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 composite, time-delayed, polymer-coated, granulated material for maintaining hydration in plants is formulated to delay acceptance of water in order to operate in drilling, plugging, and disking equipment used for aeration, soil amendment, or both. Whether potted or outdoors, whether relying on a third-material binder or a small, hydrated portion of the polymer itself as a binder, the material may be injected or otherwise placed below the surface of soils. Water is eventually absorbed sufficiently to expose the bulk of the hydrating particles attached to each granule. Addition of the granulated material as a soil amendment resists dehydration normally occurring in plants between waterings, yet its initial delay in hydrating supports water-jet injection and soil integration by resisting premature expansion from hydration.
摘要翻译： 制备用于在植物中保持水合的复合时间延迟的聚合物涂覆的造粒材料，以延迟接受水以在用于曝气，土壤修复或两者的钻孔，堵塞和盘磨设备中操作。 无论是盆栽还是户外，无论是依靠第三种材料粘合剂还是将聚合物本身的一小部分水合部分作为粘合剂，该材料可以注入或以其他方式放置在土壤表面之下。 水最终被充分吸收以暴露附着在每个颗粒上的大部分水合颗粒。 添加粒状材料作为土壤改良剂可以防止植物在浇水之间发生脱水，但是其水合作用的初始延迟通过抵抗水合过早膨胀来支持水射流注入和土壤整合。

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.
