Within the scope of this study, the foam solution was prepared by properly mixing sulfonate based foam agent with water. Furthermore, this solution was mixed with the mixture of fine sand, cement, and water to produce foamed concrete. The mixture ratios which are the percentage of foam solution used in foam concrete were chosen as 0, 20, 40 and 60% by vol. After these groups reached 28 days of strength, they were heated to 20, 100, 400 and 700 degrees C respectively. Afterward, high-temperature effects on the foamed concrete were obtained by employing physical and mechanical properties tests. Additionally, SEM (scanning electron microscope) and EDX (energy-dispersive X-ray spectroscopy) tests were employed to analyze the microstructure, and mu-CT (micro computed tomography) images were used to reconstruct 3-D models of the heat-treated specimens. Then, these models are analyzed to examine the void structures and the changes in these structures due to the high temperatures. The study has shown that the void structures reduce the high-temperature effects and the foam solution could be mixed with concrete up to 40 % by vol. where the high strength of foamed concrete is non-mandatory.

The impact of alkali pretreatment and post-pretreatment conditioning on the surface properties of rice straw affecting cellulose accessibility to cellulases KARUNA, Nardrapee; ZHANG, LU; WALTON, Jeffrey H.; Couturier, Marie; Öztop, Halil Mecit; Master, Emma R.; MCCARTHY, Michael J.; JEOH, Tina (Elsevier BV, 2014-09-01) Rice straw was pretreated with sodium hydroxide and subsequently conditioned to reduce the pH to 5-6 by either: (1) extensive water washing or (2) acidification with hydrochloric acid then water washing. Alkali pretreatment improved the enzymatic digestibility of rice straw by increasing the cellulose accessibility to cellulases. However, acidification after pretreatment reversed the gains in cellulose accessibility to cellulases and enzymatic digestibility due to precipitation of solubilized compounds. Sur...
The effect of aromatic diboronic acid on characteristics of polybenzoxazine based on phenol and 4-aminomethylbenzoate İPEK, HALİL; Hacaloğlu, Jale (2018-11-23) In this study, a polybenzoxazine, (PPab) based on phenol and 4-aminomethyl benzoate and its composites containing various amounts of 1,4-benzene diboronic acid, (BDBA) were synthesized by stepwise curing. It has been determined that both thermal stability and char yield were increased as the amount of BDBA incorporated was increased. The improvements in thermal characteristics were associated with condensation reactions of B-OH of BDBA and not only with hydroxyl groups of polybenzoxazine but also ester grou...
The early heat of hydration of blended cements incorporating GGBFS and ground basaltic pumice (GBP) BİNİCİ, HANİFİ; ÇAĞATAY, İSMAİL HAKKI; Tokyay, Mustafa; KÖSE, MEHMET METİN (2006-11-01) In this study, the effect of blended cements containing additives on the heat of hydration and the rate of heat liberation was investigated. The blended cements were prepared by using clinker, ground granulated blast-furnace slag (GGBFS) and ground basaltic pumice (GBP). Two groups of specimens were prepared by the grinding method of intergrinding and separate grinding. For each group of specimen, two Blaine values of 2800 +/- 30 cm(2)/g and 4800 +/- 30 cm(2)/g and four different ratios of additives, which ...
The effect of 3-hydroxyphenylboronic acid on thermal characteristics of polybenzoxazine based on phenol and 4-aminomethylbenzoate Ipek, Halil; Hacaloğlu, Jale (2020-07-01) In this study, a polybenzoxazine, (PPab) based on phenol and 4-aminomethyl benzoate and its composites containing various amounts of 3-hydroxyphenylboronic acid, (HB) were prepared by stepwise curing. It has been found that thermal properties of composites were improved as the amount of HB introduced was increased. The improvements in thermal characteristics were associated with condensation reactions of hydroxyl groups of polybenzoxazine and ester groups on the aniline linkages yielding a highly cross-link...
The effects of some methacrylate monomers used as liquid component on tensile and flexural strengths of a poly (methyl methacrylate) denture base resin Do'an, Orhan Murat; Bolayir, Giray; Keskin, Selda; Boztug, Ali; Do'an, Arife; Bek, Buelent (2006-12-01) This study was conducted to observe the effect of different monomers on tensile and flexural strengths of poly (methyl methacrylate) (PMMA) denture base resin when they were used as a liquid component. A conventional heat-cured denture base polymer powder was mixed with ethyl, isobutyl and tert-butyl methacrylate monomers, respectively. After the polymerization process was completed, the tensile and flexural strength values of these specimens were compared with those that of PMMA resin specimens polymerized...
