Compressive Strength Compressed Earth Blocks Using Slaked Lime/Cement of Combination as Stabilizer

Abstract

This study determines the compressive strength of compressed earth blocks using a combination of slaked lime and Portland cement as stabilizer. Stabilizer: earth mix ratio of 1:10, 1:12, and 1:14 is considered in the study. Stabilizer used in this study is composed of 50% slaked lime and 50% Portland cement. Soil used for the production
of blocks is taken from the quarry in Pindugangan, Iligan City. The blocks are fabricated using a locally manufactured block press. The block dimension is 100 x 150 x 300 mm (L x Wx H). Compressed earth blocks were tested for compressive strength at 7h, 14th, and 28h days. For 28 days of curing period, stabilizers: earth mix ratio of 1:10, 1:12, and 1:14 gives an average compressive strength of 5.75, 5.42, 5.04 MPa, respectively. The compressive strength of the different mix
ratio varies slightly. Lower stabilizers-earth mix ratio develops higher
