Portland cement concrete slab-on-ground fabrication method for performance satisfaction and reduced carbon emission

A ground site for a building is prepared for construction of a portland cement concrete slab-on-grade (PCC SoG). Using a computerized weather application, weather conditions for a geographic locale that includes the ground site are monitored to identify a window-of-time during which the weather application indicates there is a less than 50% chance of precipitation at the geographic locale. The surface of the ground site is proof rolled during the window-of-time. Using concrete emplacement equipment during the window-of-time and only after the ground site passes proof rolling, wet concrete is emplaced on the ground site to a nominal thickness that does not exceed 7 inches and that is at least one inch less than a PCC SoG design for the ground site having a design thickness based on design guidelines set forth by the American Concrete Institute. Emplacing must be completed with at least 4 hours remaining in the window-of-time.

Woven geotextile fabrics

Disclosed are exemplary embodiments of woven geotextile fabrics. In exemplary embodiments, a geotextile has a high water flow rate, such as a water flow rate of at least 125 gallons per minute per square foot, etc.

Method for slowing an aircraft using a foamed glass composite runway

A method of slowing an aircraft overrunning a runway, including covering an area adjacent a runway with irregular foamed glass bodies having aspect ratios of about 1:1.9 and diameters of about 10 mm to about 80 mm to define a bed, pouring liquid cement over the foamed glass bodies such that the cement infiltrates at least through the bed, curing the liquid cement to define a composite material of foamed glass bodies in a cementitious matrix, and crushing at least a portion of the composite material with an oncoming aircraft, slowing the aircraft. The composite material is at least 85 volume percent foamed glass bodies. When pouring the cement, the liquid cement flows over and around the foamed glass bodies. The aggregate bodies crush and break up before slip failure occurs when being overrun by an aircraft. The aggregate bodies intersect to define stacking angles of about 35 degrees. The cementitious matrix has a cementitious surface.

Base For Turf System

An underlayment layer is configured to support an artificial turf assembly. The underlayment layer comprises a core with a top side and a bottom side. The top side has a plurality of spaced apart, upwardly oriented projections that define channels suitable for fluid flow along the top side of the core when the underlayment layer is positioned beneath an overlying artificial turf assembly.

VOID FORMING MODULE, METHOD OF PREPARING A STRUCTURE AND USE OF SUCH MODULE IN THE PREPARATION OF A STRUCTURE
20240117570 · 2024-04-11 ·

There is provided a void forming module (100), the module including a support surface (110) including a first generally planar upper region (112), a second generally planar lower region (114), and a third generally convex region (116) joining the first region and the second region. At least one of the first region, the second region, and/or the third region includes at least one aperture (120,122) for the passage of fluid through the void forming module. There is also provided a structure (200) including the void forming module, a method of preparing a structure, and the use of the void forming module.

Road structure reconstructed from large-scale independent underground garage and construction method thereof

A road structure reconstructed from large-scale independent underground garage and a construction method, which solves the problem of a newly constructed urban expressway passing through large underground space. The technical point is a construction method for the road structure reconstructed from large-scale independent underground garage, including the following steps: S100: segmentation for the garage, S200: preparation before construction: the materials and equipment required for construction are transported to the site, and the construction site is cleaned, S300: reconstruction for the front section, S400: reconstruction for the middle section, S500: reconstruction for the rear section. The inventiveness of the present disclosure is the application of segmentation construction, the front section is completely obsoleted, a transition section is provided at the middle, and the design of the rear section adopts a double-deck road, thus the original underground garage structure is fully utilized.

Foamed glass composite arrestor beds having predetermined failure modes

An arrestor bed for slowing an oncoming aircraft, including an elongated excavation, a plurality of foamed glass aggregate bodies positioned within the elongated excavation, and a covering positioned over the elongated excavation to define an arrestor bed. The respective foamed glass aggregate bodies are oblong, irregularly shaped bodies and have characteristic stacking angles of about 35 degrees. The arrestor bed has a rapid brittle crushing failure mode under compression.
