Alternative binding material for construction in the tropical climatic conditions prevailing in Angola
Main Article Content
Abstract
Clay soil material can contribute to improved performance in buildings, taking into account aspects related to the sustainability of materials. Since Portland cement production contributes significantly to greenhouse gas emissions, reducing the clinker factor through the application of formulations that consider local resources can improve the quality and sustainability of buildings.
This study describes the production of pozzolans from the controlled combustion of biomass sources, such as African palm bark and sugarcane, when mixed in certain proportions with soil and lime. Clay material is also a resource historically used by rural residents. This work also addresses the potential use of clay when thermally activated as pozzolan.
Proposals are presented that contribute to improving materials and the quality of new buildings.
