20.500.12556/RUL-151781 The influence of animal glue as an additive on the properties of lime architectural grouts Vpliv dodatka živalskega lepila na lastnosti arhitekturnih injekcijskih mešanic Organic additives from plant and animal extracts were commonly used in lime mortar in the past to improve and modify its properties. In modern times, they have been replaced by inorganic additives. The objective of this research is to investigate the influence of fish animal glue and the role of the filler particle size distribution on the fresh and hardened properties and durability of lime grouts. Wet density, water retention, fluidity, and injectability were tested in the fresh state. It was found that the particle size distribution of the selected filler, which can increase the packing density of the solid particles of the grout, and the W/B ratio have a great influence on water retention and fluidity. In the hardened state, porosity and compressive and splitting tensile strength were evaluated on 90-day- and 365-day-old specimens. The presence of animal glue improved the mechanical properties, due to a higher carbonation rate. The combination of the two fillers that resulted in a better packing of filler particles decreased the splitting tensile strength of the grout. To investigate the durability of the selected grouts, adhesion strength was measured on discsandwich models after non-accelerated and accelerated aging. The results show that the adhesive strength of grouts aged under laboratory conditions is lower than that of grouts subjected to accelerated aging. civil engineering architectural injection grout dry hydrated lime organic additive animal glue mechanical properties durability gradbeništvo arhitekturna injekcijska mešanica hidrirano apno organski dodatek živalsko lepilo mehanske lastnosti obstojnost true false true Angleški jezik Slovenski jezik Članek v reviji 2023-10-20 08:06:19 2023-10-20 08:06:24 2023-10-21 03:45:43 0000-00-00 00:00:00 2023 0 0 17 str. iss. 17, art. 12903 Vol. 15 2023 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 691 2071-1050 10.3390/su151712903 162434051 sustainability-15-12903-v2.pdf sustainability-15-12903-v2.pdf 1 4D7D5A3ABF23B1C7CF6B9D25FA3363CF cf82c96c4079bcdbff3e97a27655e0339e99ded94355fe71340b427045375c52 532e1dd2-6f0f-11ee-b452-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=176843 https://www.mdpi.com/2071-1050/15/17/12903 Prost dostop 1 ccd7ca41-6f0e-11ee-b452-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=176842 Fakulteta za gradbeništvo in geodezijo 0 0 0
