When added to MAMs as an aggregate, ceramic building material, which has different properties than the raw material (clay), may significantly influence the aggregate properties, including the wettability, porosity, asphalt adhesion, and consequently the mixture durability. The material's microstructure was found using SEM. The wetting properties of mineral-asphalt mixtures were determined by measuring the contact angles (CA) of their surfaces, using water as the measuring liquid. The total surface free energy (SFE) values were determined using the Neumann method. When analyzing the research results, it can be noticed that the chemical composition of the ceramic aggregate has a significant influence on the adhesion of asphalt to its surface due to the chemical affinity. Waste ceramic aggregate, despite its acidic pH value being connected with its elevated silica content, exhibits good adhesive properties.

DOI: 10.1016/j.conbuildmat.2019.06.145 Streszczenie: The study on the physical properties and durability of concrete with admixture cellulose nanofibrils (ACNF) and cellulose nanocrystals (CCNC) was presented in the paper. The following characteristics of the concrete were defined: absorptivity, density, apparent density, open porosity, contact angle (CA), surface free energy (SFE), compressive strength, flexural tensile strength, freezing-thawing resistance. The use of ACNF and CCNC results in different wetting and adhesion properties of concrete. The highest CCNC addition yielded a concrete with the lowest CA with water and the highest SFE values that evidenced the increased adhesion properties and wettability. The microstructure of concrete with ACNF and CCNC and distribution of cracks and pores within them were investigated by scanning electron microscope (SEM). CCNC improves the freezing-thawing resistance. Projekt/grant: : działalność statutowa WNET PSW, 2018-WNET/KNT/ZB/1

Tytuł pracy: Wettability and Surface Free Energy of Granodiorite, Dolomite and Recycled Ceramic Aggregate Tytuł całości: W: Central European Symposium on Thermophysics 2019 (CEST), Banska Bystrica, Slovakia, 16-18 October 2019 / ed.

DOI: 10.1063/1.5120133 Streszczenie: The study of wetting properties and surface free energy (SFE) of granodiorite, dolomite and recycled ceramic aggregate was presented in the paper. Every tested aggregate had different wetting properties. Based on the SEM study, the microstructure was shown. Wetting properties of various aggregates were determined by measuring the contact angle of their surface using water as measuring liquid. Many factors influence the contact angle, including physical and chemical homogeneity, roughness and surface contamination, type of measuring liquid, drop size of measuring liquid, humidity, ambient temperature, etc. Measurements were carried out 0 minutes after the time of application of the drops. The total SFE was determined using the Neumann method. Analyzing examination results it can be noticed that the values of contact angles depends on the absorbability of aggregate and smoothness of its surface. The results of contact angle measurements proved that all contact angles for ceramic aggregate were lower than contact angles for dolomite and granodiorite. That causes the total SFE for ceramic aggregate was higher than SFE for dolomite and granodiorite aggregate. The highest contact angle was noticed for granodiorite. The smallest contact angle with water was obtained by ceramic aggregate. This is due to physical characteristics of this aggregate. Ceramic aggregate is characteristic of the high absorbability. This indicates an increased wettability and increased adhesion properties.

The composition of the two mineral-asphalt mixtures was prepared: the mixtures with dolomite and the mixtures with dolomite and recycled ceramic aggregate. The use of different aggregates results in diversification of the wetting properties in porous bituminous mixtures. The microstructure was shown based on the SEM study. The wetting properties of mineral-asphalt mixtures were determined by measuring the contact angle of their surface using water as measuring liquid. Measurements were carried out immediately after the time of application of the drops. The total surface free energy (SFE) was determined using the Neumann method. While analysing the examination results it can be noticed that the values of contact angles depends on the type of aggregate used in mixtures and the smoothness of mineral-asphalt mixtures surface. The highest contact angle was noticed for the bituminous mixture with dolomite aggregate on flat surface. The smallest contact angle with water was obtained for the mineral-asphalt mixture with dolomite and recycled ceramic aggregate on rough surface. This is due to the physical characteristics of this aggregate. Ceramic aggregate is characterized by the high absorbability. This indicates an increased wettability and adhesion properties.
