STUDY OF THE THERMOCHEMICAL AND MECHANICAL PROPERTIES OF LATERITE BRICKS STABILISED WITH CEMENTS

In this work, we characterised the thermophysical parameters of Thicky laterite as a function of water content and also as a function of the cement content in the mix. For laterite with a diameter less than or equal to 1.25 mm, the thermal conductivity is 0.388 W/m.K for a water content close to 0%, this thermal conductivity increases to 87.37% for a water content of 3.46%. Laterite without cement has a strength of 2.309 MPa, this strength increases by 4.80 %, 13.16 %, 18.45 % and 47.82 % respectively when 4 %, 6 %, 8 % and 10 % cement is added to the laterite. The flexural strength changes with the cement content of the mix, from 0.24 MPa for simple laterite to 0.510 MPa when 10% cement is added to the laterite health.
