EXPERIMENTAL STUDY FOR STRUCTURAL PERFORMANCE EVALUATION OF EARTH WALLS REALISED WITH INNOVATIVE TRADITIONAL TECHNOLOGIES
Abstract
Traditional building materials based on primary natural resources can be used for green housing concepts with energy eco-efficiency and the health of the living space, representing a special group of innovative materials for the construction industry. They are developed by using and improving the local, traditional technologies and concepts applied on basic, natural raw materials (clay and sand, wood, straw, wool, etc.), for the general purpose of creating the living space in a sustainable, environmentally friendly manner. Thus, construction products like adobe bricks, structural or non-structural elements (bearing or/and partition walls, floors, etc) or even complete structures, including the corresponding finishing elements, are realised. The domain allows the valorisation of the vernacular urban heritage of the Romanian space, in full agreement with the European and national strategies to encourage natural, ecological and nonpolluting materials, based on accessible raw materials, non-polluting, with low degree of toxicity and low carbon dioxide emissions and, at the same time, with a high degree of recyclability and ability for conversion to new destinations. The current study is focused on preliminary experimental laboratory testing, performed on several types of earth walls, developed by using diverse clay-based mixes, with or without additional materials as disperse or local placed reinforcement, in order to evaluate their bearing potential as structural, load-bearing system for an ecological housing concept. The initial results and the corresponding comparative analysis are confirming the positive contribution induced by reinforcing the elements, both for the bearing performance and axial contraction reduction and crack prevention as well.
