1. A manufacturing process for forming a cemented siliceous solid, comprising, in a continuous process:

subjecting precursor-containing solids to dissolution under acoustic perturbation in a sonoreactor to yield an initial slurry including dissolved precursors;

feeding the initial slurry into a flow reactor for hydrothermal synthesis and subjecting the initial slurry to hydrothermal synthesis to yield a subsequent slurry including siliceous solids formed from the dissolved precursors, wherein the initial slurry is subjected to hydrothermal synthesis for about 10 seconds to about 1000 seconds; and

feeding the subsequent slurry into a cementation reactor and subjecting the subsequent slurry to cementation to yield a cemented siliceous solid.
