The correction of alumina is done with the help of bauxite or aluminous laterite. Mineralogically these rocks contain such aluminous minerals as gibbsite (Al2O3·H2O), boehmite (Al2O3·H2O), and diaspore (Al2O3·H2O).

However, the use of laterite soil along with natural pozzolana and cement in making bricks enhanced its hardened performance as comparing with cement stabilized laterite soil based brick. (Meukam et al., 2004). The influence of stabilizer on the performance of laterite soil based bricks is presented in Table 3.
