A rapid setting, water durable binder composition includes a mixture of: a reactive powder including cement, at about 10-40 wt. % of the reactive powder, -stucco at about 30-75 wt. % of the reactive powder, and pozzolanic material at about 5-30 wt. % of the reactive powder; a plasticizer in an amount equal to about 0.05-3 wt. %, preferably 0.1-3 wt. %, of the reactive powder, and water.

Methods and compositions for cementing are disclosed. Embodiments include a method of cementing comprising: providing a set-delayed cement composition comprising water, pumice, hydrated lime, a primary set retarder, a secondary set retarder; activating the set-delayed cement composition to produce an activated cement composition; introducing the activated cement composition into a subterranean formation; and allowing the activated cement composition to set in the subterranean formation.

This invention relates to manufacturing briquettes, pellets and shapes from recycled asphaltic limestone powder derived from waste residential roofing products. Briquettes and pellets are manufactured through a densification process at varying temperatures, creating recycled asphalt pellets, asphalt limestone pellets and bio mass and coal fines briquettes. Various shapes, including curbs and posts, are manufactured through heat and pressure in molds. Seawalls, walkways and wall panels are manufactured by blending asphaltic limestone powders with polymer resins and extruded or pultruded into shapes.

The present invention is directed to a plaster composition with a reduced carbon footprint and a method of making and using such plaster composition. In one aspect, the plaster composition may include a workability composition and a binder. When hydrated with water, a hydrated plaster composition may have enhanced workability, enhanced surface texture, enhanced finish, and may have a reduced carbon footprint as compared to a traditional plaster composition.
