Abstract
Composition comprising water- and air-hardenable binders and its use notably to the preparation of a product having the aspect and the properties of a natural stone. Composition comprising water- and air-hardenable binders, exhibiting after hardening properties comparable at least to those of a natural stone or of a concrete, characterised in that it includes, as binders: natural and air-borne hydraulic lime, and moulding plaster.
Claims18
A composition comprising water- and air-hardenable binders, exhibiting after hardening properties comparable at least to those of a natural stone, the composition consisting essentially of:
- a mixture of natural and air-borne hydraulic lime and plaster of Paris as the binders, a proportion of weight of lime and plaster ranging between 25% and 75% of both the binders;
- calcereous and/or siliceous mineral loads, a quantity of the mineral loads ranging between 0.5 and 6 times of both the binders;
- and
- a water-reducing adjuvant, a proportion in weight of the adjuvant ranging between 0 and 5% of the binders.
A composition having an aspect of natural stone, comprising:
- 315 Kg/m3 hydraulic lime;
- 315 Kg/m3 plaster of Paris;
- 750 Kg/m3 fine calcareous load;
- 450 Kg/m3 siliceous load;
- 80 Kg/m3 siliceous fines;
- 18 Kg/m3 fluidiser adjuvant;
- 1-5 Kg/m3 other adjuvants;
- and
- 300 Kg/m3 water.
A composition having an aspect of natural stone, comprising:
- 500 Kg/m3 hydraulic lime;
- 500 Kg/m3 plaster of Paris;
- 750 Kg/m3 fine calcareous load;
- 20 Kg/m3 fluidiser adjuvant;
- 1-5 Kg/m3 other adjuvants;
- and
- 350 Kg/m3 water.
