    Abstract: Disclosed is a process for exfoliating a layered material to produce nano-scaled platelets having a thickness smaller than 100 nm, typically smaller than 10 nm, and often between 0.34 nm and 1.02 nm. The process comprises: (a) charging a layered material to an intercalation chamber comprising a gaseous environment at a first temperature and a first pressure sufficient to cause gas species to penetrate into the interstitial space between layers of the layered material, forming a gas-intercalated layered material; and (b) operating a discharge valve to rapidly eject the gas-intercalated layered material through a nozzle into an exfoliation zone at a second pressure and a second temperature, allowing gas species residing in the interstitial space to exfoliate the layered material to produce the platelets. The gaseous environment preferably contains only environmentally benign gases that are reactive (e.g., oxygen) or non-reactive (e.g., noble gases) with the layered material. The process can additionally include dispersing the platelets in a matrix material to form a nanocomposite. The process also can include an additional process of re-compressing the nana-scaled platelets into a product such as a flexible graphite sheet.

    Abstract: A cement mix which is suitable for cementing in subterranean formations to provide zonal isolation or for blocking or plugging an abandoned pipeline or back filling a mine shaft, tunnel or excavation contains Portland cement or a mixture of two components selected from Portland cement, fly ash, slag, silica fume, gypsum, limestone and bentonite; and diatomaceous earth, preferably having a BET nitrogen adsorption specific surface area between from about 30 to about 100 m2/g. The cement mix may further contain an alkali metasilicate and/or alkali silicate, zeolite and/or aluminum silicate, an accelerator, such as an inorganic salt, and/or an alkaline metal oxide, as well as a lightweight density modifying agent, including glass, ceramic or plastic spheres. A cementitious slurry, formulated from the cement mix, has a density less than or equal to 1500 kg/m3 and exhibits good compressive strength.

    Abstract: The present invention relates to concrete, mortar and other hardenable mixtures comprising cement and fly ash for use in construction. The invention includes a method for predicting the compressive strength of such a hardenable mixture, which is very important for planning a project. The invention also relates to hardenable mixtures comprising cement and fly ash which can achieve greater compressive strength than hardenable mixtures containing only concrete over the time period relevant for construction. In a specific embodiment, a formula is provided that accurately predicts compressive strength of concrete containing fly ash out to 180 days. In other specific examples, concrete and mortar containing about 15% to 25% fly ash as a replacement for cement, which are capable of meeting design specification required for building and highway construction, are provided. Such materials can thus significantly reduce construction costs.
