ABSTRACT The use of synthetic fibers as reinforcement for concrete replacing the steel reinforcement has been diffused worldwide in several applications, gaining prominence in the application for industrial floors, tunnel linings, road pavements, etc., i.e., continuous structures in contact with soil that require performance in the elastic medium. The present study investigated the applicability of concrete reinforced with synthetic fibers in the bottom slab of silos supported directly on the ground, being composed of an experimental study and a case study. The experimental study consisted of the analysis of the mechanical behavior of this concrete by testing three concentrations of synthetic fibers (3.0, 4.5 and 6.0 kg m-3) in a conventional simple... |

ABSTRACT The objective was to evaluate the influence of coffee husks as floor covering on the aspects of animal welfare such as behavioral characteristics, body surface temperature, and salivary cortisol levels of stabled boars. Sixteen boars were housed in individual stalls; eight were maintained in a conventional system with a concrete floor and eight were maintained on a concrete floor lined with coffee husks. The experimental period was 60 days. All animals were filmed two days prior to the start of the experiment, on both the 7th and 60th days after exposure to coffee husks, and finally two days after the removal of the material. During this period, the number of times that the animals ate, drank, stood, sat, lay down, and dug was recorded.... |
