Dry application papercrete

摘要

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.

主权项

1. A dry papercrete mix comprising a component comprising pulverized dry cellulose/paper pulp, said pulverized dry cellulose/paper pulp comprising a mix of fiber material and sand and/or glass particles of a size to pass through a 2 mm mesh screen in which at least approximately one-half of the sand and/or glass particles desired in said dry papercrete mix is retained in said mix of fiber material and sand and/or glass particles by adhesion to said fiber material, said dry papercrete mix further comprising additional dry sand and/or glass particles and dry Portland cement and/or a mixture of Pozzolana and lime, wherein the formulation of constituent materials is in the proportion of approximately
30 pounds of cellulose/paper fiber, 94 pounds of Portland cement, 50 pounds wood chips and sawdust, 100 pounds sharp sand and/or glass particles, wherein a volume of said Portland cement and said sharp sand and/or glass particles is replaced by a substantially equal volume of a mixture of Pozzolana and lime in a ratio of approximately 3:1, and ½ cup dry soap or detergent.
