The aim of this research is to evaluate the minimum amount of YE in mortar that allows spores of&nbsp;<em>Bacillus sphaericus</em>&nbsp;to germinate with limited negative effect on mortar properties. Two YE concentrations of 2 and 5 g/l were tested and compared to a reference without YE. To protect the bacteria in the mortar matrix, spores or cells were encapsulated into porous expanded clay. The ureolytic activity of bacteria with YE variation, the mechanical properties and the healing ability of mortar were assessed. The results show that a YE concentration of 2 g/l provided acceptable mortar properties, while it was sufficient for spores to germinate and provide a satisfactory healing ability to resulting mortar. When vegetative cells are used as a healing agent, it is best to omit yeast extract from the mortar mixture.</p> P. Risdanareni, L. Ma, J. Wang, N.

Pervious concrete can be a successful safety solution for increasingly frequent heavy rains and floods. This study focuses on achieving an optimized pervious concrete within the scope of international standards by analyzing concretes made with different W/C ratios and vibration times. The results of the study show the strong influence of parameters such as porosity, permeability, and mechanical strengths. Concrete with 0.35 W/C ratio and 40 seconds vibration time was selected for its adequate physical and mechanical properties.</p> J. Ximenes, C. Jesus, J. Aguiar, J.

A total of 54 prescriptions were used in the studies, which investigated six different variables. Strength, density, and thermal conductivity analyses were performed. Values were in the range of 0.57-2.75 MPa for strength, 344-592 kg/m<sup>3</sup>&nbsp;for density, and 0.089-0.132 for thermal conductivity. Three variables were identified with each having the most significant effect on strength and density values. H<sub>2</sub>O<sub>2</sub>, curing temperature, and expanded perlite had the most effect on strength, while H<sub>2</sub>O<sub>2</sub>, curing temperature, and alkali concentration had the most significant effect on density. Most influential parameters are plotted on ternary graphs to ensure that the foam concrete (CLC) masonry units used in all types of masonry walls, whether load-bearing or not, can operate under the specified performance conditions.</p> C.

Detailed macro and microscopic analysis and determination of mechanical properties were performed on the collected cores. It was found that cracks in the coarse and fine aggregate resulted from advanced alkali-silica reaction. No impact of de-icing agents on the destruction of the concrete pavement was found, while attention was paid to the potential intensification of concrete degradation resulting from the increase in traffic on motorways. The results obtained are a detailed supplement to the German research, as this region (Rostock) has not been analysed before.</p> D. Jóźwiak-Niedźwiedzka, A.

One method of using mining waste is to use it as aggregate in road construction. However, this alone is not enough to dispose of the entire amount of waste generated. Another promising method of using mining waste is the production of building ceramics (bricks). However, some properties (e.g. the content of natural radionuclides) of the waste may limit the possibility of such use. In the scope of this work, the properties of bricks made from mining waste - shale collected from dumps, were examined. It has been shown that the properties of bricks prepared in this way meet the criteria set out in various standards and legal acts and can be used in construction.</p> M. Bonczyk, J.

This paper identifies the influence of filler typology and bitumen content on the mechanical response of asphalt mortars before and after water action. Two fillers were evaluated: Portland cement and Calcium carbonate, along with different contents of a penetration bitumen (B35/50). Stiffness, ductility, and fatigue were evaluated through a new protocol for asphalt mortar samples using a 3-point-bending test on DMA (Dynamic Mechanical Analyzer). The use of Portland cement presents higher stiffness, lower ductility, and improved fatigue and water resistance compared to Calcium carbonate. It is also possible to optimize bitumen content based on fatigue results. Content beyond the optimal reduce variations after water action but compromise fatigue resistance. Lower content leads to a poorer performance in both terms. This methodology enables asphalt mortar characterisation as a tool to optimise the design of asphalt materials.</p> R. Tauste, A.E.

However, limited research has assessed the behaviours of mixtures including both technologies. This study performed research aligned with environmental considerations and sustainability to examine the design and manufacturing of dense asphalt mixtures incorporating a crumb-rubber modifier through a wet or dry process and a specific vegetable additive for WMA technologies. The results indicated that, when rubber is added through a wet process, and a WMA vegetable additive is incorporated, the mixture can be manufactured and compacted at temperatures approximately 25 °C below that of the control mixture, while keeping the mechanical properties within the specifications.</p> A.M.
