6 results about "Concrete masonry unit" patented technology

A vegetal concrete masonry unit and method and system for manufacturing thereof are disclosed. The masonry unit comprises treated crop residues (e.g., paddy straw, wheat straw, bagasse), a binder of hydrated lime, ground granulated blast furnace slag (GGBFS), and low-content alkali activator (2.5-20% by mass), and aggregates in a mass ratio of 1:0.1:1.5 to 1:5:5, achieving compressive strengths of 2-20 MPa and densities of 950-1900 kg / m3. The method involves alkali-treating residues at 0.1-10M NaOH for 15-1500 minutes, passing through a screw press, mixing with binder and aggregates to form C-A-S-H and N-A-S-H gels, and high-pressure molding (2-10 MPa). The system includes silos, a retention tank / screw press, pan mixer, and hydraulic press. This sustainable bio-composite utilizes agricultural / industrial wastes, reduces emissions by 80%, is energy efficient, enhances compatibility and mechanical performance, and provides thermal insulation for eco-friendly building blocks and panels.

A wood or manufactured wood-composite based siding used on concrete wall or concrete masonry unit (CMU, or block) construction (including, but not limited to, insulated concrete form construction) with an integrated rainscreen feature. The rainscreen feature or component is applied to, or integrated into or with, the back of the siding (i.e., the inner surface) during the manufacturing process, or in a secondary process thereafter. The features may include raised elements, strips, ridges, or wedges, with one or more channels or spaces. No job-site assembly is required, thereby reducing time and cost.

A concrete masonry unit, comprising a solid portion comprising cement, coarse aggregate, fine aggregate, and 10 percent to 25 percent of microbeads with respect to a total volume of the solid portion; and at least one hollow portion boring through the solid portion; and wherein the concrete masonry unit meets the requirements under standards ASTM C90 as measured according to ASTM C140.

The present invention relates to devices for cutting tile and scoring concrete masonry units. These devices may function without generating large amounts of dust, while still allowing high-throughput cutting and scoring. The present invention features devices for cutting tile that may allow for multiple tiles to be cut simultaneously, thus boosting efficiency. The present invention features devices for scoring concrete masonry units that may enable precision scoring of multiple faces of the CMU. After the CMU is scored by the device of the present invention, it may be easily split along the scoring plane by hitting the top of the CMU with a hammer.

A vegetal concrete masonry unit is provided which comprises cooked crop residues, binder and pulverized fuel ash in a mass ratio of 1:1:1.5 to 1:1.5:3.

A mortarless interlocking concrete masonry unit system includes concrete blocks comprising field blocks, corner blocks, end blocks, and intersecting blocks. Each block includes an interlocking geometry with protruding portions and recess portions configured to engage with adjacent blocks through approximately fifty percent overlap connections. The interlocking geometry enables mechanical bonding in longitudinal, lateral, vertical, and transverse orientations without requiring mortar joints. The system creates structural assemblies through self-aligning connections that resist shear forces while eliminating the need for skilled masonry labor. Central cavities in each block accommodate utility installations and reinforcement materials. The corner blocks provide ninety-degree connections, end blocks enable wall terminations with finished surfaces, and intersecting blocks enable perpendicular wall additions at any location. The lightweight concrete blocks are approximately fifty percent lighter than conventional masonry units while maintaining equivalent structural performance for walls, partitions, foundations, and load-bearing structures.
