摘要： A method of reducing the swell potential of an expansive clayey soil comprising expansive clay mineral(s) at a proportion of the total weight of the expansive clayey soil (PECM). The method includes (a) calculating a first amount of a swelling reduction agent to be incorporated into the expansive clayey soil to form a first swelling reduction agent incorporated expansive clayey soil with a reduced swell potential no greater than a pre-set level T with a nano-level constitutive modeling based on the water content and the CEC of the expansive clayey soil and PECM. The swelling reduction agent is at least one selected from calcite, gypsum, potassium chloride, a composition comprising exchangeable K+, a composition comprising exchangeable Ca2+, and/or a composition comprising exchangeable Mg2+, and (b) incorporating the first amount of the swelling reduction agent into the expansive clayey soil to form the first swelling reduction agent incorporated expansive clayey soil.

摘要： There is a process for creating graphite free non-fired refractory products, which are molded using presses and which includes using a plurality of different binders. The binders comprise a first binder for binding grains of granulation between room temperature and 400° C., a second binder binding the grains of granulation between 300 and 900° C.; and a third binder binding granulations of the refractory materials that enter into ceramic binding at temperatures above 900° C. This process is for producing at least one of magnesia chromite bricks, magnesia spinel and spinel bricks, magnesia zirconia and magnesia zircon bricks, magnesia hercynite and magnesia galaxite bricks, dolomite, dolomite-magnesia, and lime bricks, forsterite and olivine bricks, magnesia forsterite bricks, magnesia pleonast bricks, magnesia bricks. These products are configured to operate as a fire-side, refractory lining of large-volume industrial furnaces operated with an essentially oxidizing atmosphere, for the production of cement, lime, magnesia, and doloma.

摘要： Drying of moist material, e.g., rubber crumbs, is effected using a screw machine which disperses the particles in an air stream. The air stream and particles pass through a conveying pipe, in which further drying occurs, and then into a separator from which the dried particles fall onto a conveyor. The conveying pipe and the separator are cooled. The cooling prevents accumulation of the particles on the walls of the equipment.
