A drying-type joint compound can comprise: (a) a primary filler at about 50 weight percent (wt %) to about 98 wt % on a dry basis, wherein the primary filler includes one member selected from the group of calcium carbonate, calcium sulfate dihydrate, and talc, and a mixture thereof; (b) a secondary filler at up to about 25 wt % on a dry basis; (c) a binder at about 1 wt % to about 15 wt % on a dry basis; (d) a polymer thickener at about 0.05 wt % to about 3 wt % on a dry basis; (e) a vesicle dedusting agent at about 0.01 wt % to about 10 wt % on a dry basis, wherein the vesicle dedusting agent comprises vesicles; and (f) an additive up to about 10 wt % o on a dry basis; and (g) water at a ratio of water to dry components of about 1:6 to about 3:1.

The present invention relates to a reinforcement fiber (100) for strengthening a mortar. The reinforcement fiber (100) comprises: a cylindrical fiber body (10); and multiple linear grooves (20) formed on an outer surface of the fiber body (10), wherein the multiple linear grooves (20) comprise: multiple straight linear grooves (30) formed along the longitudinal direction on a surface of the fiber body (10); and an annular linear groove (40) surrounding the fiber body (10) while intersecting the multiple straight linear grooves (30), the straight linear grooves (30) are radially formed with reference to the center of the fiber body (10), and the straight linear grooves (30) and the annular linear groove (40) have a plurality of micro linear grooves (310) formed therein.

Method of forming a concrete slab to reduce or eliminate control joints includes preparing a substantially flat base, overlaying one or more barriers on top of the base, placing a concrete mixture on top of the barrier(s) and base to form a concrete slab, and allowing the concrete to cure without forming control joints. The base is prepared with a flatness of about inch over 10 feet. A side edge is prepared along a periphery of the concrete slab by extending a vapor barrier from a bottom surface of the slab up the side edge toward a top surface of the slab and covering the side edge. A plurality of post-tensioning cables are positioned to extend through the slab and configured to compress and assist in controlling accelerated displacement of the concrete slab during curing and shrinkage. The concrete slab is formed of an evenly gradated and low slump concrete having high fiber content, minimized cement content, and maximized size of large aggregate.

A composite material and process for forming composite material. The composite material comprises a quantity of plastinated plant distributed within a matrix material. The process comprises separating a plant material into plant fibers plastinating the plant fibers and combining the plastinated plant fibers with a matrix material. The plant fibers may be selected form the group consisting of bamboo, hemp and flax. The plant fibers may be formed by crushing a portion of a plant. The matrix material may comprise Polyethylene Terephthalate (PET). The PET may be shredded and heated. The heated composite material may be formed into rebar and be arranged in a pattern within a concrete slurry.
