“…Wśród nich wymienić można na przykład mielony odpad perlitu ekspandowanego (10)(11)(12)(13)(14)(15)(16)(17), popioły ze spalania łusek i słomy ryżowej (18)(19)(20)(21), mieloną gezę wapienną (22)(23), pył marmurowy (24) czy popioły ze spalarni odpadów komunalnych (25)(26)(27)(28). Dużo uwagi poświęca się również alkalicznie aktywowanym spoiwom złożonym z odpadowych lub syntetycznych dodatków mineralnych i szkieł (29)(30)(31)(32)(33)(34)(35)(36)(37).…”

“…They are including e.g. ground waste expanded perlite (10)(11)(12)(13)(14)(15)(16)(17), rice husk and straw ashes (18)(19)(20)(21), ground limestone (22)(23), marble dust (24) or municipal waste incinerator bottom ashes (25)(26)(27)(28). A great deal of attention is also paid to alkali--activated binders, based on waste or synthetic mineral additives and glasses (29)(30)(31)(32)(33)(34)(35)(36)(37).…”

“…Especially in the case of some of the ashes, due to signifi cant differences in chemical composition, depending on the source and batch of the material (25). In comparison with these additives, waste glass cullet is characterized by exceptionally good properties.…”

“…The material is available globally in large quantities -clear glass z relatywnie niewielkiej produkcji lub wyłącznie lokalnego występowania. Również, szczególnie w przypadku niektórych popiołów, ze względu na znaczne różnice w składzie chemicznym w zależności od źródła i partii materiału (25). Na tym tle wyjątkowo korzystnie prezentuje się odpadowa stłuczka szklana.…”

In the study, a field trial was carried out to evaluate the applicability of ground waste glass cullet as a binder component, in the industrial production of precast concrete elements. The influence of glass cullet addition on the properties of fresh and hardened concretes was compared to siliceous fly ash. Moreover, the effects of a partial substitution of the natural aggregate with recycled concrete and expanded clay aggregate were determined. The compressive strength of concretes, in which 25% of cement was substituted with ground waste glass cullet, was even 20% higher compared to elements with an analogous addition of siliceous fly ash. Over 56 days, no drops in strength related to the harmful effects of the alkali-silica reaction were observed. Replacing half of the natural aggregate with graded recycled concrete aggregate, allowed to lower the thermal conductivity of the walls by approx. 10%, with no negative impact on the compressive strength of precast elements. However, a decrease in the consistency of fresh mix was observed after 30 minutes. Replacing the 2÷8 mm gravel with the same fraction of expanded clay resulted in an approx. 18% decrease in thermal conductivity, while maintaining satisfactory mechanical properties. It was concluded that ground waste glass cullet can be successfully used as a fly ash replacement in the production of precast concrete elements.

“…Wielu badaczy wykorzystuje reakcję pucolanową do wyjaśnienia braku występowania szkodliwej reakcji wodorotlenków sodu i potasu z reaktywną krzemionką (29)(30)(31). Reakcja pucolanowa z udziałem mielonego szkła [SM] była przedmiotem wielu badań (1,7,14,(32)(33)(34)(35)(36). Wynika z nich, że dodatek szkła, wprowadzanego jako substytut cementu, może wynosić 10% (37), 20% (38) lub nawet 60% (39).…”

Effect of temperature on the long-term properties of mortars containing waste glass powder and ground granulated blast furnace slag

2021

View full text Add to dashboard Cite

The paper presents new and unique results of two-year examinations of mortars containing ground glass, as a substitute for 15 or 30% by mass of ordinary Portland cement in comparison with the properties of mortars with the analogous addition of ground granulated blast furnace slag, in different temperatures. Moreover, after a two-year curing period, the mortars were autoclaved. Samples were subjected to compressive strength measurements, XRD analysis and the determination of calcium hydroxide content, by means of thermogravimetric analysis. The results confirm that as an additive, glass powder, thanks to its pozzolanic properties, can compete with common SCMs like granulated blast furnace slag. Additionally, a reduction in strength was not observed after the autoclaving process, for the mortars with 15% glass addition. The data collected in the paper confirms that the pozzolanic properties of ground glass allows its use as an additive. It also shows the ability of these mortars to maintain a constant level of strength in the long term and even after the autoclaving of two-year-old samples
