In addition, the mineral composition, physical and mechanical properties of aggregates from natural raw materials such as dolomite, granodiorite and waste ceramic aggregate (introduced as a partial substitute for the main aggregate) were analyzed. The shape of grains was examined by determining the shape and flatness index of aggregates, resistance to grinding and frost resistance. The tested properties have a direct impact on the durability of road surfaces. To this end, the adhesion of asphalt to the surface of the aggregates used was additionally determined. Determination of surface roughness and two-dimensional (2D) topography of tested aggregates was carried out. The aggregates microstructure examination, coupled with the energy-dispersive X-ray spectroscopy (EDS) analysis, was conducted to determine the morphology and texture of the aggregates as well as to identify the basic chemical components.

The experimental investigation consisted of tests carried out on cubes and prismatic samples made of SCLC and fibres-reinforced SCLC with variable content ranging from 0.5 to 1% of basalt fibres (BF) and/or 0.5% of steel fibres (SF). In this study, two variable contents of fine perlite aggregate were used: 5% and 15%. The workability (the slump-flow and t500 values) in fresh state SCLCs have been done. Extensive data on compressive and flexural tensile strength in bending behaviour, frost resistance and the microstructure including interfacial transition zone (ITZ) were recorded and analysed. The hybrid fibres-reinforced SCLC with perlite aggregate showed a more ductile behaviour compared to that of SCLC without fibres. Fibres bridge cracks during flexural tensile strength test. BF successfully protected porous SCLC against frost attack, whereas SF succumbed to damage. Projekt/grant: : działalność statutowa WNET PSW, 2017-WNET/KNT/ZB/1
