ABSTRACT
The present work is being developed on the scope of the Department of Civil Engineering,
Constructive System Division, at the University of Brasilia. The present housing problem in Brazil is widely known due to the existence of numerous homeless people in rural areas and also in urban centres. The most recent figure indeed points out a shortage of 5.6 million, including metropolitan and rural areas (Planning Ministry – PNUD/SEPURB, 1995). Moreover, quite frequently, the developed product for the proposals (low-cost housing) does not offer its user the expected quality or performance. The objectives of this work are performance evaluation of clay-expanded mortar compounded panels for rational masonry applied to low cost housing in Brazil. Strength and thermal performances, as well as the quality and the rationalization, were analysed, select by the requirements comprised in the guideline ISO – DP 6241. Some tests were performed: safety strength (soft body, hard body, suspended piece and closure doors) and the thermal conductivity index. The thermal performance analysis results of the internal temperature presented were obtained with a study simulation of the constructive system. The results were compared with conventional masonry constituted by ceramic blocks..
Key words: performance evaluation; clay-expanded mortar compounded panels; in-use structural performance; thermal performance; qualitative and rational masonry; construction systems; low-cost housing.
