High-strength concrete composite material as well as preparation method and application thereof

Abstract

The invention discloses a high-strength concrete composite material as well as a preparation method and an application thereof, and relates to a concrete material. The high-strength concrete composite material comprises the following components in percentage by weight: 4.9-5.3% of water, 17-19% of cement, 15-25% of sand, 2.0-2.4% of silicon ash, 2.0-3.0% of quartz powder, 0.18-0.20% of high efficiency water reducing agent, 45-55% of calcined alumina aggregate, 0.1-0.85% of chopped aramid fiber and 0.5-4.0% of fiber cloth. The preparation method comprises the following steps: (1) stirring; (2) forming; and (3) curing. The high-strength concrete composite material is a non-metal material which can not be rusted; the electromagnetic insulation property of the high-strength concrete composite material is favorable, thus the high-strength concrete composite material can fully display the advantage under the condition that the structure requires no magnetic disturbance; the elastic modulus of the high-strength concrete composite material is similar to that of normal concrete, and the prepared anchorage device and other accessories can be well matched with other components; and due to light weight, the high-strength concrete composite material can lower the structure dead-weight and manufacturing cost.

Description

technical field [0001] The invention relates to a concrete material, in particular to a high-strength concrete composite material and its preparation method and application. Background technique [0002] The weakness of steel as a structural material has three aspects: First, corrosion changes the chemical composition of structural materials, causing the steel to lose its original mechanical properties, which seriously affects the durability of the structure; The demand is higher, and steel beams and steel bars (steel wire) are difficult to meet the requirements; third, steel is a consumable resource and is not renewable. Focusing on the long-term development of human beings, it is the general trend to choose non-metallic materials for construction materials instead of steel. [0003] Non-metallic materials have excellent properties such as no rust, no magnetism, good electromagnetic insulation, light weight and high strength. Compared with steel, they have unique properties...

Problems solved by technology

[0005] The above-mentioned anchors all use metal parts to varying degrees, and because the metal parts themselves will rust, the unique advantages of FRP cannot be fully utilized

The applicant has developed an FRP anchor (ZL200910273443.7), which can meet the needs of the project, but the cost is high. Therefore, further research on high-strength concrete anchors is required. The concrete anchors do not contain steel materials
