Our ancestors used earth as a primary building material, and from prehistoric times, they adopted clever yet simple construction techniques. Mud, which is widely available locally, is a valuable material due to its flexibility in processing and energy efficiency. Mud has been used for construction in India and elsewhere for a long time, and even today, mud wall construction is common in rural parts of India. Although mud is prone to degradation from rain and wind, it is a reliable material with advantages such as affordability, abundance, and good fire resistance. For low-rise and low-cost buildings, mud remains a dependable material. Researchers have discovered methods to enhance mud's quality and durability through stabilization processes to overcome the disadvantages of pure mud construction. In this study, durability aspects of cement-sand-soil mortar are explored. Soil with varying ranges of clay content is considered. Different amounts of cement content are added to obtain different proportions of cement-sand-soil mortar. Durability aspects of mortar that are explored by conducting tests like workability, compressive strength, sulfate-resistance test, acid resistance test, drying shrinkage test, and water absorption test are determined for cement-soil mortar and compared with cement mortar. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.Acid resistance testCement-soil mortarClay soilDrying shrinkage testDurability testsStabilized soil mortarSulfate-resistance testWater absorption testStrength and Durability Properties of Early Cement-Soil Mortar
