Mechanical characterization of dry-stack masonry made of CEBs stabilised with alkaline activation
The increasing interest on earth construction as a sustainable building solution led to the development of modern earth construction techniques, in particular of masonry made of compressed earth blocks (CEBs). The traditional chemical stabilisation of the soil is a frequently used improvement process. However, such process increases significantly the embodied energy of the CEBs. This paper presents an alternative technique for the stabilisation of CEBs, based on alkali activation of fly ash. The mechanical behaviour of the CEBs and of the respective dry stack masonry is comprehensively investigated through an experimental program, during which this technique proved to be highly effective. ; The authors wish to express their gratitude to Mr. Pedro Esteves for his support in the experimental work and to Eng. Jorge Henriques, on behalf of the company PEGOP – Energia Eléctrica SA, for providing the fly ash. The financial support provided by the Portuguese Science and Technology Foundation through the project FCOMP-01-0124-FEDER-028864 (FCT-PTDC/ECM-EST/2396/2012) is also gratefully acknowledged. ; Fundação para a Ciência e a Tecnologia (FCT)
