Atık depolama alanlarına gönderilen bu tür uçucu küller toprağa ve yeraltı sularına zarar vermektedir. Kangal Termik Güç Tesisi uçucu külü de beton sektöründe kullanılmamakta ve atık depolama alanına gönderilmektedir. Bu çalışmada, Kangal Termik Güç Tesisi uçucu külü, atık cam tozu ve kireç kullanılarak, kendiliğinden yerleşen yüksek dayanımlı briket üretilmiştir. Ağırlıkça %66 uçucu kül, %7 kireç ve %27 atık cam tozuyla üretilen briketin 56 günlük basınç dayanımı 67,5 MPa olmuştur. Üretilen briketlerin birim ağırlık, su emme, kılcal su emme ve ısıl iletkenlik değerlerinin yanında mikro yapıları da incelenmiştir. Üretilen briketler ulusal ve uluslararası standartlarda verilen sınır değerlerini sağlamıştır. Üretilen bu briketler kırsal kesimde yaşayan düşük gelirli insanların konut sorunun çözümüne yardımcı olabilir.

Some of the physical and mechanical properties of paving blocks having various levels of fine glass (FG) and coarse glass (CG) replacements with fine aggregate (FA) are investigated. The test results show that the replacement of FG by FA at level of 20% by weight has a significant effect on the compressive strength, flexural strength, splitting tensile strength and abrasion resistance of the paving blocks as compared with the control sample because of puzzolanic nature of FG. The compressive strength, flexural strength, splitting tensile strength and abrasion resistance of the paving block samples in the FG replacement level of 20% are 69%, 90%, 47% and 15 % higher as compared with the control sample respectively. It is reported in the earlier works the replacement of FG by FA at level of 20% by weight suppress the alkali-silica reaction (ASR) in the concrete. T...

The thermo-elastic properties of produced brick samples in various WSW amounts are investigated. At 30% WSW replacement with LPW in the brick sample the thermal conductivity value is effectively reduced and the reduction in the thermal conductivity value of brick sample at 30% WSW replacement with LPW is about 38.9% as compared with control sample. The energy conservation in buildings by using LPW and WSW in masonry brick material production having low thermal conductivity reduces energy requirements. A strong relationship is also found among the thermal conductivity, unit weight and ultrasonic pulse velocity values of brick samples produced. It shows a potential to be used for walls, wooden board substitute, alternative to the concrete blocks, ceiling panels, sound barrier panels, absorption materials etc.

Tekil temellerin boyutlarinin el veya bilgisayarli cozumlerinde, tecrubeli bir tasarimci tarafindan baslangicta yaklasik temel boyutlarinin tahmin edilmesi zorunlulugu bulunmaktadir. Baslangic temel boyutlarinin tahmininden sonra, uzun zaman alan deneme-yanilma proseduru takip edilerek boyutlar bulunmaktadir. Gelistirilen GA programinda baslangic temel boyutlarinin tahmin edilmesine gerek kalmadan, tekil temel hacmi minimize edilerek, en uygun temel boyutlari cok kisa surede bulunmaktadir. Klasik metotlarin aksine, GA temel taban boyutlari ile yuksekligini eszamanli olarak hesaplamaktadir.

It has not been used in concrete making applications due to its large amounts of free lime and sulfate contents. The fly ash in these plants is dumped in landfills, causing serious environmental hazards. Fly ash is disposed to the landfills by belt conveyors after being humidified with water. Therefore, the fly ashes humidified in the landfill areas are hydrated in nature. This hydration is further intensified in landfills by rain and snow. Thus, the free lime content of fly ash decreases due to its long hydration process. In this work, the lightweight masonry blocks were produced by mixing normal and hydrated fly ashes or normal, hydrated fly ash and lime without Portland cement. The compressive strength, water absorption, sorptivity, density, porosity, and thermal condu...

The correlations are established between the direct UPV and indirect UPV in the concrete casting direction as well as in the horizontal direction and semi-direct UPV measurements via statistical analysis. The statistical analysis reveals that the average value of direct UPV is 9%, 4%, and 4% higher than the average of indirect UPV in the casting direction, indirect UPV in the horizontal direction, and semi-direct UPV, respectively. The average value of indirect UPV in the horizontal direction is 5% higher than that in the casting direction.

A large amount of limestone powder wastes (LPW) are obtained in the quarrying operations of limestone and they are not used in the industries because of their fine nature. This paper presents a parametric experimental study which investigates the potential use of LPW and waste glass powder (WGP) for producing new low cost brick sample for the masonry units. The minimum cement amount for brick samples with LPW and LPW-WGP combinations, satisfying minimum compressive and flexural strength required in relevant international standards are found by making mix trials. The compressive strength and flexural strength, unit weight and water absorption values are obtained from the brick samples prepared and tested with the relevant international standards. The compressive strength and flexural strength and modulus of elasticity of brick samples with LPW-WGP combinations effectively are increased. Test results show that LPW and LPW-WGP combination provides results which are of potential to be used in producing economical new brick material for load-bearing masonry units.

The technique can be used for pre-estimation purpose for materials developed in a laboratory. Simple analysis of time-temperature curves for the specimens allows fair comparison of their effective thermal transmittances (or R-values) under specified conditions. The specimens used for sample calculation procedure are the ordinary concrete and the concrete with stripped scrap-rubber. The results show that R-value of ordinary concrete is enhanced nearly by 25% with addition of scrap-rubber.
