Innovative soil-cement block eliminates settling mortar

Thursday, 19 December 2013

A work deals with 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.

A group of researchers from the Universidade Federal Rural do Rio de Janeiro and the Escola Superior de Propaganda e Marketing, Brazil, and the University of Wollongong, Australia, developed a fitting construction component aiming the construction of masonry without mortar.

Water absorption parameter must be targeted by future research

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 developed and prototypes were conformed in three soil-cement mixtures showing production feasibility. Tested according to the related standards, the prototypes were submitted to resistance of 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 research in order to improve the mixture composition.

The study is published in: Construction and Building Materials, Volume 52, February 2014, pp 391-395
