The purpose of this paper is an investigation of the possible role of zeolite and powdered Bayburt stones on the fresh and hardened properties of hydrated lime (CL90) mortars. Parameters studied in this paper form the main barriers to the use of hydrated lime in construction practice. Enhancement of these parameters is vital for mortar/substrate optimisation in masonry construction. The major concern of this paper therefore is the combination of wet mortar and brick substrate and most significantly the interaction between them at fresh and hardened states. The results show that transfer sorptivity and time to dewater hydrated lime mortars can be manipulated when zeolite and powdered Bayburt stones are used as replacement materials to the binder. Long setting time of CL90 mortars is decreased with the increasing replacement levels of both zeolite and powdered Bayburt stones. Experimental results also showed that the increasing replacement levels of zeolite and powdered Bayburt stones resulted in a dramatic increase in compressive strength and these results are also supported with the microstructural images. The ability to enhance water transport kinetics and mechanical properties of hydrated lime mortars with zeolite and powdered Bayburt stones should not be underestimated as this enables such materials to be used in construction practice more competently. These results have important practical consequences, not only in the initial adhesion of the mortar to the substrate but also in the strength of the set material and therefore the use of hydrated lime mortars may be encouraged if zeolite and Bayburt stones can improve the fresh and hardened state properties of these mortars.

The effect of red phosphorus on the fire properties of intumescent pine wood flour - LDPE composites Altun, Yasemin; DOĞAN, Mehmet; Bayramlı, Erdal (Wiley, 2016-08-01) Red phosphorus (RP) was used to improve the fire performance of wood flour - low density polyethylene (LDPE) composites containing ammonium polyphosphate (APP). The fire performance of LDPE-based composites was investigated by using limiting oxygen index (LOI), UL-94 standard, thermogravimetric analysis, and cone calorimeter. The addition of 30 wt% APP increased the LOI value from 17.5 to 24.2 and still burned to clamp (BC) in UL-94 test. The RP showed beneficial effect when combinedly used with APP. The ma...
Investigation of the effect of hydrated lime on low temperature cracking of asphalt concrete Varlı Bingöl, Başa; Güler, Murat.; Department of Civil Engineering (2019) The main objective of this study is to investigate the effect of hydrated lime on low-temperature cracking resistance of hot mix asphalt (HMA) mixtures. To this end, a comprehensive laboratory experimental program is established to evaluate the influence of hydrated lime modification, aggregate type, aggregate gradation and asphalt binder aging on temperature-related failure of HMA specimens. These specimens prepared from materials obtained from Turkish General Directorate of Highways are fabricated followi...
The Effect of Hydrolysis on the Antioxidant Activity of Olive Mill Waste Attard, Karen; Öztop, Halil Mecit; Lia, Frederick (2022-12-01) This study presents the effect of hydrolysis on the antioxidant activity of olive mill waste. The olive pomace samples were collected at different stages of maturity and were investigated for their phenolic content and antioxidant activity. Three different extraction procedures were employed, including methanolic maceration extraction and two hydrolysed procedures using 6 M HCL for acid hydrolysis and 10 M NaOH for alkaline hydrolysis. The total phenolic, flavonoid and ortho-diphenolic content, metal ion re...
Evaluation of a sand bentonite mixture as a shaft/borehole sealing material Akgün, Haluk (2018-11-01) The mechanical and hydrological characteristics of compacted sand bentonite mixtures with bentonite contents ranging from 5 to 40% were investigated in the laboratory in order to assess their use as a waste isolation material and to select an optimum sand bentonite mixture. Laboratory tests included compaction, compaction permeability, unconfined compression and direct shear tests which led to a recommendation to select a mixture with a bentonite content of 30% for the isolation of underground geological wa...
The effect of lime addition on the combustion properties and sulfur contents of three different coals Ozbas, Kazim Esber; Hiçyilmaz, Cahit; Kök, Mustafa Verşan (2002-01-01) In this research, combustion characterization of 3 different coals of Turkey, from the Soma, Tuncbilek, and Afsin Elbistan regions, were investigated with thermal analysis techniques such as differential scanning calorimetry (DSC) and thermogravimetry (TG/DTG). Lime was added to these coals in concentrations of 3, 7, and 10% by weight to investigate the change in combustible sulfur content and sulfur in ash. It was observed that lime has a positive effect on sulfur emission. Kinetic analysis was also perfor...
