“…At the same time, numerous attempts are being made to partially replace clay with recycled waste materials in the production of bricks [ 5 ] (e.g., slag [ 11 ], pumice [ 12 ], waste marble [ 13 ], paper waste [ 14 ], waste glass [ 15 ]).…”

This paper primarily assesses the scale of adverse changes to the compressive strength of different types of silicates due to the influence of moisture. The study covers three groups of silicate units of different strength classes—15, 20 and 25—obtained from three different manufacturers. It was demonstrated that in all studied groups, moisture significantly decreased the compressive strength by about 30–40%. In addition, microstructural studies were conducted to analyze the relationship between the specific porosity structure of each group of silicate bricks and their compressive strength. On the basis of SEM (Scanning Electron Microscopy) and EDS (Electron Dispersive Spectroscopy) analysis, the elemental composition of individual silicates was determined and the contact zone between the aggregate and the binder was determined, which largely influenced the obtained compressive strength of each silicates. Next, the study referred to the utility of the normative procedure used to determine the strength class of samples with different geometries and at different moisture concentrations. The results of the calculations showed the high accuracy of the normative-based assessment of strength class, regardless of the manufacturer and the moisture values during examination.

“…The H3PO4-hardened molassesbonded brick is preferred when 2.5% of borax was not used (Benk and Coban, 2012). 39.6% pumice was found to be effective and increased the porosity of fired bricks while the density lowered to 1.58 g/cm 3 at 900°C and increased to 1.61 g/cm 3 at 1000 o C respectively (Gencel, 2015). Lime, gypsum and diatomite used to produce bricks showed a positive correlation between lime content and strength/density of the bricks.…”

In this research, kaolin, ball clay, sawdust and rice husk were used to produce insulation bricks through the solid state synthesis method. Two temperatures, 1100oC and 1200oC were used to sinter the green samples. X-ray fluorescence, scanning electron microscopy, compressive strength tests etc. were used to analyse the properties of the produced bricks. Chemical composition analysis on the starting raw materials showed that SiO2 and Al2O3 were the major constituents while Fe2O3, Na2O, K2O and TiO2 were the minor constituents. As the amounts of kaolin used in preparing the samples decrease, the bulk density, modulus of rupture and cold crushing strength of the bricks decreases while the water absorption capacity, linear shrinkage increases. The thermal analysis showed that on heating the samples, the reactions were mainly exothermic with between 8 to 10 mW/mg of heat released. The morphology of the samples showed that the pores began to collapse when the amount of kaolin present is below 70 wt. %. Sintering the samples at 1100oC and 1200oC led to slightly different values in the results and is therefore very significant. Keywords: Insulation bricks, Kaolin, sawdust, rice husk, temperature effects

“…(2007), zemin iyileştirmesinde bu ve bunun gibi doğal bir biçimde oluşan kaynakların değerlendirilmesine değinmişlerdir. Ayrıca, pomza katkılı fırınlanmış harman (kil) tuğlası üzerine yapılan bir çalışmada, pomza katkı kullanarak tuğlanın birim hacim ağırlığının düşürülmesi ile birlikte yapının ölü yük değerinin azaltılması hedeflenmiştir (Gencel, 2015). %10, %20, %30 ve %40 oranında pomza katkı kullanılarak imal edilen tuğlalar 900°C ve 1000°C'ta 2 saat boyunca fırınlanmıştır ve termal iletkenlik karakteristiği ve su emme kapasitesi incelenmiştir.…”

Gelişen ülkeler veya şehirlerde artan nüfus ve yapılaşma ile birlikte inşaat sektörünün temel yapı taşı durumunda olan agregaya ihtiyaç artmaktadır. Yapıların ihtiyacını karşılamak amacı ile yerleşim yerlerine yakın taş ocakları açılmakta ve ocaklardan elde edilen malzemeler her ne kadar inşaat sektöründe büyük oranda kullanılabilse de; arta kalan ince taneli malzeme atık olarak beklemektedir. Bu çalışmada, Aksaray ili çevresinde yer alan pomza taş ocağından atık olarak elde edilen ürünlerin, Avanos (Nevşehir) yöresi killeri ile çeşitli oranlarda karıştırılarak zemin özelliklerine olan etkisi araştırılmıştır. Kil numunesinin, ince taneli atık pomza malzemesi ile belirli oranlarda karışımından yapılan koni batma likit limit deneyi ve modifiye proktor deneyi sonucunda kil numunesi içerisindeki atık pomza miktarı arttıkça likit limit değeri ve maksimum kuru birim hacim ağırlığı azalmakta, optimum su içeriği artmaktadır.
