“…While studying clay plasters with cork, Maaloufa Y. et al [ 40 ] noticed that the thermal conductivity decreased from 0.51 for clay alone to 0.246 W∙m −1 ∙K −1 for the composites with 100% cork and that their density decreased as well. The Moreira’s [ 4 ] experimental results pertaining to the mechanical and hygrothermal characterization showed that replacing sand with expanded cork in the mixtures lowers their hardened density, compressive strength, and thermal conductivity.…”

The aim of the research that is presented in this paper was to evaluate the physical and mechanical properties of heat-insulating mortars with expanded cork aggregates and different binders. In this work, the measurements of surface roughness and adhesion strength, supported by determination of basic mechanical and physical parameters, such as density, bulk density, open porosity, total porosity, absorbability, thermal conductivity coefficient, compressive strength, flexural strength, and frost resistance of mortars containing expanded oak cork, were performed. The scanning electron microscope (SEM) investigations demonstrated the microstructure, contact zone, and distribution of pores in the heat-insulating mortars containing expanded cork. The results indicated that the addition of expanded cork and different binders in heat-insulating mortars triggers changes in their roughness and adhesion strength. The SEM research confirmed the very good adhesion of the paste to the cork aggregate.

“…Table 6 presents the results of the durability and physical properties of mortars. Numerous studies confirming the influence of expanded perlite on the physical properties of cement composites are known in the literature [63][64][65][66] Analyzing the results, it can be unequivocally stated that the replacement of natural aggregate with expanded perlite reduces the density of mortars, which decreases as the number of perlite increases. This is due to the low specific gravity of perlite and high porosity of aggregate, which contributes to increasing the porosity of ready-mixed mortars.…”

The paper explores the possibility of covering the mortar with the lightweight aggregate by the nanopolymer silane and siloxane as surface hydrophobisation. The investigation involved the mortars with two types of hydrophobic agents diluted with water in a ratio of 1:4 and 1:8. Mortar wetting properties were determined by measuring the absorbability, water vapor diffusion, contact angle (CA) and surface free energy (SFE) of their structure. Surface micro-roughness and 2D topography were evaluated. Scanning electron microscopy (SEM) has shown the microstructure and distribution of pores in mortars. The reduction in absorbency after the first day of testing by 87% was shown. An improvement in frost resistance after 25 cycles by 97% and an 18-fold decrease in weight loss after the sulphate crystallization test were observed. The hydrophobic coating reduces the SFE of mortars and increases the CA. In the case of using silanes, a 9-fold increase CA was observed.

“…Mantar tanelerinden yapılmış malzemeler de darbe sesi yalıtımı, hava ile yayılan sesin yalıtımı ve ses yutumu için iyi akustik özelliklere sahiptirler [76]. Bu malzemelerin ısı iletim katsayısı 0,037 ila 0,050 W/m.K arasında, yoğunluğu 110 ila 170 kg/m 3 arasında, özgül ısısı ise 1,5 ila 1,7 kJ/kgK arasındadir [77,78]. Bu malzemeler paneller, şeritler halinde üretilebilirler.…”
