Abstract
Industrial activity in the 21st century increasingly emphasizes a low-emission economy, sustainable construction, material recycling, and the closed-loop use of building materials. Concrete, in both cast-in-place and precast structures, remains the most widely used construction material. Numerous approaches to concrete modification have been developed, and the recycling of construction materials became a priority in the late 20th century, particularly in Western Europe and the United States, as well as in the context of the Earth Summits initiated in the 1990s. One such modifier derived from recycled plastics is acrylonitrile-butadiene-styrene (ABS). ABS is an amorphous, metastable polymer characterized by high strength, impact resistance, hardness, scratch resistance, favorable insulating properties, and resistance to light and UV radiation. Its main limitation is its low resistance to acids, esters, and ketones. To evaluate the effect of ABS modified with basalt powder on the properties of autoclaved aerated concrete (AAC), compressive strength was adopted as the primary performance indicator, and a functional usability profile was developed.
