Abstract: The present invention provides a method and system for manufacturing cement wherein ground particles of cement and calcium sulfate are subjected to infrared sensors, laser sensors, or both, so that emanated, irradiated, transmitted, and/or absorbed energy having wavelengths principally within the range of 700 nanometers to 1 millimeter can be monitored and compared to stored data previously obtained from ground cement and sulfate particles and preferably correlated with stored strength, calorimetric, or other data values, such that adjustments can be made to the mill processing conditions, such as the form or amounts of calcium sulfate (e.g., gypsum, plaster, anhydride), or cement additive levels. The strength and other properties of cement can be thus adjusted, and its quality can be more uniform.

Abstract: The present invention provides exemplary method and additive for making cementitious binders that comprise primarily ground granulated blast furnace slag (GGBFS) having excellent strength at 24 hours, with preferably little or minimal amounts of Ordinary Portland Cement (OPC). As OPC manufacture involves carbon dioxide release into the atmosphere, the use of a GGBFS-based binder composition will help to enhance sustainability practices in the construction industry and minimizing strength losses implied by deletion of OPC. Strength in the GGBFS binder composition is enhanced by an alkaline-earth activator in combination with a strength enhancing component comprising dispersant and secondary activator.

Abstract: Disclosed herein is a reactive cold-applied thermoplastic bond coat system and method of application thereof. The system is a two- or three-component system defined by acrylate-based component(s) and an initiator suspension. Upon mixing of the components at the jobsite, the mixture is applied onto a substrate (e.g., waterproofing membrane), and a pavement material (e.g., asphalt) is applied onto the bond coat. Excellent asphalt compaction was observed, resulting in high surface contact area, along with very low water penetration to the bond coat interface. The high surface contact area and penetration of the asphalt into the bond coat provides a good bond between the asphalt and substrate.

Abstract: The present invention provides a panel sheathing for making wall and roof structures in which the panels (e.g., wood boards, oriented strand boards, plywood, etc.) are pre-coated at a factory, before installation at the building/construction site, using a polymeric barrier coating having specific water permeability, self-sealing properties with respect to penetrated metal fasteners (e.g., nails) in accordance with ASTM D7349 (modified using 1.5-5.0 inches water depth in hydrostatic head testing over sample of coated panel in which a steel nail is driven to within ⅛ inches of being flush with the panel and conditioning the test specimen for 24 hours at 23° C. prior to hydrostatic loading), as well as anti-blocking properties whereby the coated panels can be transported in stacked configuration without sticking or disintegration of the polymeric barrier coating. The coated panels do not require the use at the installation site of felt paper, house wrap, or additional applied barrier coating to provide excellent weather barrier properties. The present invention also provides methods for constructing the panel sheathing structure as well as for making the coated panels.

Abstract: Disclosed are exemplary method and system for manufacturing cement in a vertical roller mill (VRM) using humidity sensor readings. This enables adjustment of operational variables such as material feed, water, grinding additives, air flow, temperature, and their combinations. Exemplary embodiments allow manufacturers to predict and to improve cement properties, such as strength and setting time, by monitoring and managing humidity of air in the VRM and/or its air flow system.

Abstract: Disclosed are methods, compositions, and composition packages for spray-coating a membrane for waterproofing a concrete tunnel applications. After primer coating is applied onto a surface in the tunnel, the coating composition is sprayed to form a membrane, and then concrete is cast or sprayed against the membrane so that it can bond to the membrane. Coating compositions comprise two or more acrylate monomers, as well as initiator, accelerator, and optional additive. Preferably, the coating composition is established by using a two-part package, one part having initiator, the other part having accelerator, and each part containing the monomers and optional additives so that the two parts can be shipped to the application site and mixed in a 1:1 ratio during spraying. The waterproofing coating composition provides excellent bonding with concrete.
