A new procedure to adapt any type of soil for the consolidation and construction of earthen structures: projected earth system

“…The most important advances in rammed earth construction using the "tapial" technique have centred on increasing the density and loadbearing capacity of the earth either by improving the compaction process by replacing earth rammers with small mechanical compactors (in the case of new buildings), or by using hardeners, selecting specific kinds of materials and reinforcing them with natural or artificial fibres (10)(11). In the context of restoration, attention is focussed on in situ consolidation of such materials (12), based on the fact that clay-rich soils encountered while building roads or digging foundations must be stabilised and/or consolidated to prevent problems caused by changes in humidity.…”

Experimental analysis of Pressed Adobe Blocks reinforced with Hibiscus cannabinus fibers

“…To improve the mechanical strength, impermeability and the durability of locally produced adobe, in general, small amounts of quicklime or natural fibres are added to the soil matrix [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The use of local natural fibres, especially in developing countries, is more beneficial for the population as fibres are locally available in abundance and their productions are of low cost and low consuming energy besides are not polluting.…”

Fibre reinforcement in earthen construction materials

“…In previous studies, it was found that adding fibres to rammed earth or to composite soils either decreased the unconfined compressive strength (UCS) (Maniatidis and Walker, 2003;Schroeder et al, 2005) or gave a small increase at low-fibre contents (Bouhicha et al, 2005;Galán-Marín et al, 2010;Ghavami et al, 1999;Houben and Guillaud, 1994;Marandi et al, 2008). The effect of fibre content on UCS was possibly governed by the clay content of the soil; soils with larger clay contents responded to increased fibre content with a higher UCS, while more sandy soils showed a lower UCS with increased fibre content.…”
