The effect of cement types on microstructures of lateritic soil has been evaluated in this research. The aim of this study was to determine the behavior of the textural characteristics of the lateritic soil before and after treated with cement types. Minimum and maximum quantity of cement required to achieved a substantial changes in thirteen different mixes of lateritic- cement at varying percentage of cement content were produced The natural lateritic soil and lateritic soil with varying percentages (0, 3, 6, 9 and 12%) of the three types of cement namely CEMENT I, CEMENT II and CEMENT III used in the study were examined through Scanning Electron Microscopy (SEM). The microstructures of untreated and treated lateritic soil with cement types examined through SEM revealed the surface texture, bond formation and mineral structure of the specimens which suggests that the improved samples are adequate for engineering use
