Floods and weather changes are affecting the homes of the people who live in open shores. The idea of the term amphibious houses is to provide a solution to the se people´s housing, preventing the loss of the houses in the floods. Objective. To evaluate the best mixture of cement and aggregates to develop a floating structure (slab) intended to be the base for floating houses. Methodology. A standard commercial mixture was taken as a base and other two mixtures were made in order to compare. In the mixture cement, common sand and 3/8 crushed were used. Three treatments with three replicas for each one were performed, completing nine tests. The experimental design used was a unifactorial design. Results. If a highly firm slab is aimed to be built, the mixture from proportion 1 is recommended. Proportion 3 is recommended for the opposite. Conclusion. If a formula to develop a resistant and stable slab is required, treatment 3 is recommended. It has 14.28% of cement, 28.57% of sand and 57.14 of crushed.esCorporación Universitaria LasallistaFacultad de IngenieríasViviendaVivienda anfibiasCementoHormigónMateriales para la construcciónMezcla de cemento y agregados: una alternativa para la elaboración de una placa de hormigón usada en casas anfibias o flotantesMixture of cement and aggregates: an alternative to elaborate a concrete slab to be used in amphibious or floating housesMistura de cimento e agregados: uma alternativa para a elaboração de uma placa de concreto usada em casas anfíbias ou flutuantesArticle
