Abstract: The invention comprises a method of making lime, dolomitic lime, hydraulic cement such as portland cement clinker and co-products such as pozzolan, acids, alumina, silica and the like while producing reduced amounts of carbon dioxide. The method comprises combining hyaloclastite with a first acid to form a first salt, combining the first salt with a second acid to form a second salt and heating the second salt to form an oxide.
Abstract: A method of making high performance concrete, the method may include adding ground glass powder (GP), nanosilica (nS) powder, cement, silica fume, fly ash, and sand to create a homogenized mixture. The method may also include homogenizing the mixture by mixing and adding water and superplasticizer to the homogenized mixture to obtain a slurry. The method may also include mixing the slurry until a high flowability mixture is obtained. The method may then include adding a first microsteel fiber (T1) to the high flowability mixture; adding a second microsteel fiber (T3) to the high flowability mixture; adding a third microsteel fiber (T4) to the high flowability mixture; and casting the high flowability mixture.

Abstract: Class C fly ash-based cementitious materials, concretes, and related techniques are disclosed. In accordance with some embodiments, an activated class C fly ash-based cementitious material may be produced by intergrinding class C fly ash (e.g., classified to remove quartz and/or other contaminants and, thus, increase the reactive materials present), an activator, sodium citrate, borax, and a polycarboxylate material. The class C fly ash may have an amorphous glass content of about 60 wt % or more, a calcium oxide (CaO2) content of about 20 wt % or more, and a quartz content of about 10 wt % or less. The activator may be a chemical which reacts with class C fly ash to form strätlingite structures therein when introduced with water. In some cases, the cementitious material may be provided as an all-in-one powder blend. In some cases, techniques disclosed herein may be utilized in providing a fast-setting flowable fill material.
