“…There are other approaches to reducing emissions related to the fabrication of building construction materials, such as foamed concrete (FC) and lightweight concrete. FC can be produced with soil or slag powder and is suitable for the thermal insulation of walls or for backfill [15]. Recent studies have also shown that potentially problematic wastes, such as polystyrene and cement kiln dust, can be mixed to create lightweight cementitious bricks as an eco-friendly alternative to traditional cement bricks [16].…”

To meet energy-saving requirements, in recent years, Saudi Arabia’s construction industry has focused on researching the use of naturally available resources as raw materials. This study looks at the behavior of Viroc, specifically using pinewood and its compression properties in eco-friendly concrete. The study demonstrates the feasibility of adding pinewood to concrete and provides a theoretical basis for the promotion of dry pinewood particles and Portland cement composite materials. The Viroc specimens used in the study are 18 mm long, 12 mm wide, and 12 mm deep. The mechanical properties of the specimens were tested and compared by using a universal testing machine (UTM) and the Ansys software program 2022. The test results show that Viroc can increase the compression strength and modulus of the construction material as well as increase its brittleness and toughness (mechanical properties). The results show that it is feasible to incorporate wood and cement, resulting in a new type of Viroc composite material in an eco-friendly environment.

“…Instead of fly ash, other types of waste are used in foam concrete, for example, various types of slag. In the study [28], compositions of foam concrete with slag were developed. It has been established that with the introduction of slag from 25% to 55%, with increasing its dosage, the characteristics of the composite deteriorate.…”

Foam concrete is a popular energy-efficient construction material with a fairly wide range of usage in buildings and structures. Increasing ecological efficiency and reducing construction costs by the application of different types of industrial waste in the manufacturing technology of this composite is a promising direction. The main goal of this study is to investigate the possibility of coal dust (CD) waste inclusion in the technology of energy-efficient cellular concrete produced by foam concrete technology. Test samples of foam concrete were made using coal dust by partially replacing cement in the range of 0–10% in increments of 2%. The following primary characteristics of foam concrete were studied: fluidity of mixtures; compressive strength; density; thermal conductivity of foam concrete. An X-ray diffraction analysis of foam concrete composites was performed, which showed changes in their phase composition when using coal dust as a modifier. Coal dust in rational quantities from 2% to 6% improves the physical and mechanical characteristics of foam concrete and increases the structure uniformity. The optimal values of the foam concrete characteristics were recorded at a dosage of coal dust of 6%. At the same time, the density decreased by 2.3%, the compressive strength increased by 15.6%, and the thermal conductivity coefficient decreased by 8.9% compared to the ordinary composition. The use of the resulting foam concrete is advisable in enclosing structures to create high energy efficiency of buildings and structures due to the improved structure and properties.
