A geopolymer formulation is suitable for making a functional geopolymer when combined with an aggregate and water. The geopolymer formulation includes a precursor including an oxide and an activator. The geopolymer formulation is a dry solid powder with a particle size in the range of 45 to 60 microns.

Brine sludge is an industrial waste generated in chloral alkali industry. The generated brine sludge waste is dumped into landfills and contains barium sulphate, calcium carbonate, magnesium hydroxide, sodium chloride, clay, and toxic elements like chromium, zinc, copper, and vanadium, therefore posing an environmental threat. Consequently, there is an urgent need to convert toxic brine sludge waste into its non-toxic form. The present invention thus aims to achieve total utilization of this brine sludge for making functionalized brine sludge material useful for a broad application spectrum.

A system and associated method constructs a building material from lunar soil. A magnetic sorter magnetically sorts the lunar soil and the system creates a layered surface comprising a microwave susceptible, thermal conductive top layer of lunar soil and a poorly microwave-susceptible and poorly thermally conductive sublayer of lunar soil. A microwave generator generates microwave energy into an antenna and directs the microwave energy onto the top layer of lunar soil to sinter the microwave susceptible, thermal conductive top layer of lunar soil.

A method for recycling concrete waste from construction and/or deconstruction, including at least one step of microwave processing of concrete blocks, at least one step of mechanical processing, and at least one step of carbonation of recycled concrete aggregates and/or recycled concrete fines; and a recycling installation for carrying out the recycling method and to recycled concrete aggregates obtained by the steps of microwave processing of concrete blocks and mechanical processing.
