A quick-setting concrete mixture that uses calcium sulfoaluminate as a binder cement. In one embodiment, the disclosed concrete mixture may be prepared using a revolutionary drum mixer truck and may recycle surplus or leftover concrete. In one embodiment, the mixture may use air entrainment; such as liquid air entrainment or foam generated air entrainment, to manufacture the concrete mixture.

The invention is the development of new and unique formulations and mixtures along with unique and improved manufacturing processes for a clear departure for all manufacturing processes in which cement-based formulations and mixtures are commonly utilized in manufacturing SIPS of the prior art and or the teachings of the poured/casted/formed cement based formulations/mixtures and manufacturing processes of the prior art of building/construction industry. The invention serves the current building/construction industry with new and unique formulations and mixtures along with unique and improved manufacturing processes that produce SIPS with enhanced performance characteristics which are unparalleled teachings not present, nor found in any of the prior art.

Disclosed are asphalt binder compositions and methods for making such compositions with pure sterol:crude sterol blends. The sterol blends improve various rheological properties.

A cementitious material made from industry accepted precursor materials that will adhere to existing concrete or rock has several exploitable features beyond adhesion. The primary motivation for the invention was a self-adhering thin overlay of quality better or equal to the parent concrete floors is now possible. Structural repair of concrete is possible. There are a range of compositions and exploitable features than can be used to give the product flexibility across many concrete repair applications. This resulting material can demonstrate the low permeability and high strength closer to natural stone materials such as quartz and dolomite rocks than to concrete but intermediate compositions are technically viable as well. The material can be used for high quality precasts.
