The corrosive behavior of steel reinforcements causes issues in the concrete industry. To overcome this issue, alternative noncorrosive such as polymer fibers could be used. However, environmental protection becomes more important, sustainability must also considered solution. An to polymers based on raw oil is bio-based polymers. This study investigates suitability produced from polybutylene succinate together with cellulose and wood fillers reinforcements. Different mixtures succinate,...
Abstract The bond between polymer fibers and the surrounding cementitious matrix is essential for development of concrete reinforcement. single fiber pull‐out test (SFPT) standard characterization technique testing strength. However, different phases debonding cannot be distinguished by SFPT. This study investigates from with a modified SFPT proposes methods to change setup generate more valuable information on mechanism. was equipped linear variable differential transformers (LVDT), digital...
Abstract A crucial problem in concrete engineering is the corrosion of steel reinforcements. Polymer fibers as alternative reinforcement material can prevent corrosion; however, high adhesion to and good fiber mechanics are necessary for polymers be considered an reinforcement. This study tested different thermoplastic polymer materials evaluate their level concrete. The properties self‐drawn were analyzed by extracting from using single pull‐out test (SFPT). To determine mechanism,...
A reinforcement of concrete structures is needed because the low tensile strength concrete. Corrosion usually used steel reinforcments cause issues during time. Therfore, alternative reinforcements produced from non-corosive materials - like polymer fibers become more interesting. fiber has to reach high mechanical properties and a good bonding ability Both can be influenced by selection production process. Two polymers, polypropylene aliphatic polyketone are tested within this study. First...
A new approach for the friction and wear characterisation of polymer fibres under dry, mixed, hydrodynamic sliding conditions is developed. The production process tested described an introduction in fibre-reinforced concrete given. Tribotesting done on optimised tribometer capable measuring behaviour with diameters a few 100 µm lubricated conditions. Three extruded polypropylene macro varying are characterised tribological found industrial mixing process. It shown that detailed data can be gathered.
Based on the conventional pin-on-disc test method, a tribology rig was adapted and optimized regarding its ability to characterize polymer fibers. The method is explained first applications in field of tribological characterization single fibers are presented. sequence investigate (diameters only few 100 µm) generated such way that data can be recorded continuously as function time wear range from 10 µm several even during minutes. mode starts by applying line load dynamically progresses...
