In total, 7 types of mortars were prepared: with water containing the micro-nano bubbles of O2, O3 or CO2 as 50% or 100% substitute of ordinary mixing water (tap water) and the reference mortar prepared using tap water. In order to determine the influence of water with micro-nano bubbles of gases, the consistency of fresh mortar and the physical properties of hardened mortar, i.e., specific and apparent density, total porosity, water absorption by weight and capillary absorption, were established. The mechanical strength of the considered mortars was studied as well by conducting the tests for flexural and compressive strengths following 14, 28 and 56 days. Reduced workability and capillary absorption were observed in the modified mortars within the range of 0.9-8.5%. The mortars indicated an increase in the flexural strength after 28 days ranging from 3.4% to 23.5% and improved compressive strength in 1.2-31%, in comparison to the reference mortar. The conducted studies indicated increased flexural and compressive strengths along with the share of micro-nano bubbles of gases in the mixing water.

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

http://www.mdpi.com/1996-1944/11/5/658 DOI: 10.3390/ma11050658 Streszczenie: This paper describes a method of designing and producing innovative mineral-asphalt mixtures, which utilize waste aggregate from the recycling of sanitary ceramics. The work presents the basic properties of the ceramic material, the investigation concerning the microstructure of the aggregate obtained from the grinding of waste, and a comparison with the images obtained for the aggregates usually employed in mineral-asphalt mixtures. The mixtures were designed for the application in the wearing course. Four series of mixtures were prepared. In the first and second, the ceramic aggregate constituted a partial substitute for dolomite, whereas in the third, we substituted granodiorite, and the fourth series contained only dolomite. The mixtures were examined for the content of soluble binder, the bulk density of samples, the presence of voids, the space filled with binder, and the susceptibility to water and frost corrosion. The obtained results were compared with the standard requirements. The microstructure as well as the contact zone in the considered mineral-asphalt mixtures are presented based on research conducted by means of a scanning electron microscope (SEM).

https://www.mdpi.com/2073-4360/10/4/420 DOI: 10.3390/polym10040420 Streszczenie: The influence of roughness and the way it affects the adhesion properties and surface free energy (SFE) of polysiloxanes hydrophobised basalt fibres-reinforced cement mortars were determined in this article. The physical properties of mortars were investigated in the experimental part, which also explored the impact of hydrophobisation and basalt fibres (BF) addition on SFE, frost resistance, contact angle (CA), and roughness. A device capable of calculating all parameters was used to indicate the surface roughness and 3D topography. Prior to and after conducting surface and weight hydrophobisation, the contact angle of mortars was specified. Subsequently, it was used for carrying out SFE calculation by means of Neumann's method, enabling us to characterize the adhesion properties and wettability of mortars. The research indicated that the surface roughness was substantially decreased, in turn raising the frost resistance. The corrosion resistance drops when the surface roughness, water absorption, and number of fibres in the mortar increase. The SEM images presenting the structure of polysiloxane coating and mortars were provided. Projekt/grant: : działalność statutowa WNET PSW, 2017- WNET/KNT/ZB/1

DOI: 10.1063/1.5051104 Streszczenie: The aim of the presented research was to determine the impact of roughness characterizing nanopolymer-hydrophobised mortars modified with basalt fibres on their wettability. The experimental part pertains to the physical properties of mortars modified with basalt fibres as well as the influence of basalt fibres and hydrophobisation on the roughness, contact angle, surface free energy and frost resistance. Indication of surface roughness and 3D topography was carried out in a device enabling calculation of all parameters. The contact angle of mortars (?w) was determined before and after hydrophobisation by means of a single measurement liquid. It constituted the basis for SFE calculation with Neumann's method, characterizing the wettability and adhesion properties of mortars. The studies enabled to determine the hydrophobisation efficiency of mortars with basalt fibres. The obtained results confirmed the possibility of producing the mortars reinforced with basalt fibres and characterized by appropriate protection of surface against moisture and frost, which depends on, i.a. surface roughness.

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
