Geopolymer expansion additive

A geopolymer having an embedded time-release control of chemically reactive, activation components the time-controlled activation of geopolymer foam pastes, mortars, and concretes, comprising:

• (1) at least one dry powdered component;
• (2) at least one alkaline activator component;
• (3) at least one non-reactive aggregate;
• (4) water;
• (5) at least one foaming agent;
• and
• (6) an admixture including at least one aggregate coated with at least one coat of wetting and sticking agent which is in turn coated by at least one reactive coating media, which is in turn coated by at least one non-reactive coating media to create a protective shell around said reactive coating media and provide a controlled time-release delivery of said reactive components, whereby said geopolymer holds an initial wet-batch volume prior to the production of foam and the initial setting of said geopolymer in a dormant period between zero and 20 minutes, and once fully expanded through the production of foam reaches volumes of 1.5 to 4 times the dormant, pre-expanded volume;
• and
• wherein the foam density of a fully cured product made from said composition has a thermal resistance (IP) R rating from 0.5 R per inch to 6 R per inch, can withstand 1200 degrees F. without suffering structural decomposition or releasing toxic gasses.
