“…Hava kabarcıklarının etkisiyle parçalanan proteinler, peptit bağlarını meydana getirerek hidrofobik özellikteki küçük molekül yapılarını oluşturur. Bu işlem çözeltinin yüzey gerilimini azaltır ve hava kabarcıkları için arabirim oluşturur (Panesar, 2013). Protein yapısındaki köpük ajanları, yüzey gerilimini düşürmesi ve köpük içerisinde hava boşluğu yaratmasının yanı sıra moleküller arası hidrojen bağları yardımıyla stabil hava kabarcıklarının oluşumunu sağlar (Kuzielova ve ark., 2016 Tablo 1'de de görüleceği üzere en yaygın kullanıma sahip köpürtme ajanları; yumurta beyazı, yumurta albümini, jelatin, süt proteinleri olarak bilinen kazein, peynir altı suyu proteini ve soya proteinleridir.…”

Gıda sanayinde toz formda ürün eldesinde kullanılan kurutma yöntemlerinden biri de köpük kurutmadır. Bu yöntem diğer kurutma yöntemlerine kıyasla süre ve maliyet açısından daha iyi olup, meyve, süt ve deniz ürünleri gibi çeşitli gıdaların toz forma dönüştürülmesinde kullanılmaktadır. Köpük yapısının oluşumu köpürtme ajanları ve/veya stabilizörler ile sağlanmaktadır. Köpük yapısına dönüştürülen gıdanın yüzey alanı genişler ve kurutma işleminin etkinliği artar. Bu derlemede gıdanın köpük kurutma yöntemi ile toz forma dönüştürülmesi aşamasında uygulanan işlem parametreleri, elde edilen ürün özellikleri ve köpük kurutma yönteminin çeşitli gıda maddelerine uygulanabilirliği hakkında bilgi sunulmaktadır. Drying of Foods with Foam mat Drying Method A R T I C L E I N F O A B S T R A C T Review ArticleReceived 02 December 2016 Accepted 17 January 2017The foam mat drying is one of drying methods applied to produce powdered food in the food industry. Foam mat drying, which is better than other methods of drying in terms of drying time and cost, is used to convert powder form of various foods such as fruit, milk and seafood. The formation of the foam structure is provided with foaming agents and/or stabilizers. The surface area and drying efficiency of food product increase with conversion to foam structure. In this review, knowledge about the process conditions applied during the process of converting the food into powder form by foam drying method, the obtained product properties and the applicability of foam mat drying to various foods are presented.

“…Other oxides present in small amounts include Fe2O3, TiO2, CaO and MgO. Even though there are a number of researchers (Amran et al 2015;Panesar 2013;Jones and McCarthy 2005) considering the FC as their main field of work, however, they took a little interest in Metakaolin inclusion within their field of research. Hence, for this experimental work, water reducing admixture was used with some mixes contained MK, particularly at 50%, which is highly reactive with the cement and has a high demand for water absorption.…”

“…The content of the foaming agent has a considerable effect on the properties of fresh and hardened concrete. Therefore, the mechanical and physical properties of FC can vary depending on the type of foaming agent and dosage used in the mix (Panesar 2013). It has been reported that the excessive foam volume results in a drop in flow, decrease in density, and decrease in compressive and tensile strengths (Amran et al 2015).…”

“…OAMED concrete (FC) is a composite material, generally consists of ordinary Portland cement (OPC), fine aggregate (sand), foaming agent (which is an air entraining agent), admixtures and water, (Ramamurthy et al 2009;Panesar 2013). For the last two decades, it has been used as a filler for trenches and gap filling owing to its main characteristics of being selfflowing and self-compacting with good flawability.…”

“…While Synthetic foaming agents are amphiprotic substance that are strongly hydrophilic and easily dissolve in water yielding air bubbles. However, when introducing synthetic agents into concrete, which is a complex chemical environment, the compatibility of surfactant and cement particles is critical to effectively entrain the desired air content and concrete microstructure (Panesar 2013).…”

This paper investigates the mechanical properties at a fresh and hardened states of a new foamed concrete. The aim is to develop and produce a hydrophobic lightweight foamed concrete with enhanced properties for structural use. Foamed concrete generally is made of ordinary Portland cement (OPC), fine aggregates, foaming agent, admixtures and water. Metakaolin (MK) and water reducing admixture were used with the mix in this study. The physical properties of the mixes in their fresh state, mainly the consistency of the mixes was determined. All the mixes prepared were undergone rheology test at fixed water/cement (w/c) ratio of 50%, testing for flowability and spreadability. Compressive strength testing was carried out on 100 mm cubes and the results revealed that the compressive strength of foamed concrete decreases with a reduction in density. Flexural strength and flexural modulus, which were tested on 100 x 100 x 500 mm prisms, were also found to decrease with the reduction in density. The use of MK improved compressive strength as well as flexural strength development for normal and foamed concrete. Higher improvement was noted for the flexural strength with the use of a higher dosage of MK.

Researchers have continuously attempted to reduce and recycle construction waste. Ceramic waste is mainly a byproduct of the manufacturing process. About 25% of the waste is produced because of dimension defects or incurring problems throughout the industrial process. This article aims to highlight the alternative uses of ceramic waste. In this research, ceramic waste at a powder status is reduced to fine aggregates. Here, ceramic waste powder (CWP) is used in different ratios of 25%, 50%, 75%, and 100% replacing the fine aggregate weight. Aluminum powder is used to obtain aerated concrete (AC). Glass fibers are added in ratios of 1%, 1.5%, and 2% of cement weight to obtain a fiber‐reinforced AC. The unit weight, compressive strength, splitting tensile strength, and thermal conductivity are estimated. Furthermore, scanning electron microscopy is performed to investigate the microstructure features of the composite. The results exhibit better performance in compressive and splitting tensile strength when fine aggregates were replaced by 25% and 50% of CWP. In addition, 1.5% of GFs enhance the compressive and splitting tensile strength. In addition, increasing the CWP decreases the unit weight of fiber‐reinforced AC. It is shown that CWP strongly influences the thermal conductivity of the fiber‐reinforced AC, resulting in a high composite resistant to heat transmission. The technique for order preference by similarity to an ideal solution method is used to obtain the optimal mix.
