Studying the Effect of Morcemcolor Cement as Stabilizing Material on Unconfined Compressive Strength on Compressed Earth Block Produced from Daquq Area, South of Kirkuk, Northen Iraq

Since the Mesopotamian civilization, one of the oldest civilizations in history, soil has been used to construct buildings that still stand today. Soil is undoubtedly one of the most widely used building materials in the world. Man built the first houses made of soil. Clay and soil are still used as building materials. However, some soils have problems and need to be treated by adding other materials, such as cement. Soil samples were taken from northern Iraq, specifically the Daquq area, south of Kirkuk. The method of work includes conducting laboratory tests of the raw components of the soil before preparing the samples. Then, preparing the models to make compressed earth blocks under a pressure of 15 MPa with or without the addition of Morcemcolor cement as stabilizing material, which represents colored, water-repellent, and additive mortar with mixed binders, characterized by high fineness and plasticity. Then, geotechnical tests are conducted for (7, 14, 21, and 28) days to determine the extent of its effect on the unconfined compressive strength (UCS). The results show that the use of cement increases the UCS, resulting in very strong and safe brick blocks for construction, according to the safety and security conditions for building materials
