Compositions and methods of forming compositions for a controlled low strength material (CLSM) comprising heavy oil fuel ash (HOFA) and recycled concrete powder (RCP) waste with natural and recycled aggregates and water are provided. In some embodiments, small quantities of Portland cement are also utilized. The recycled concrete powder contains primarily calcite and quartz. The CLSM can be used as a flowable compacted fill in structural and non-structural construction applications.

Disclosed is a composition for a Controlled Low Strength Material (CLSM) including cementitious materials, water, and fine aggregate. The cementitious materials include powdered basaltic lava and Ordinary Portland Cement (OPC). In the composition, the basaltic lava replaces some of the ordinary Portland cement in the CLSM as compared to a conventional CLSM. The basaltic lava replaces 25% to 90% of the OPC in a conventional CLSM. The CLSM can be used as a compacted fill for structural and non-structural construction applications.

A system and method for storing molten sulfur includes a reinforced concrete vessel, the reinforced concrete vessel being subterranean. The vessel has a floor that is a raft footing formed of reinforced concrete and has a floor interior surface. The vessel also has a ceiling that is a slab of reinforced concrete and has a ceiling interior surface. Sidewalls of the vessel extend between the floor and the ceiling and are formed of reinforced concrete, each sidewall having a sidewall interior surface. A liner is bonded to the floor interior surface, the ceiling interior surface, and each sidewall interior surface. The liner formed of an epoxy vinyl ester resin, and a glass fiber sheet embedded in the epoxy vinyl ester resin.

A green concrete and mortar compositions free of Portland cement are disclosed. The compositions comprise Natural pozzolan, nanosilica particles, and alkaline activator. The green concrete produced from the composition of the invention is cured at ambient temperature and has higher compressive strength than that of concrete made with Portland cement.
