Abstract
A method of using a flowable binder for construction or repair comprises providing a binder mixture including an alkali metal silicate, fly ash, slag, and added water, where a total water-to-solids mass ratio of the binder mixture is in a range from about 0.2 to 0.5. The binder mixture is mixed together with inert particles to form a flowable mortar. The flowable mortar is distributed over a bed of coarse aggregate, and the mortar seeps into interstices of the coarse aggregate. Upon curing, a composite comprising reinforcement material embedded in a cured binder is formed.
