A cement composition can include water and a blended cement. The cement composition can be free of Portland cement. The blended cement can include cement and a supplementary cementitious material. The cement can be calcium aluminate cement or calcium aluminophosphate cement. Fly ash is a common supplementary cementitious material containing silica. However, fly ash can have large variances depending on the source of the fly ash. Instead of fly ash, the supplementary cementitious material can be ground synthetic glass, such as soda-lime glass, which has consistent properties regardless of the source.

A composition configured to be mixed with cement, and associated systems and methods are disclosed herein. In some embodiments, the composition includes at least 10% by weight lime particles, and at least 35% by weight pozzolan particles. Properties of the composition can include a magnesium oxide concentration of at least 0.5%, and an iron oxide concentration of at least 0.5-2.0%, an aluminum oxide concentration of 2-8%, a silicon dioxide concentration of 20-40%, a potassium oxide concentration of 20,000-30,000 ppm, and a sodium oxide concentration of 10,000-20,000 ppm. In some embodiments, the lime-based cement extender composition, or product, is combined with cement to produce a cement blend for use in the mining industry as mine backfill.

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.

The present disclosure relates generally to plaster wall panels, for example, suitable for covering interior wall frames. The present disclosure relates more particularly to a plaster wall panel including a first plaster layer, a second plaster layer, and a damping layer disposed between the first and second plaster layers. The first plaster layer has a first thickness and is composed of a first plaster material that has a first material property. The second plaster layer has a second thickness and is composed of a second plaster material that has a second material property. The first thickness is smaller than the second thickness, and the first and second material properties are different.
