Roofing granules comprising agglomerated inorganic material, and building materials, such as shingles, that include such roofing granules. By fabricating roofing granules from agglomerating inorganic material it is possible to tailor the particle size distribution so as to provide optimal shingle surface coverage, thus reducing shingle weight and usage of raw materials. Additionally, the use of agglomeration permits the utilization of by-products from conventional granule production processes.

The present disclosure discloses a self-curing fluid solidified soil composite curing agent and its application, which is composed of the following raw materials by mass percentage: 30-35% of cement, 10-20% of slag, 10-20% of gypsum, 5-8% of calcium carbide slag, 30-39% of microbial curing agent, 1-5% of self-curing microbeads. The present disclosure can effectively improve the compressive strength of the fluid solidified soil while ensuring the early fluidity of the fluid solidified soil, inhibit the shrinkage deformation of the fluid solidified soil, and improve the durability of the fluid solidified soil. The present disclosure improves the recycling rate of solid waste resources and has the characteristics of low cost and remarkable environmental protection effect under the premise of ensuring the application effect, which is suitable for large-scale promotion and application.

A gypsum wallboard having a core with a central core layer and one or more densified layers is disclosed. At least one densified layer contains salt absorbent particles of zeolite and/or hydrotalcite to improve adhesion of the gypsum core to a cover sheet. Also, methods of making the gypsum wallboard and a wall system for employing the gypsum wallboard are disclosed.

Beneficial use structures are disclosed that include coal combustion residuals (CCR) mixed with water and a binder to form a structural material, and adapted to be compacted for use in the formation of the beneficial use structure. Various structures having beneficial uses are described, including compressed air storage facilities and a pumped hydroelectric facility, including such a facility adapted for use with a lock system of a waterway.

A process for manufacturing pellets includes providing a first supply of a first material and a second supply of a binder including a second material in respective storage units. The first supply of the first material is mixed in a counter-current mixer with the second supply of the binder and water to produce a plurality of pellets. The mixing occurs simultaneously with pelletizing in the mixer. The plurality of pellets are discharged from the mixer.
