Comparison 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 [1-3]. 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 [4-6].
