A kind of ultra-high-strength concrete and thin-walled electric pole made of the ultra-high-strength concrete

Abstract

The invention discloses an ultra-high-strength concrete and a thin-walled electric pole made of the ultra-high-strength concrete. The ultra-high-strength concrete is recorded in parts by mass. The raw materials include: 1000-1200 parts of cement, 180-250 parts of water, silicon 180-200 parts of ash, 1200-1700 parts of quartz sand, 15-20 parts of water reducing agent, 210-240 parts of reinforcing fiber, a thin-walled pole made of the above-mentioned ultra-high-strength concrete, and the thin-walled pole is a hollow structure , made by centrifugal molding process. In the present invention, silica fume, quartz sand, water reducer and reinforcing fiber are added to the cement, and an appropriate mix ratio is adopted to prepare ultra-high-strength concrete whose strength grade can reach C120-C150, and steel fiber and carbon fiber are used as reinforcing fibers, and Grafting polyacrylic acid on the surface of carbon fiber improves the dispersion of carbon fiber. The ultra-high-strength concrete has high compressive strength, strong deformation resistance, high density, and low porosity. The thin-walled pole made of this ultra-high-strength concrete is used in Under the condition of ensuring the forming quality and rigidity of the pole, the wall thickness can be greatly reduced, which is convenient for transportation.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an ultra-high-strength concrete and a thin-walled pole made of the ultra-high-strength concrete. Background technique [0002] Electric poles are one of the most important infrastructures in daily life. Traditional electric poles are mostly ordinary cement electric poles with a small amount of steel skeleton. The notification number CN207999115U includes a rod body, which is composed of a steel frame, a concrete layer, a foamed cement layer, and an anti-corrosion layer. The steel frame is arranged in the middle of the concrete layer. On the inner side of the concrete layer, the anti-corrosion layer is arranged on the outer side of the concrete layer, a lightning rod is arranged on the top of the rod body, a cross arm is arranged on the upper end of the rod body, and a card slot is arranged in the middle of the rod body. [0003] But this kind of ordinary cement pole has low str...

Problems solved by technology

[0004] The first purpose of the present invention is to provide a super-high-strength concrete that overcomes the low strength and poor crack resistance of the concrete used in the prior art to make electric poles, resulting in easy cracking and damage of electric poles. Greatly improved strength, crack resistance and durability

[0005] The second purpose of the present invention is to overcome the problem that the electric poles made of ordinary concrete in the prior art are generally thicker in order to ensure the bearing capacity, heavy in weight, inconvenient for transportation, installation and maintenance, poor in durability, and short in service time The problem is to provide a thin-walled electric pole made of the above-mentioned ultra-high-strength concrete, which can greatly reduce the wall thickness of the electric pole under the condition of ensuring the strength of the electric pole, reduce the self-weight of the electric pole, and improve the crack resistance and durability of the electric pole sex
