“…It is worth to notice that the research were conducted for the geopolymer mortar without any aggregate, because of that the achieved values for compressive strength are relatively low in comparison with other reported in literature [11][12][13][14][15][16][17][18][19].

This article analyses the influence of a short basalt fibre admixture on the mechanical properties of geopolymers, especially compressive strength. This preliminary research is the first step towards the development of a composite for fire resistant applications in civil engineering. This study investigates the behaviour of a fly ash based geopolymer containing basalt fibres. Fly ash from the coal power plant ‘Skawina’ (located in: Skawina, Lesser Poland, Poland) was used as the raw material. The chemical composition of this fly ash is typical for class F. Three series of fly ash based geopolymers were cast. In the first, short basalt fibres were added as 1% by weight of fly ash, in the second short basalt fibres were added as 2% by weight of fly ash and the third functioned as a control series without any fibres. Each series of samples were tested on compressive strength after 28, 14 and 7 days, and specimen density was determined. Additionally, microstructural analysis was carried out after 28 days. The results show that the addition of basalt fibres can improve the mechanical properties of geopolymer composites. Keywords: geopolymer, basalt fibre, composites, fire resistance

In developed and developing countries, the need for industrial and residential buildings is constantly increasing. The old buildings are either demolished or replaced by new buildings in order to maintain environmental awareness and due to limited usage areas. In this construction process, traditional Portland cement is used and also a serious solid waste problem arises due to the demolished buildings. Because of using Portland cement, a significant amount of greenhouse gas production is generated, as well as high levels of environmental pollution due to the accumulation of concrete solid wastes. New laws have been enacted in many countries to reduce greenhouse gas emissions due to Portland cement and for solid waste management, and even the establishment of recycling facilities for waste concrete has been encouraged. The reduction of greenhouse gas emissions and recycling of construction wastes have gained great importance both because of the protection of the natural environment and its contribution to the economy.In this study, more environmentally friendly geopolymer additives were used instead of traditional Portland cement for the recycling of construction waste, as well as geopolymer mortars were produced with different types of aggregates. The 0.4% basalt fiber additive series of the obtained samples were similarly produced. The geopolymer samples produced by using different aggregate types including the waste concrete aggregate were compared in terms of 28 days compressive strengths, ultrasound velocities, unit weight, voids ratio and water absorption results.

A tremendous amount of the nonbiodegradable microplastic waste has been generated after the outbreak of COVID‐19 by the widespread use of single‐use personal protective equipment, especially disposable medical masks (DMMs). This has caused harm to the health and safety of human beings and various organisms. Finding a way to properly deal with these single‐use medical wastes has become an urgent problem. In this paper, an innovative way was explored to use DMMs in geopolymer (GP). The physical properties, mechanical strength, and resistance to high temperatures (200–800°C) of the composites were investigated. The findings of the study revealed that DMMs had negligible influence on resistance to high temperatures, but showed a positive influence on enhancing the compressive and flexural strengths of GPs at ambient temperature. The optimum DMMs content was 0.4 wt%, at which the compressive and flexural strengths of the GP composites were enhanced by 5.8% and 22.68% compared with the pure GP, respectively. The same polypropylene (PP) fiber amount increased compressive and flexural strengths by 7.49% and 9.76%, respectively. This thus confirmed that DMMs can be sustainably utilized in green building materials, playing a role as PP fibers toughening and contributing to the effective management of waste plastics.
