RECYCLING IN CONSTRUCTION MATERIALS - ANALYSIS OF THE USE OF AMORPHOUS MATERIALS POLY(ACRYLONITRILE-CO-BUTADIENECO-STYRENE) (ABS) IN STRUCTURAL CONCRETE.

Activities related to industrial aspects in the 21st century focus on, among others, low-emission economy, sustainable construction, recycling of processed materials, possibilities of recovery of building materials after the decision to demolish and ecology. The most popular building material is currently concrete used to make monolithic structures and prefabricated elements. There are many modifications to concrete, and the topic of recycling in building materials has become a priority. One of the materials is ABS, i.e. poly(acrylonitrile-co-butadiene-co-styrene). ABS is an amorphous, metastable material characterized by high resistance, impact strength, hardness and scratch resistance. It is also resistant to light and UV radiation and has favorable insulating properties. The only drawback is the lack of resistance to acids, esters and ketones. In order to determine the impact of ABS modification on the properties of the concrete mix, the following tests were performed: compressive strength, density and microscopic tests.
