Objectives: To evaluate the strength and durability behaviour of concrete specimens that have been reinforced with micro reinforcements made polypropylene fibers microfillers nanofillers such as alccofine nanosilica, respectively. Methods: The samples were to achieve a targeted 33 MPa. In this experiment, added mix in volume fractions 0%, 1%, 0.2%, 0.3%, 0.4%, optimum percentages (15%) nanosili...

PURPOSE To evaluate the effects of copaiba oil on the correction of abdominal defect treated with the use of polypropylene/polyglecaprone mesh in rats. METHODS A defect in the abdominal wall was created and corrected with polypropylene/polyglecaprone mesh in 36 rats. They were randomly distributed into three groups: control, copaiba by oral administration (gavage) and copaiba oil dip in the m...

One of the main risks in low-densified sandy soils with presence water and an external force such as earthquake is generation liquefaction. The influence several types reinforcement on liquefaction resistance, polypropylene fibers, geofibers, cement fibers shown this study. Cyclic stress-controlled triaxial tests cyclic strain-controlled were performed saturated samples without reinforcements u...

Concrete is most widely used construction material in the world. Fiber reinforced concrete (FRC) is a concrete in which small and discontinuous fibers are dispersed uniformly. The fibers used in FRC may be of different materials like steel, G.I., carbon, glass, aramid, asbestos, polypropylene, jute etc. The addition of these fibers into concrete mass can dramatically increase the compressive st...
