Collaborative disposal of multisource solid waste: Influence of an admixture on the properties, pore structure and durability of foam concrete

Köpük Beton Üretiminde İnşaat Yıkıntı Atığı İnce Agregası Kullanımı ve Optimum Su/Çimento Oranının Belirlenmesi

“…Uçucu kül katılarak tasarlan köpük betonların dayanımı 0,34 ile 20 MPa arasında değişir birim hacim ağırlıkları 500 ile 1500 kg/m³ arasında olduğu vurgulanmaktadır [21,[25][26][27][28][29]. Song et all (2021), Nambiar ve Ramamurthy (2007) yaptıkları çalışmada köpük betonun kararlılığında; karışıma giren su ve ilave edilen köpük miktarı yanında katı bileşenlerinin etkili olduğunu ortaya koymuşlardır [30][31]. Yüksek miktarda ince malzemenin kullanılması ile büzülme değerlerinin artmasından meydana gelen iç gerilmeler, bünyesinin mukavemet değerlerini aşması halinde büzülme çatlakları meydana gelmektedir.…”

Preparation and Application of Slag‐Based Catalyst for Steelmaking

“…One such catalyst is manganese-based, which has garnered attention due to its excellent low-temperature denitration activity. [21][22][23] Manganese-based catalysts exist in two main forms based on different loading methods: unsupported manganesebased catalysts and supported manganese-based catalysts. [24][25][26] Manganese is a variable-valence metal capable of undergoing DOI: 10.1002/srin.202300755…”

A study on the catalytic performance of the ZrO2@γ-Al2O3 hollow sphere catalyst for COS hydrolysis

“…[16][17][18][19] However, the method has certain drawbacks in which there is limited adsorption between the oxygen-containing functional groups on the surface of the carbon sphere template and the metal cations, resulting in the formation of very thin shells of hollow microspheres that are prone to collapse. [20][21][22][23][24] Zirconium dioxide is the only metal oxide that is simultaneously acidic, basic, oxidizing and reducing and is a p-type semiconductor material that readily generates oxygen vacancies and interacts with active components as a catalyst carrier. [25][26][27][28][29] Therefore, the catalyst supported by it exhibits more excellent performance than the catalyst supported by other substances.…”
