Comparision of the physical properties of earth construction units: adobe, tapial and champa. The importance of its use in the peruvian highlands

Between 30% to 40% of constructions in Peru are on earth, in this percentage must include the archaeological monuments. Among the areas with highest percentage of building systems on earth is in the Peruvian Highlands. This is because knowledge inherited from generation to generation, location and socioeconomic level. This document is intended to compare 3 construction units: adobe, rammed earth, and champa, which are commonly used in areas of higher altitude. Adobe, is a block composed of sand or earth, water, clay and straw, forming a mixture that is poured into molds. The tapial, has the same mixture that is adobe, but the process block, in the area of construction by pouring the mixture into a drawer. The champa, therefore, is a fully extracted soil material, does not have any additive or additional material. These materials are based on vernacular of the Peru building systems, which are cultural heritage. It can be concluded that the three construction units are quite favorable for thermal resistance values. But in this specific case, it champa it has pretty impressive data, gets 0, 25W/m· K thermal conductivity as a material with high thermal resistance of 4.0 K·m/W. It is for this reason that, this document aims to demonstrate that although construction of ground units possess physical characteristics optimal, and thus is shown, because in the Peruvian highlands is not more used construction unit the champa
