical properties obtained from unconfined strength test, micro point view. At same time, visualization realized help Avizo. results show increase dosage, peak stress first then decreases. When dosage 3 kg/m3, 44.4 MPa, which 41.85% higher than ordinary concrete. Additionally, proportion macropores least, best dosage. It found when angular distribution φ relatively uniform, uniform forms a dense network structure, significantly However, too high, it will lead accumulation produce macropores, these excess mainly appear horizontal direction do not contribute

متن کاملAccelerated Heat Aging Study of Phenolic/Basalt Fiber Reinforced Composites
One of the greatest impediments to use polymer-matrix composites is their susceptibility to degradation when exposed to the elevated temperatures and the limited knowledge on the thermal and mechanical properties of these composites at such temperatures. The objective of this study is to evaluate the effects of accelerated heat aging on the tensile properties of the Woven Basalt/Phenolic (WBP) ...
متن کاملFibre reinforced autoclaved aerated concrete studied by computed tomography
The production process of fibre reinforced autoclaved aerated concrete results in a preferential orientation of the fibres. The fibre orientation largely influences the strength and the deformation behaviour of this building material, therefore information on the fibre orientation is highly desirable. Computed tomography measurements allow for the non destructive investigation of the material. ...
متن کاملCreep Behavior of Basalt and Glass Fiber Reinforced Epoxy Composites
The creep behavior of basalt fiber reinforced epoxy (BFRE) and glass fiber reinforced epoxy (GFRE) composites was studied through tensile testing at high temperature. To study the effect of reinforcing epoxy, the micro glass powder (MGP) was added at various volume percentage into the epoxy resin in BFRE composites. The initial strain for all the specimens were evaluated and compared with each ...
