Determinação da umidade ótima de misturas de solo-cimento por prensagem manual para obter tijolos.

Abstract

Blended Portland cement CP-II-E and a non-plastic sand-clayey soil on traces 1:10; 1:11; 1:12 were utilized to obtain soil-cement bricks. The compaction employing the same manual press utilized for the soil-cement bricks showed to be adequate as a method for optimum moisture content determination. The optimum moisture content values were determined for all mentioned traces. It was observed that the optimum moisture content showed to be greater than the moisture content needed to obtain maximum compressive strength and minimum water absorption values, but the quality of all soil-cement bricks was not affected.
