Cement-lateritic gravels mixtures: Microstructure and strength
Since the compressive strengths are in the range 1.45–3.1 MPa and the CBR values are higher than 160%, the studied cement-lateritic mixtures are suitable for base course construction [3]. 4. Concluding remarksCement additions to lateritic gravels led to the formation of a homogeneous microstructure and improved the mechanical strength.
