Hollow composite powder concrete cover plate

Abstract

The invention relates to a hollow structured composite powder concrete cover plate. The composite powder concrete cover plate is prepared by the following raw materials by mass: 510-600 parts of low-alkaline portland cement or ordinary portland cement, 90-120 parts of silica fume, 130-170 parts of I grade fly ash, 150-185 parts of mineral powder higher than S95 grade with average particle sizes of 10-30 [mu]m, 1,150-1,210 parts of river sand with average particle sizes of 0.16-4.75 mm, 20-24 parts of a high-efficiency compound water-reducing agent, 7-12 parts of a corrosion inhibitor, 25-30 parts of a water-soluble epoxy resin, 130-142 parts of water, 70-80 parts of copper-coated ultrafine steel fibers with diameters of 0.18-0.25 mm and lengths of 10-15 mm, 20-30 parts of end hook steel fibers with diameters of 0.4-0.6 mm, lengths 20-25 mm and tensile strength higher than or equal to 1,000 MPa and 0.8-1.5 parts of polypropylene fibers.

AI Technical Summary

Benefits of technology

This patented technology relates to improved strength and durableness for building components such as cables or pipes. By adding specialized reinforcement elements (fiberglass), these compositions can improve their ability to resist damage caused during construction operations without losing effectiveness over time due to environmental concerns associated therewith. Additionally, this new method allows for more flexible and tougher designs while reducing manufacturing expenses compared to traditional methods like casting plaster moldings. Overall, it provides technical benefits to create stronger yet lighter structures suitable for various applications where high levels of safety standards require them.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving powder concrete' properties such as compressive stress capacity (CS), tensile strength, harden time, water absorption rate, perpendicular force response behavior, weatherproof ability, electrical conductivity, thermal insulation, etc., while also reducing its size without compromising safety or usable lifetime. Existing covers made from common cement suffer issues like being too bulky for applications that require lightweight but strong components due to low bending rigidity and lack of sufficient protection against rust. Additionally, existing covers may lose effectiveness over longer periods when exposed to harsh environments where they could become damaged quickly during construction work hours.
