<p>The object of the invention is to get the concrete as well to be of good workability as also tough at same time and in addition desiderable for its several other properties, such as e.g. the unit weight and thermal capacity. In the method according to the invention as components of the concrete in variable proportions are used Portland cement or other hydraulic binders, to its particle size below 8 mm being aggregate as well as to their length in continuous grading or gap-graning distributed natural fibres, e.g. wood fibres, which together with the aggregate contain the main part or all of the water quantity required for the hydration of the binder.</p> |
