The disclosed method proposes, for the mixing of a solid and dry granular mixture and a liquid bituminous binder, the solid and dry granular mixture being a mixture of two fractions of constituents, one of which is a coarse fraction including aggregates, the other fraction a fraction of submillimeter fines, that the mixing includes at least two consecutive mixing steps: an aggregate-preimpregnation step, consisting of mixing the coarse fraction of the granular mixture with a part of the bituminous binder, in a quantity at least sufficient for coating the aggregates and at least partially filling the open pore spaces of the aggregates; and a covering mixing step, which consists of mixing the preimpregnated coarse fraction of bituminous binder and originating from the first mixing step, with the balance of the bituminous binder, required for the manufacture of the electrodes, and with the fraction of fines of the granular mixture.

Method of forming a concrete slab to reduce or eliminate control joints includes preparing a substantially flat base, overlaying one or more barriers on top of the base, placing a concrete mixture on top of the barrier(s) and base to form a concrete slab, and allowing the concrete to cure without forming control joints. The base is prepared with a flatness of about inch over 10 feet. A side edge is prepared along a periphery of the concrete slab by extending a vapor barrier from a bottom surface of the slab up the side edge toward a top surface of the slab and covering the side edge. A plurality of post-tensioning cables are positioned to extend through the slab and configured to compress and assist in controlling accelerated displacement of the concrete slab during curing and shrinkage. The concrete slab is formed of an evenly gradated and low slump concrete having high fiber content, minimized cement content, and maximized size of large aggregate.

Dry mortar mixture characterized by a glass mixture of expanded glass beads with a grain size d/D 0/8, mixed in a ratio of between 1:1 and 1:3, with a binding mixture of hydraulic binders and stone granules in the weight ratio of 1:2 to 1:4. The glass has a discontinuous grain distribution. For the glass mixture the fractions 0.5/1.0 and 2.0/4.0 are present while a fraction intermediate other fractions are absent. Preferably the fractions 0.25/0.5 and 1.0/2.0 are absent. For the glass mixture preferably all grain sizes between 1.0 and 2.0 mm are absent. The grain size distribution is around an average, so that an open structure is obtained.

The invention relates to an additive mixture for addition to a building material covering mixture for forming a composite covering system for the floor, wall, or facade area, which additive mixture reduces the thermal conductivity or thermal dissipation of covering systems, in particular the thermal dissipation through objects and sub-bases coated with the covering system, in such a way that walking on the sub-base provided with the covering system is no longer associated with a sensation of cold feet. This is achieved in that the additive mixture has a proportion of between 50% wt and 95% wt of Muscovite mica.
