    Abstract: The invention relates to a preparation of a concrete having a compression resistance of at least 400 MPa and a fracturation energy of at least 1 000 J/m . A mix containing substantially cement, fine sand, amorphous silica, crushed quartz, steel wool, a fluidifying agent and water in specific proportions is mixed and, after setting, the concrete is fired at a temperature of at least 250 DEG C. The figure is a micrography showing the microstructure of concrete according to the invention. The invention provides particularly for the making of concrete parts in replacement of steel, for example anchoring heads for prestressed cables.

    Abstract: A premixed ultra-light sandless mortar for use with clay and concrete tiles. The mortar uses vermiculite or perlite aggregate in place of heavy aggregates such as sand. The mortar cement is made from portland cement, lime, air entraining agents, and water repelling agents. The resulting compound retains large amounts of moisture which increases hydration time resulting in improved bonding strength, and increased tile uplift strength. The light weight of the mortar also allows a full bed of mortar to be laid on the roof with the resulting benefit of an addition insulating layer for the building. The mortar is suitable for roofing or floor tile applications.

    Abstract translation: 一种用于粘土和混凝土砖的预混超轻型无砂砂浆。 砂浆使用蛭石或珍珠岩骨料代替沉积物如沙子。 砂浆水泥由波特兰水泥,石灰,加气剂和防水剂制成。 所得到的化合物保留大量的水分,这增加了水合时间,从而改善粘合强度,并提高了瓷砖提升强度。 砂浆的重量也允许将全床砂浆铺设在屋顶上,从而获得建筑物的加成绝缘层的益处。 砂浆适用于屋顶或地板砖应用。
