Abstract

Official abstract text for this publication.

A lightweight composite having an activated surface contains a lightweight hollow core particle having cement grains which may be adhered to the hollow core or embedded in the surface of the hollow core. The hollow core particle may be prepared from calcium carbonate and a mixture of clay, such as bentonite, and a glassy inorganic material, such as glass spheres, glass beads, glass bubbles, borosilicate glass and fiberglass.

First claim

Opening claim text (preview).

What is claimed is: 1 . A composite comprising a lightweight hollow core and cement grains, wherein the lightweight hollow core is formed from calcium carbonate, clay and an inorganic material and further wherein the cement grains are adhered to the surface of the lightweight hollow core, embedded in the surface of the lightweight hollow core or are both adhered to the surface of the lightweight hollow core and embedded in the surface of the lightweight hollow core.…
