Effect of Organic Compounds on the Special Properties and the Microstructure of Autoclaved Brick.

After a long decomposition process, organic matter turns into humic substances. In humus, carbon dioxide (CO) bound in photosynthesis is brought back to the soil, where it should be used by its ecosystem. This is important because similar relationships are found in modern concretes and concretes designed with the use of geochemical modeling (possibility of the C-S-H phase for storing harmful substances).

Influence of Waste Basalt Powder Addition on the Microstructure and Mechanical Properties of Autoclave Brick.

In the production of building materials, there has been an increased interest in the use of by-products and industrial waste in recent years. Such modifications make it possible to solve not only technical and economic problems, but also environmental problems. This article describes the use of basalt powder waste in sand-lime products (silicates).

Onboarding in Polish Enterprises in the Perspective of HR Specialists.

The article discusses onboarding in Polish enterprises analyzed from the perspective of HR specialists. The subject of consideration in the article falls within the area of broadly understood concern for the sustainable development and well-being of employees adjusting to a new work environment during their adaptation period. Actions taken by HR specialists have a significant impact on the behavior of employees and their well-being and satisfaction in the new workplace, including commitment and care for all stakeholders involved in building a positive psychological climate at the time of starting work.

Cement Bypass Dust as an Ecological Binder Substitute in Autoclaved Silica-Lime Products.

The cement industry is one of the most developed industries in the world. However, it consumes excessive amounts of natural resources and can negatively impact the environment through its by-products: carbon dioxide (CO2), cement clinker dust (CKD) and cement bypass dust (CBPD). The amount of dust generated in the cement clinker production process depends largely on the technology used.

Experiencing Stress among Different Professional Groups in the Context of Their Age.

The subject of this article is the identification of coping with stress and experiencing stress in three groups of the same number of people, different in terms of their occupation: professional soldiers of the Polish Army with the rank of an officer, people employed in managerial positions, and specialists working in independent positions in the context of their age. The analysis of the literature and the research carried out refer to the concept of sustainable development. This indicates the need to take care of limiting excessive stress and improving the mental well-being of all employees, regardless of the demographic characteristics and nature of the work performed.

Thermal Conductivity of Sand-Lime Products Modified with Foam Glass Granulate.

Waste glass constitutes a significant part of general waste worldwide. Unfortunately, only a small percentage is recycled. It is, therefore, quite important that it can be applied in the production of construction materials.

The Influence of Hydrated Lime and Cellulose Ether Admixture on Water Retention, Rheology and Application Properties of Cement Plastering Mortars.

In this article, the effect of hydrated lime and cellulose ether on the water retention, rheology, and application properties of plasters was studied. For mortars, the consistency, bulk density, and water retention were tested. Rheological measurements of pastes included yield stress and plastic viscosity.

Recycled Glass as a Substitute for Quartz Sand in Silicate Products.

In 2016, an average of 5.0 tons of waste per household was generated in the European Union (including waste glass). In the same year, 45.
