Influence of additives on the structural performance of cement-stabilised rammed earth

The influence of additives on the structural behaviour cement-stabilised rammed earth was investigated through an experimental programme based 13 different mixes with varying cement contents (6, 8 and 10% by weight) three types (superplasticiser, air-entraining agent (AEA) hardening accelerator). In total, 156 specimens were fabricated tested at 7 28 days in order to compare their compressive strength other properties such as stress–strain relationships, shrinkage workability. results highlighted essential role increasing material. Specifically, 6%, 8% corresponded, respectively, increases 41%, 80% 92% compared reference mix a mean 1.15 MPa. AEA found be most effective additive for strength, obtained strengths up 2.93 MPa (an increase 155% mix). efficiency each evaluated strength/cost ratio. addition, overall comparison shrinkage, deformation, cost workability performed using analytic hierarchy process. Finally, mechanical requirements various codes.
