Effect of Treatment with Different Classes of Cement on the Geotechnical Properties of Soils: Case Study of Red Soil in the M'sila Region, Algeria

This article showcases the findings of an experimental study conducted on a red siltclayey taken from the site of Chaaba Elhamra (M'sila region, Algeria) for the purpose of being used for the building of road embankments and pavement layers.This experimental research aims to evaluate the geotechnical characteristics of this red soil, both before and after being treated with two classes of cement (CEM-II/B-L 32.5 N and CEM-II/B-L 42.5 N), and to analyse the impact of the cement class on its geotechnical properties.The experimental program included identification tests as well as Proctor compaction, CBR, and unconfined compression tests.The interpretation of the results has taken into account knowledge acquired from the literature.The findings showed that the percentage of cement had a beneficial effect on the geotechnical characteristics of this red silt-clay.Moreover, they highlighted that the type of cement did not have a great influence on the physical parameters, the compaction parameters, and the CBR indices.However, it was observed that class 42.5 cement had a much greater effect on UCS values than lower class 32.5 cement.
