A porous ceramic structure has a porosity of 20% to 99%, and includes one principal surface and another principal surface opposite to the one principal surface. At least one cut is formed from the one principal surface toward the other principal surface. An aspect ratio of a divided portion divided by the cut is greater than or equal to 3.

A method of making a composition material comparable to strength with regular concrete but with a lower weight and thermal conductivity is provided. The process includes forming a first composition from a foam admixture of a first cementitious slurry and foam. This first composition is set and then pulverized to a fine dust. The fine dust is then added to a second cementitious slurry, producing a lightweight and insulative composition material for construction applications.

A ceramic precursor mixtures for extrusion and firing into porous ceramics. The ceramic precursor mixtures include ceramic beads and green inorganic shear binder agglomerates. The green inorganic shear binder agglomerates can include inorganic filler particles and a polymeric binder. The green inorganic shear binder agglomerates can deform under an applied shear stress during mixing and/or extrusion such that they are smeared into a plurality of interbead gaps between adjacent ceramic beads or pore former particles. During firing, the smeared green inorganic shear binder agglomerates can sinter and react to form ribbons extending between, and interconnecting adjacent ceramic beads.

A composition, utility material, and method of making a utility material is disclosed. A composition having an improved setting time may include a plurality of microparticles mixed with a sodium silicate binder and an isocyanate setting agent, where the microparticle composition has a setting time of less than or equal to one hour. A utility material may be a wallboard that includes the composition.
