Disclosed herein are compositions and methods for increasing the viscosity of a calcium-containing fluid by addition of a modifying agent. The resulting enhanced viscosity fluid may be used in a variety of applications including drilling, to create an enhanced-viscosity fluid, and demolition/mining to create an expansive putty for use in underwater and overhead applications.

The invention relates to an unsaturated polyester resin of low molecular weight which is useful for the preparation of engineered stone. When mixing the unsaturated polyester resin with a fine inorganic particulate material such as cristobalite, a formable composition is obtained that can be further processed and cured to finally yield engineered stone as composite material. The invention also relates to a method for the preparation of engineered stone as well as to the use of the unsaturated polyester resin for the preparation of engineered stone.

A process for making a cement, the cement containing a naturally occurring silicate bound in an organic binder, and a metal oxide. An example process includes dissolving the organic binder at least in part, using an effective amount of a chemical activator. An example process also includes providing the silicate to react with other components of the cement. An example process also includes providing the silicate to participate in crystal growth. An example process also includes providing the silicate so that the cement is a structural load bearing cement.
