More recently there has been Great interest in the production of lightweight building components which can be used for the purpose of thermal insulation.The use of such components and buildings have a great advantage and cause great reduction in the energy required for heating and cooling consequently results cost reduction to a great extent , especially prevailing hot dry climatic condition of Iraq. Its thus aimed in this thesis to study properties of two types of polystyrene insulation concrete which can be used for thermal insulation .Such type of lightweight concrete is very needed in...

The research is concerned with a new type of ferrocement characterized by its lower density and enhanced thermal and physical properties such as compressive and flexural strength.The work can be divided into two main parts; in the first part experiments where maid to determine activity index of two types of active pozzolan, namely micro silica ad indigenous calcite and grinded feldspar. Several mortar mixes where prepared to determine the optimum amount of cement and lightweight aggregate (namely local porcelain and polystyrene aggregate). The experiment showed that porcelain are more...

Les grandes industries sont à l'origine de la pollution de l'environnement et du réchauffement de la planète. Les scientifiques s'efforcent donc de trouver des moyens d'utiliser les déchets industriels comme substitut aux ressources fondamentales afin de maintenir l'équilibre naturel et de minimiser les déchets industriels. Le ciment est la principale source d'émissions de dioxyde de carbone et de chaleur élevée pendant le processus de production dans l'industrie du bâtiment. Comme certains déchets industriels contiennent des matériaux de silice et d'alumine, le monde s'est...

Large industries are causing environmental pollution and global warming. Thus scientists are focusing on finding ways to utilize industrial waste as a substitute for fundamental resources in order to maintain the natural balance and minimize industrial waste. Cement is the primary source of carbon dioxide emissions and high heat during the production process in the building industry. Because some industrial wastes contain silica and alumina materials, the world has turned to geopolymer mortar, which is made from these wastes (such as fly ash, slag, etc.) and has a low production cost and high...

Die Großindustrie verursacht Umweltverschmutzung und globale Erwärmung. Daher konzentrieren sich Wissenschaftler auf die Suche nach Möglichkeiten, Industrieabfälle als Ersatz für grundlegende Ressourcen zu nutzen, um das natürliche Gleichgewicht zu erhalten und Industrieabfälle zu minimieren. Zement ist die Hauptquelle für Kohlendioxidemissionen und große Hitze während des Produktionsprozesses in der Bauindustrie. Da einige Industrieabfälle Siliziumdioxid und Tonerde enthalten, hat sich die Welt dem Geopolymermörtel zugewandt, der aus diesen Abfällen (z. B. Flugasche, Schlacke...
