There are numerous waste management methods besides simple landfilling, including reuse, open-loop or closed-loop recycling options. The described research explores the applicability of an open-loop recycling method, the processing of end-of-life textiles to produce fibres for fibre-reinforced geopolymers, to combine various waste streams for the production of an environmentally friendly binder system. By the examination of different textile waste processing methods, the most valuable fibrous material was produced with the application of a rotary shear and a vertical cutting mill, eliminating the necessity of manual cutting. As the most common base material of the textiles was found to be polyester and cotton, these were deemed useful for fibre reinforcement. The flexural strength showed a significant increase with the addition of 5 wt.% fibres, indicating the possibility of more than doubling the flexural strength of geopolymer specimens. Based on the microstructural analysis, however, even though there was good adhesion between the fibre and the geopolymer matrix, the latter showed inhomogeneities with higher fibre addition, indicating the need to further optimise the production steps, such as mixing time, vibration time, etc. LA - English DB - MTMT ER - TY - CHAP AU - Szalontai, Lajos AU - Mucsi, Gábor ED - Ágoston, Csaba TI - Megújuló és frissülő képzések a fenntarthatóság jegyében a Miskolci Egyetem Műszaki Föld- és Környezettudományi Karának palettáján T2 - Zöldgazdaság 2023/24 PB - Környezetvédelmi Szolgáltatók és Gyártók Szövetsége (KSZGYSZ) CY - Budapest SN - 9789638812575 PY - 2024 SP - 236 EP - 237 PG - 2 UR - https://m2.mtmt.hu/api/publication/34529294 ID - 34529294 LA - Hungarian DB - MTMT ER - TY - JOUR AU - Fóris, Ildikó AU - Mucsi, Gábor TI - Glass foam experiment with eggshell as foaming agent and red mud as additive material JF - ÉPÍTŐANYAG: JOURNAL OF SILICATE BASED AND COMPOSITE MATERIALS J2 - ÉPÍTŐANYAG-JSBCM VL - 75 PY - 2023 IS - 4 SP - 132 EP - 135 PG - 4 SN - 0013-970X DO - 10.14382/epitoanyag-jsbcm.2023.18 UR - https://m2.mtmt.hu/api/publication/34761653 ID - 34761653 LA - English DB - MTMT ER - TY - CHAP AU - Mucsi, Gábor ED - Veresné Somosi, Mariann ED - Sikos T, Tamás TI - Ipari hulladékok innovatív hasznosítási technológiái T2 - A fenntarthatóság holisztikus megközelítésben PB - Akadémiai Kiadó CY - Budapest SN - 9789634549314 PY - 2023 SP - 292 EP - 308 PG - 15 UR - https://m2.mtmt.hu/api/publication/34492392 ID - 34492392 LA - Hungarian DB - MTMT ER - TY - CHAP AU - Fóris, Ildikó AU - Zsuzsanna, Oláh AU - Mucsi, Gábor ED - Molnár, Dániel ED - Molnár , Dóra TI - Effects of eggshell and power plant fly ash preparation and dosing on the properties of insulating glass foam tablets using fractionated and unfractionated glass powder T2 - XXVI.

The influence of the amount of red mud and fly ash on the properties (foaming temperature, mechanical strength, specimen density and porosity, thermal conductivity) of the tablets was studied. The foamed tablets contained 2.5 wt % binder material, 0.1 wt % foaming agent, 5 wt % fly ash, and red mud as additives in different ratios (0 – 40 wt %). After homogenization, the ground raw materials were pressed into tablets at 30 MPa using a hydraulic piston press. The products were heat treated at different temperatures with different heating rates. The final product’s properties were measured (specimen density, thermal conductivity, and mechanical strength through falling and abrasion resistance tests). The most convenient results were shown at 5 wt % red mud in this case, the specimen density and thermal conductivity were the lowest, the values were 0.3 g/cm3 and 0.036 W/mK. If 5 wt % of fly ash was added to the mixture the density value stayed the same, the thermal conductivity increased to 0.048 W/mK, but the mechanical strength of the tablets rapidly increased.
