In Brazil, ceramic blocks have a significant share of the masonry construction market. Thus, an experimental testing program was devised to determine physical and mechanical properties from different regions Brazil. The included five Brazilian states ten producers, studied were absorption, material density, efflorescence, abrasion, compressive strength, resistance towet-dry cycles. purpose dete...

Abstract Limestone wastes have accumulated in large quantities countries all over the world. To reduce this materials work is presented. The goal of paper to study influence limestone powder on physical and mechanical fired clay bricks. It as replacement clay, varying content 5, 10, 15 20 wt % . water / soil ratio constant 0.3. Three stages firing are presented achieve maximum temperature. firs...

A common decay scenario in old and new buildings was simulated: the effects on masonry structures of salt efflorescence or subefflorescence produced by the rise of saline solution. Eight different types of masonry wall each made up of a combination of different construction materials (brick, calcarenite and four types of mortar were combined as follows: pure lime mortar, mortar + air entraining...

The sustainability goals of the developing world have led many industries to recycle their wastes and reduce emitting greenhouse gases. To contribute these environmental responsibilities, this study has focused on development eco-friendly binder materials from regional ground tuff marble by activation Na2SiO3 NaOH or slaked lime (Ca(OH)2). results show that alkali-activated composites tend expa...
