Material Properties of Rammed Earth Prepared from Illitic-Kaolinitic Clay
Authors: , ,
Abstract: The rammed unfired earth is one of the most eco-friendly materials, because the energy requirement for design is lower than the energy required for masonry brick structures. This paper is devoted to the characteristics of the rammed earth that is very much needed to design structures from this material. First, attention is paid to the preparation of test specimens from clay, sand and water. Dimensions of prism specimens for material testing are 40 × 40 × 160 mm. Creep measurement is performed on specimens of 70 mm length and octagonal cross-sectional area with distance of oposite sides of 20 mm. Secondly, the measurement procedures and the results of material tests of compressive strength and tensile strength in bending are presented. Third, determination of shrinkage and shrinkage is described and reported for a particular mixture. Material properties such as strength and modulus of elasticity are closely related to creep and are also listed. At the end, the advantages and disadvantages of the rammed unfired earth are discussed in terms of acquired material properties.
