| 61 | Concrete admixture additive | US11979601 | 2007-11-06 | US20080071040A1 | 2008-03-20 | Theresa Tsai |
| A new family of concrete admixture additives can be derived from reacting a mixture of olefins/cyclic olefins-maleic anhydride copolymers and methoxy polyethylene glycol amines and/or polyethylene glycol monoalkyl ethers, or a mixture of styrene-maleic anhydride copolymers and methoxy polyethylene glycol amines and/or polyethylene glycol monoalkyl ethers, or a mixture of styrene-olefins/cyclic olefins-maleic anhydride terpolymers and methoxy polyethylene glycol amines and/or polyethylene glycol monoalkyl ethers. These reactions lead to formation of a kind of carboxylic salt containing polymer, which can be used alone in concrete. Only a small amount of this substance is needed to provide excellent water reduction, high concrete flowability and high early strength. | ||||||

| 70 | Dry application papercrete | US15293921 | 2016-10-14 | US10150705B2 | 2018-12-11 | James R. Brock |
| 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 sands and/or pumice and Portland cement. The resulting dry, granular 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 desired volume such as a form in a dry state and injecting water into the dry papercrete mix until the mix is sufficiently wetted without a requirement for 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. | ||||||

| A dry papercrete mix containing a pulp of fiber material such as newsprint and sharp sand, Portland cement and adding additional sand and/or pumice. The resulting dry, granular mix can then be handled stored and used in the manner which is conventional for concrete.

Basalt reinforcing bars and meshes may be included in shapes cast from the hydrated mix in combination with or substitution for steel reinforcing structures. Including basalt in the mix and in reinforcing systems allows the design of joints between structural modules to provide exceptional strength in a unitary structure so formed. | ||||||
