Properties and performance of high strength fibre reinforced concrete by using steel and polypropylene fibres
… concrete containing a combination of steel and polypropylene fibres under different exposure conditions. In this study, the physical and engineering properties of fibre reinforced concrete (FRC) are investigated by using steel fibre (SF) type hooked end and polypropylene fibre (PPF) type virgin …

Material properties related to fire spalling of concrete
… of selfcompacting concrete with the addition of polypropylene fibres (PP-fibres) during fire exposure are presented. A verification calculation, based on the measured values of temperature in the cross-section of the fire exposed concrete, was compared with results from a full-scale fire test …

Concrete at high temperatures: hygro-thermo-mechanical degradation of concrete
… are adopted. Additionally, the effect of polypropylene fibres as a spalling prevention technique is modelled via a modification of the intrinsic permeability formulation. The transport model is further coupled with a damage-based mechanical model for concrete. The fully coupled …

The fracture toughness of silica fume concrete using experimental and numerical techniques
… tests were conducted on concrete reinforced with polypropylene fibres. The post cracking performance of such concrete was assessed using a toughness index evaluated from the area under the load-displacement relationships.

Bond between reinforcing bars and concrete under impact loading
… under impact loading was studied for plain, polypropylene fibre reinforced, and steel fibre reinforced concretes. The experimental program included setting up an impact test system, in which an impact load with considerable energy could be generated, and in which the applied loads, …

Integración de materiales de cambio de fase en placas de yeso reforzadas con fibras de polipropileno aplicación a sistemas de refrigeración y calefacción pasivos para almacenamiento de calor latente en edificios
… the compound material (melamine formaldehyde and polypropylene fibres. The regulations in force -referred to the different gypsum derived products- have been revised to observe its compliance. Experimentally the aggregates have been combined varying the proportions to obtain different compound, …
