Mechanical fracture parameters of cement based mortars with wste glass powder
Original language description
Glass is an amorphous solid substance with pozzolanic properties that can be used as a partial substitute for ordinary Portland cement (PC) in cement based composites. In the research conducted for this paper, the PC was partially replaced by fine-ground waste laboratory borosilicate glass (in mixtures where 5, 10, 15 and 20 % by mass was substituted). Beam specimens with the dimensions 40 x 40 x 160 mm were prepared from each mixture. After demoulding, the specimens were kept under standard laboratory conditions. Basic tests were conducted at the age of 7, 28, 56, and 90 days: the compressive (fc) and flexural (ff) strengths were determined according to the ČSN EN 1015-11 standard. Specimens were also subjected to fracture testing at the age of 28 days. Three-point bending tests were conducted on beams with an initial central edge notch. Load vs. displacement diagrams were recorded and modulus of elasticity (E), fracture toughness (KIce) and fracture energy (GF*) were determined. Strength increased w
