Micro filler is important component of High Performance Concrete (HPC). It improves mix workability and provides dense microstructural packing of cement matrix. Pozzolanic micro-fillers, which consists of very fine amorphous non-cristalline silicate or alumosilicate particles, are the most effective concrete admixture. In many countries natural pozzolanic admixtures are not available, but commercial products (such as silica fume and metakaolin) are quite expansive. The paper discusses possibilities for using fine-sized glass particles, obtained from fluorescent lamp utilization as component for High Performance Concrete In the frame of experimental part recycled glass was activated by additionally ground in laboratory ball mill. Experimental data proved good pozzolanic activity of glass filler. The most effective solution is composite micro-filler containing silica fume and glass powder. Experimental work provides for testing compressive strength, durability factors and microstructure of hardened material. Elaborated cement compositions are characterized by high compressive strength (above 100 MPa), high water impermeability and low porosity. The results of research help to select the most effective way to utilize glass waste, with regards of economical and ecological aspects.
