Soil-Cement Ratio and Curing Conditions as the Factors of ...

Soil-concrete is widely used to strengthen the foundation footings, in the construction of roads and railways, as well as for the production of bricks and pavement tiles. One of the most important physical and mechanical properties of soil-concrete is the compressive strength. We carried out a study of soil-concrete strength depending on its curing conditions and percentage of cement.
