The present study proposes to evaluate in a comparative way the influence of the addition
of Portland Cement on the physical and mechanical properties of a soil sample collected in the
metropolitan region of Manaus-AM. For this purpose, consistency and granulometry limits have been
tested for characterisation; compaction, to obtain optimal humidity and maximum dry apparent
specific mass, and finally, test for Índice de Suporte Califórnia – ISC and expansion. The
comparative analysis was done by interpreting the results obtained with the soil in the natural
condition (SN) in front of samples with addition of 3% Portland cement (SN + 3% CP). The results
point to little influence on the physical parameters, however a 563% improvement in ISC.
