- Abstract
Using unconventional raw materials for manufacturing different building products is an urgent task at present, in the light of the rapidly developing building production in Europe. The main subject of this study is usage of dolomite waste as alternative filler in production of concrete, due to the insufficient capacity of the dredged quartz sand production used in manufacturing concrete. The goal of the study is to examine mechanical and physical properties of the products containing different amount of dolomite waste and their comparison with properties of the traditional concrete. Mineralogical and chemical structure of dolomite sand has been investigated in details. It is determined, that compositions with dolomite sand require more water to provide the same mix consistency. Physical and mechanical properties, such as density, water absorption, strength, have been determined and compared. Tests have been also performed to determine frost resistance. Concluded, that alternative dolomite by-product sand can be successfully used as the quartz sand equivalent material.
