El uso de tierra modelada en la intervención de componentes constructivos de adobe

Abstract

The article analyzes restoration and conservation processes whose origins stem from the ancient construction system known as cob. The technique was improved by stabilizing the soil with calcium hydroxide and subsequently densifying it. It wastested against compression, retraction, absorption and weathering at UAM-Xochimilco, and showed remarkable results in being able to increase its resistance and durability. The procedure was applied in several national and international workshops and, more recently, in communitarian efforts to restore damaged adobe houses affected by the earthquakes that hit the south of Mexico in September 2017. Theproposed strategy is easy to learn and apply, and uses a minimum of technical and material resources.
