Feasibility study of the manufacturing process of soil-cement blocks for the construction of masonry aiming to eliminate the settling mortar application
The growing industrialization of the construction materials, the evolution of the construction techniques and ease for conveyance, broadly speaking, eliminates the need to use local materials for construction. However, the earth still presents itself as a material with the potential to reintroduce the old and healthy construction habits, yet without precluding the search for technical innovations consistent with good environmental practices, and that may contribute to the formulation of simpler and cheaper processes. The current work developed the morphology of a new component of construction made with an easy acquisition and low cost material: soil-cement, a material and procedure proven, tested, and regulated. The redesign of a new construction component aims to facilitate the rise of the masonry through an innovative construction process, in which the settling mortar can be eliminated with a perfect fitting system. With the fitting block designed, the mould for pressing was then developed and prototypes were conformed, experimentally, in three soil-cement mixtures showing production feasibility. The prototypes were tested according to the related standards, being submitted to tests of resistance to compression, water absorption and sizing. The results showed that only the water absorption parameter did not comply with the standards and therefore must be targeted by future researches in order to improve the mixture composition.
