MORTIER À BASE DE TERRE AMÉLIORÉ
The present invention relates to a method for spraying or injecting an earth-based mortar comprising the steps of: i) preparing the mortar by mixing: ia) earth derived from earth-working or excavation operations (quarry) or crushed deconstruction materials (concrete, brick, plaster, stone and mortar), but not derived from sand quarries nor aggregate quarries (virgin aggregates), and excluding topsoil, with a particle size less than or equal to 20 mm in a volume proportion in the range of 20 to 55%; ib) a binder comprising slag or metakaolin and, optionally, lime, in a volume proportion in the range of 15 to 50%; ic) a material having a silica content greater than 50% (by weight), an open porosity greater than 45% as measured by mercury intrusion porosimetry and a particle size smaller than or equal to 5 mm in a volume proportion in the range of 0 to 20%, id) aggregates with a particle size of between 2 and 20 mm in a volume proportion in the range of 0 to 20%; id) fibres in a volume proportion in the range of 0 and 30%; ie) crystalliser in a volme proportion in the range of 0 to 15%; and if) water in a volume proportion in the range of 5 to 25% ii) pumping the mixture obtained in i); and iii) injecting the mixture into a mould or spraying the mixture onto a vertical or horizontal surface.
