ABSTRACT:
A cementitious material is formed without the necessity of sand or fresh water by sizing coarse aggregate with silicon dioxide in salt water and mixing the sized aggregate with cement. Fresh water is not required, and the conventional fine aggregate component (typically sand) can be omitted. This material can be formed using a minimal amount of water resulting in a high-strength, light weight, cementitious material comprising a plurality of sized aggregate elements positioned contiguous to one another at a plurality of points and defining spaces in between. The aggregate elements are bonded together at the points of contiguity into a rigid coherent body.
