Abstract: A process for producing a honeycomb structure includes: manufacturing a honeycomb-shaped formed article by kneading a forming raw material containing ceramic as a main component and a forming auxiliary, an additive, and a pore former to prepare kneaded clay and forming and drying the kneaded clay, calcining the honeycomb formed article to obtain a calcined article, and firing the calcined article. Upon performing a tensile load measurement of the kneaded clay or the formed article, a slope θ of the straight line through an inflection point b and an yielding point c of a graph showing a relation between the tensile load and a displacement amount is below 100% of a slope δ of the straight line through a starting point a where an elastic deformation is shown and the inflection point b.

Abstract: A fill material mix that includes coal processing wastes, at least one coal combustion by-product and a neutralizing/stabilizing by-product that may be the same as or different than the coal combustion by-product is mixed with water to form a mortar. The mortar can be placed in abandoned mines and other appropriate underground or surface locations as a fill material that is environmentally more benign that the individual components of the mix. The mortar cures rapidly to provide a surface that can support heavy equipment.

Abstract: High-flexural-strength concrete is produced by mixing wet hydraulic cement-sand mixture with coarse, flat, tabular aggregate, pouring the resulting mixture into a form in a shallow layer, vibrating the form containing the mixture, thereby orienting the coarse aggregate particles, pouring another shallow layer of the mixture into the form, again vibrating the form, and repeating these processes until the form has been filled to the desired level. The mixture then is allowed to cure. Cast-in-place items are prepared by placing thin layers or lifts of oriented, tabular-aggregate concrete into conventional forms and vibrating each lift using flat-plate vibrators.
