Adhesion and interaction of inorganic binder systems with a biodegradable polymer based on polylactic acid

Popis výsledku v původním jazyce

The interaction of common building materials with materials with diametrically different physical-mechanical properties represents one of the main problems in the creation of new types of composites. Some types of polymers have proven themselves in the past in the form of dispersed reinforcement. However, the overuse of plastics and the problem of their disposal now provides an open door for other alternative ideas. This work deals with the observation of the adhesion of a biodegradable polylactic acid-based polymer with composites such as conventional concrete, high-performance concrete and alkali-activated system under three-point bending test. Results show that adhesion and mechanical performance depend strongly on both the matrix and reinforcement type. Ordinary Portland cement concrete (OPCC) specimens demonstrated the best bond with polylactic acid (PLA) and the highest flexural strength gains, particularly with ribbed PLA (60 %). In contrast, high-performance concrete (HPC) and alkali-activated material (AAM) showed reduced adhesion, with flexural strength decreasing by up to 20 %.
