This paper presents the partial results of a research that intends to blend science of materials, earth construction and theenvironment. The research looks into the soil-cement brick technique, also known as BSC (for its Spanish acronym), for thepossibility of improving its structural performance and durability, by using geopolymerized earth brick mixes, replacing bothpartially and totally the use of Portland cement, in order to diminish CO2 emissions into the atmosphere.In order to prepare thedifferent mixes, a characterization of ready-for-disposal soil was carried out using X-Ray Diffraction (XRD); sodium hydroxideand type-F fly ash were then used. Three types of mix compounds were designed and tested for breakage and compressionstrength in local dedicated construction-material laboratories. Two of these compounds passed, and even surpassed, thetests for Colombian-normative for 28-day-old soil-cement bricks (earth bricks stabilized with Portland cement).The abovegeopolymerized earth bricks will be used in the construction of sustainable welfare housing in Medellín, Colombia. Sustainable construction; geopolymer; fly ash; soil-cement, heritage. |
