  • Patent number: 11174201
    Abstract: Carbon dioxide and ash are two major waste by-products from coal fire production. Presented herein is are methods, material, and devices for storing carbon using high ash-content building material. The idea is to generate materials with commercial values to offset the cost for carbon capture. Ash with alkali activator (geopolymer) concrete has been studied extensively for its superior performance (higher strength) than ordinary Portland cement (OPC) concrete. However, most geopolymer concrete needs energy input in the forms of pressure and heat, which in turn are usually based on electricity produced through power plants.

  • Patent number: 11168488
    Abstract: The present invention refers to a mechanically activated cementitious composite for stopping the impact of firearms, which involved the designing of mixes of Portland Composite Cement PCC mechanically activated through high energy mechanical milling (HEM) with other ingredients, such as: Ordinary PCC Cement, fine sand, fibers, and polymeric additives, among other compounds, to prepare high-performance composite walls capable of stopping several calibers up to type 50 (typically loaded in Barret rifles). In accordance with Mexican and U.S. Standards for ballistic tests, which entail the approval of the concrete ballistic-resistant wall as long as it resists one impact with a 50 caliber Barret, the present invention allows the construction of composite walls (with dimensions of 40×40×15 cm) with mechanically activated cement and performance complying with the standards.

  • Patent number: 11168029
    Abstract: Mineral fines are used to reduce clinker content in concrete, mortar and other cementitious compositions, typically in combination with one or more pozzolanically active SCMs. Mineral fines can replace and/or augment a portion of hydraulic cement binder and/or fine aggregate. Mineral fines can advantageously replace a portion of cement binder and fine aggregate, acting as an intermediate that fills a particle size void between the largest cement particles and smallest fine aggregate particles. Supplemental lime can advantageously maintain or enhance balance of calcium ions in the mix water and/or pore solution. Supplemental sulfate can advantageously address sulfate deficiencies caused by high clinker reduction, use of water reducers and/or superplasticizers, and SCMs containing aluminates. Such systematic approach to beneficially using mineral fines, SCMs, lime, and sulfate addresses many issues and permits high clinker reduction with similar or increased strength.
