    摘要： Concrete slab designed for the construction of a billiard table, produced with a cement mix comprising, as a special hydraulic binder, a mixture of Portland cement, aluminous cement and antishrink additive, a fine sand aggregate from 0 to 8 mm, a selected gravel aggregate from 8 to 20 mm, and a filler of long fibers of synthetic material; said concrete slab also comprises a metal reinforcement and, furthermore, a filler of material having a high specific weight, sufficient to bring the relative specific weight of the whole slab to a value exceeding 2.6; a thin protective layer of shockproof coating being moreover applied onto the surface of the finished slab. The filler of material with high specific weight consists of basaltic gravel and/or baryte, introduced in the cement mix, or of a filler of steel rod pieces of the FeB 44 type with improved adherence, anchored to said metal reinforcement.

    摘要： The mass is structured on the basis of calcium aluminate cement, aggregates, water and chemical additives that modify the characteristics of the concrete. This mass uses magnetite, hematite or steel shot as an aggregate, with a highly continuous granulometry so as to achieve perfect consistency in the mass (Fuller's curve), accompanied by a high density, decisive factors for an optimum barrier effect against radiations. It can withstand high temperatures without there being any structural loss and it therefore maintains the barrier effect. The mass is suitable for producing poured concrete, concrete for bricks, and mortar, for use in the building of radioactive enclosures in which energies above 450 KeV, etc. are handled.
    Furthermore, prefabricated blocks of mixed mass, one of high density with great heat accumulation capacity and the other with the opposite effect, i.e. of low capacity and low conductivity, enable the prefabricated blocks to emit the thermal energy from the same faces by which they absorb it.
