The invention relates to flexible geo-composites and a method for their production. Such geo-composites are multilayer geotextiles with a cementitious material. The multilayer comprises a non-woven fibrous top layer (16), a base layer (10) and a core layer (12) of cementitious material including cement between the top layer (16) and the base layer (10). A plurality of fibers of the top layer (16) penetrates the core layer (12) and is arranged on the base layer (10). The multilayer is flexible, configured to be curved in at least one direction and preferably in two directions, becomes rigid upon absorbing water. The cementitious material includes cellulose fibers, whose weight is at least 0.3% and does not exceed 5% of the weight of the cement of the cementitious material. Further, the core layer (12) of the multilayer may include solid admixtures and/or glycol-oil mixtures.

The present invention relates generally to wall repair compounds such as joint compounds, spackling compounds, and the like used to repair imperfections in walls or fill joints between adjacent wallboard panels. Particularly, the present invention relates to such a wall repair compound comprising a dust reducing additive that reduces the quantity of airborne dust generated when the hardened compound is sanded. The dust reducing additive also imparts adhesion to the wall repair compounds to which it is added, for example to a joint compound. The dust reducing additive comprises microcrystalline-wax based emulsion.

The present invention relates to a reed composite material to be used as a construction material, to a method for producing a reed composite material, and to a construction material using same. In detail, the reed composite material comprises 55 to 75 wt % of reed stems, the nodes of which are removed, and which has a particle size of 40 to 180 mesh when ground; and 25 to 45 wt % of a thermoplastic polymer, wherein the thermoplastic polymer is impregnated into the fibers of the reed stem, thus obtaining an environmentally-friendly and high-strength composite material in which a swelling phenomenon is prevented. In addition, reeds used as a raw material of the composite material of the present invention have a natural texture and pattern similar to those of natural wood, and have a weight or specific gravity that is higher than that of cornstalks, bagasse, or rice straw, which are non-wood materials, and therefore are significantly advantageous as an interior or exterior material. Further, the composite material of the present invention can be used as various construction materials such as an interior material, an exterior material, a landscape architecture material, and the like.

Disclosed are a mortar for concrete mainly consisting of urethane foam and a method for manufacturing the same, in which urethane foam and Styrofoam used as insulating materials for household electronic appliances and a pre-cast panel are not discarded, but recycled such that the urethane foam and the Styrofoam are mixed with concrete in the construction of flooring of apartments or an ondol of houses. Low weight structure, superior sound-absorption effect and heat insulation effect can be obtained, and cracks are prevented from being generated in the constructed part. Construction work is simplified, and economical efficiency is enhanced. Collected waste urethane foam and waste Styrofoam are pulverized into a size of 1 to 10mm using a pulverizer. The pulverized urethane foam and Styrofoam are mixed to each other to form urethane foam. Admixture is added to the urethane foam, and then cement and water are mixed with the urethane foam in a predetermined ratio to form a lightweight insulating urethane foam concrete mortar using a mixer and a truck mixture. The lightweight insulating urethane foam concrete mortar is manufactured and is transported from a mixing area to a construction part such that materials of the concrete is prevented from being separated from each other. The concrete is poured using squeezing equipment and hydraulic transfer equipment and then cured for a predetermined curing time to prevent sudden change in the temperature.
