New Zealand Steel approaches solid waste management by following the principles of avoid, reduce, reuse, recycle. If waste generation cannot be avoided, the best way to deal with it is to lessen the amount created and then find positive ways to reuse and recycle any remaining waste. The company refers to solid wastes as "by-products", as ...

Scoria removal will occur in small incremental sections of approximately 10 acres in size, not to exceed 20 acres in any given year, for the purpose of using that scoria on adjacent roads needed for coal mining operations. As the scoria mining moves forward, TBCC will reclaim lands equivalent to the amount of acreage that is being mined.
Scoria is widely available around the central towns of Ethiopia, especially around the rift valley regions where huge construction activities are taking place. The aim …

The application of volcanic scoria, as a green building material, also reduces the environmental damage caused by natural stone [3–8]. Because volcanic scoria has a high porosity, it reduces the risk of explosive concrete shedding produced by pore pressure build-up generated by internal steam when the concrete is heated [9].
Steel-fiber-reinforced scoria aggregate concrete (SFSAC), which contains scoria aggregate and steel fiber, was developed to reduce the environmental impacts and improve the energy efficiency of buildings. Experimental studies were performed. The test variables included steel fiber volume contents (0%, 0.5%, 1.0%, and 1.5%), freeze-thaw …

"Scoria", at least in French, is a very vague term referring to whatever hard particles are left from firing. Here, we also use "Pumice", another "by-product" of volcanism. There's plenty of pozzolan in the …
The strength of lightweight self-compacting concrete generally depends on the concrete mix design, type of lightweight aggregate, and its characteristics. Other factors like water/binder ratio, inclusion of pozzolan, fiber, and nanomaterials have almost similar behaviors that can be observed in conventional concrete.

Trona. Trona is a sodium carbonate compound that is processed into soda ash or bicarbonate of soda, or baking soda, as it is commonly known. Wyoming has the world's largest deposit of trona, supplying about 90% of the nation's soda ash. This mineral is Wyoming's top export and is shipped to markets around the globe.
