Problems solved by technology

[0003] For bridges located in mountainous rivers, the pier concrete is vulnerable to damage caused by flood erosion and the impact and abrasion of sediment, pebbles, boulders and other objects driven by the flood, thus affecting the structural safety performance
Previously, such bridge piers were protected by steel casings, but the steel itself is prone to corrosion and has insufficient service life, which also affects the beauty of the bridge.

Abstract

The invention discloses a C100 anti-abrasion thin-wall concrete and a preparation method thereof, and belongs to the field of concretes. The concrete is composed of, by weight, 495 parts of cement, 51 parts of mineral powder, 90 parts of fly ash, 71 parts of silica fume, 1020 parts of coarse aggregate, 703 parts of fine aggregate, 21.3 parts of a water reducing agent, 35 parts of steel fiber, 0.8 part of basalt fiber and 134 parts of water. The C100 anti-abrasion thin-wall concrete provided by the invention has excellent performances such as high strength, high density, low porosity, high deformation resistance, high impermeability, high abrasion resistance and the like.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a C100 anti-abrasion thin-walled concrete and a preparation method thereof. Background technique [0002] Mountainous rivers are prone to flash floods after heavy rains. Flash floods cause a sharp increase in flow and enhanced hydraulic power, which drives the movement of rocks, sand and pebbles at the bottom of the river. Therefore, floating pebbles are common in mountainous rivers. [0003] For bridges located in mountainous rivers, the pier concrete is vulnerable to damage caused by flood erosion and the impact and abrasion of sediment, pebbles, boulders and other objects brought by the flood, thus affecting the structural safety performance. Previously, such bridge piers were protected by steel casings, but the steel itself is prone to corrosion and has insufficient service life, which also affects the beauty of the bridge. [0004] With the continuous advancement of technologies suc...
