Inorganic polymer compositions and methods for their preparation are described herein. The compositions include the reaction product of a reactive powder, an activator, and optionally a retardant. The reactive powder includes fly ash, calcium sulfoaluminate cement, and less than 10% by weight portland cement. In some examples, the composition is substantially free from alkanolamines. In some examples, the ratio of water to reactive powder is from 0.06:1 to less than 0.2:1. Also described herein are building materials including the compositions.

Calcium sulfoaluminate cement-containing inorganic polymer compositions and methods of making same

Inorganic polymer compositions and methods for their preparation are described herein. The compositions include the reaction product of a reactive powder, an activator, and optionally a retardant in the presence of water and an aerating agent. The reactive powder includes 85% or greater fly ash. The aerating agent can be a blowing agent, a foaming agent, or a mixture of these. Also described herein are building materials including the compositions.
