Contribution To Study Of The Influence Of Lime Addition On The Thermo-Mechanical Properties Of Hajira Clay-Based Adobe.

Abstract

This research topic consists of using local materials to build a construction low consumption. The aim of this project is to evaluate the behavior of the El hadjira clay-based Adobe by adding lime in different percentages. This technical study is based on the application of tests for the mechanical and thermal characterization of the latter. We made some samples of the tested Adobe, which gave good thermal and mechanical properties, in order to try to use them in the construction field. We set the percentage of gravel and clay, and that of the addition of stabilizer (lime) to 1% up to 5% by mass.

The results of these tests have shown that the percentage increase of lime is useful to improve the mechanical behavior. Compressive strength increases up to 43% compared to the reference sample. The results also show that the thermal properties remain very good which ensures a construction low consumption.
