A method and a technique for producing precast-cast-in-situ lightweight rigid building assembled from the modified hollow core slab and sandwiched hollow block wall segments. Three methods are presenting for incorporating shear and flexural reinforcements as well as traditional prestressed reinforcements in the hollow core slab. The modified hollow core slab and the sandwiched hollow block wall segments are assembled in-situ by post tension to produce two way slabs and two way walls. The upper concrete fiber as well as the cast in-situ upper concrete topping of the traditional hollow core slab are replaced by only one fully composite cast-in-situ reinforced concrete topping layer. The present technique is greatly enhancing the mechanical properties of the traditional hollow core slab and the sandwiched hollow block wall panels as well as the assembled building.

摘要:
The present invention provides a method for producing a construction element which comprises partially curing an amount of vegetable oil, mixing said partially cured vegetable oil with an aggregate and then further curing said vegetable oil within said mixture. There is further provided a structural element comprising at least partially cured vegetable oil and an aggregate. A composition for use in the production of a reinforced construction element is provided, said composition comprising a vegetable oil, a graded aggregate and a fibrous reinforcing agent. Construction elements produced using the composition are described. A method for producing a reinforced construction element comprises mixing vegetable oil with a graded aggregate, mixing a fibrous reinforcing agent with said mixture of vegetable oil and aggregate, and then curing said vegetable oil within said mixture of vegetable oil, graded aggregate and fibrous reinforcing agent.
摘要:
Der ein Bindemittel enthaltende Baustoff auf pflanzlicher Basis PB (vorzüglich Miscanthus), enthält einen Mineralisator, der aus einer definierten anwendungsorientiert angefertigten Mischung M2 von Kalziumkarbonat CaCO 3 191 und Magnesiumkarbonat MgCO 3 191 besteht, was zu einer wesentlichen Verbesserung seiner chemischen, physikalischen und mechanischen Eingenschaften führt. Die Gewichtsanteile der diese Mischung M2 bildenden Komponenten liegen zwischen ca. 60 % und ca. 95 %, vorzugsweise zwischen 2/3 - 9/10 für das CaCO 3 191 und zwischen ca. 5 % und ca. 40 %, vorzugsweise zwischen 1/10 - 1/3 für das MgCO 3 191. Das Herstellungsverfahren des Baustoffes wird dadurch rationalisiert, dass der Mineralisator im Bindemittelwerk direkt nach festgelegten Angaben dem Bindemittel, bevorzugt Portlandzement der Güte 52.5, vorher zugemischt wird, um eine Mischung M1 zu bilden. Die Gewichtsanteile der die Mischung M1 bildenden Komponenten liegen zwischen ca. 50 % und ca. 90 %, vorzugsweise zwischen 6/10 - 4/5 für das Bindemittel und zwischen ca. 10 % und ca. 50 %, vorzugsweise zwischen 1/5 - 4/10 für den Mineralisator. Um den Erstarrungsprozess zu verbessern, wird dem Anmachwasser ein Fungizid-Präparat hizugefügt. Aus der Menge {PB + M1} ist ein Universalbaustoff herstellbar, der unzählbare Anwendungen erlaubt. Die Anwendungspalette wird noch dadurch vergrössert, dass genannter Menge ein weiteres anwendungsorientiertes Gemisch M3 in definierten Proportionen beigemischt werden kann (zum Beispiel Gips (z. B. für die Herstellung von Schnellbauplatten) oder ein Fliessmittel, um ein Extrudierverfahren zu erlauben (z. B. für die Herstellung von strangförmigen Elementen)).
摘要:
A backerboard sheet is for moist areas and includes a core having opposing first and second major surfaces, at least one moisture-resistant face layer on at least one of the first and second major surfaces of the core; and wherein the core comprises aerated concrete. The provision of aerated concrete for the core provides many key advantages over conventional backerboard sheets, such as gypsum greenboard or cementitious backerboard, for example. The at least one moisture-resistant face layer may include fibers, such as arranged in a woven mesh. The fibers may include at least one of glass, plastic, and metal. In addition, the at least one moisture-resistant face layer may further include a moisture-resistant material incorporating the fibers, such as a suitable resin, for example. The at least one moisture-resistant face layer may include first and second moisture-resistant face layers on respective first and second major surfaces of the core. The core may also have a generally rectangular shape defining a pair of opposing side edges and a pair of opposing end edges. The first major surface in some embodiments may have beveled portions adjacent respective opposing side edges.
