dc.description.abstractFreezing and thawing resistance is very important characteristic also in the case of lightweight concrete. The paper deals with the influence of periodic freeze-thaw cycles on lightweight concrete fracture parameters values. Sets of lightweight concrete specimens (prismatic shape) are cyclically frozen in range from +20C to -20C. The main aim of the experimental part is to determine and compare the mechanical/fracture parameter values of a composite both frozen and non-frozen. The non-frozen specimens are air/water-cured. A three-point bending test of beams with a central edge notch is used in order to determine the fracture parameters values. It particularly covers effective fracture toughness and fracture energy. The notch is cut after 200 freezing cycles before fracture tests. The other parameters values - compressive and splitting tensile strength on the specimen fragments - are determined.en
