  • Patent number: 10280331
    Abstract: A curable liquid composition, such as an alkyd paint or resin, contains a binder curable by oxidative crosslinking, a siccative compound for catalyzing oxidative crosslinking of the binder, and a matting agent. The matting agent is a precipitated silica, with a surface area, measured by BET, of 250 m2/g or less, a precipitated metal silicate such as Ca, Mg or Al silicate, or a mixture, and may be amorphous in nature. The siccative compound is a transition metal chelate complex comprising a ligand, such as an iron- or a manganese-based chelate complex. The compositions are capable of oxidative curing, within acceptable times, to form a cured solid, such as a coating, having a matt finish.

    Abstract: A dry papercrete mix is formed by preparing a wet pulp of fiber material such as newsprint and sharp sand by mixing sand, fiber material and water in a batch or continuous mixer, drying the pulp to a moisture content below that which will cause a reaction with Portland cement and adding additional sand and/or pumice and Portland cement. The resulting dry mix can then be handled, stored and used in the manner which is conventional for concrete. The dry papercrete mix can also be applied by pouring the dry papercrete mix into a form in a dry state and injecting water into the dry mix until the mix is sufficiently wetted without mixing in the manner common for concrete. Structural modules and a technique for joining them into a structure are particularly appropriate to the use of dry application papercrete.
