Abstract
A construction composition developed to provide a material of construction which can be utilized to build essentially all types of structures, including houses, office buildings, and the like, which composition is capable of being wet mixed and subsequently molded into convenient and useful shapes. The composition has great strength, excellent shrink resistance properties, is highly shock resistant, provides good insulation for structures, and is adapted for use with suitable molds to form the entire wall structure of a house or other building in a single pouring.
