Clean version of the Abstract A production method of ready injection material aims at developing natural hydraulic lime at nano-size by using a single raw material. The production method includes: selecting marl, comprising at least 70% CaCO.sub.3, as the raw material, grinding the marl to have particle size lower than 400 lam, calcining the marl at a temperature between 1000-1200 C., re-grinding the marl after the calcination process, reducing a d.sub.90 particle size of calcined marl to between 200-700 nm after the grinding process, applying a dry mixing process to the material having a reduced particle size, adding water to the material after dry mixing and applying mechanical mixing process during duration between 3-6 minutes at a revolution between 800-1000 rpm, adding super-fluidizing chemical additive to the obtained material, and mixing the material for duration between 3-6 minutes by using ultrasonic homogenizer and mechanic mixing.

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.

A low-carbon cement clinker, having the following parameter ranges: alkalinity coefficient C: 1.0?C?1.5; aluminum-sulfur ratio P: P<1.92; aluminum-silicon ratio N: N<1; and limestone saturation coefficient Cs: 0.9?Cs<1.0. The specific range of each parameter value ensures an idea ratio of mineral composition in the low-carbon cement clinker. The ratio promotes a coordinated interaction among different minerals and compounds present when exposed to water, leading to improved strength development and overall performance of the final cement product.

The present invention relates, inter alia, to method of assessing the reactivity of a polymerizable material (especially an aluminosilicate) in forming a geopolymer. The present invention also relates to methods of forming a geopolymer, and to geopolymers formed by the method. The method of assessing the reactivity of the polymerizable material may include first assessing whether the polymerizable material is layered or particulate. Next, if the polymerizable material is layered, the method may include measuring the moles of polymerization network forming elements in an amount of polymerizable material, whereby the moles of polymerization network forming elements is indicative of the reactivity of the polymerizable material in forming a geopolymer. Alternatively, if the polymerizable material is particulate, the method may include measuring the molar charge of polymerization network modifiers in an amount of polymerizable material, whereby the molar charge of polymerization network modifiers is indicative of the reactivity of the polymerizable material in forming a geopolymer.
