The Research of Qualitative Characteristics of Construction Materials based on Concrete Waste

Various construction waste is generated in large quantities and can be used in different ways. The authors examined several construction sites, defined the range of construction waste and their proportion in overall total. For this research concrete waste in construction sites have been investigated. The paper presents a methodology of carrying out experiments on determining physical characteristics of concrete waste and items produced from concrete waste and the results of the tests measuring their resistibility and water absorption. The obtained data shows conditions and criteria of waste sorting and justifies the most effective way of re-using concrete waste.
