摘要： A concrete composition and method include a portion of fine aggregate bearing a coating of a polymer or an admixture, which may be a continuous coating layer or a layer of powdered, discrete particles embedded in a binder. The polymeric coating may be an admixture in powdered form, a super absorbent polymer (insoluble in water, but absorbing water), or another polymer such as the acrylamides, co-polymers thereof, polyacrylamides, or the like (soluble in water). The coating absorbs water, but particles are too small to form significant voids. Water is absorbed into the concrete mix in far greater proportions (e.g. w/c ratio over 0.5) improving workability, doubling workability time, and improving ultimate compressive stress (strength).

摘要： A method for improving the performance of fracturing processes in oil production fields may rely on polymer coated particles carried in the fracturing fluid. The particles may include heavy substrates, such as sand, ceramic sand, or the like coated with polymers selected to absorb water, increasing the area and volume to travel more readily with the flow of fluid without settling out, or allowing the substrate to settle out. Ultimately, the substrate may become lodged in the fissures formed by the pressure or hydraulic fracturing, resulting in propping open of the fissures for improved productivity.

摘要： A material for optimizing and maintaining at least one of water, nutrients, biocides, and other protectant or growth supporting chemicals in natural soils by decreasing leaching, evaporation, and volatility through application of agglomerated granules (prills) formed of engineered hydrating particles, a binder, nutrients, and protectants to the soil. Typical application is by applying prills simultaneously with seeds when drilled, broadcast, or otherwise distributed.

摘要： A method for improving the performance of hydraulic fracturing processes in oil production fields wherein modifiable coated proppants used in the fracturing fluid are produced on a well-site. Various types of coated proppants may be produced based on real-time, down-hole information obtained and utilized at the well-site.
