Problems solved by technology

At present, concrete poles for power transmission mainly use prestressed poles made of ordinary concrete, partially prestressed poles and ordinary concrete poles, which have the advantages of heavy poles, high transportation costs, large-scale equipment hoisting for installation, and resistance to acid, alkali and salt corrosion. Poor resistance, poor freeze-thaw resistance, large temperature difference, easy to produce shrinkage cracks, etc., and the excessive weight of ordinary poles, especially for natural disasters and other emergency repairs, brings great inconvenience

Abstract

The invention relates to the technical field of concrete and more concretely relates to lightweight high-strength ceramsite concrete and a concrete pole. The lightweight high-strength ceramsite concrete is prepared from raw materials including the following ingredients in parts by mass: 380-420 parts of silicate cement, 45-53 parts of silica fume, 75-85 parts of slag powder, 560-620 parts of stone powder sand with the grain diameter of 0.16-4.75mm, 650-715 parts of shale ceramsite with the grain diameter of 5-20mm, 2.8-3.4 parts of efficient water reducing agent with the water reducing ratio higher than 30%, 115-126 parts of water and 0.4-0.6 part of polypropylene fiber. The concrete pole is formed through uniformly distributing the lightweight high-strength ceramsite concrete on a reinforcing steel bar net. According to the lightweight high-strength annular ceramsite concrete pole, the material source is wide, and a large amount of mineral waste is doped; and the weight is light, the carbonization resistance is good, the freeze-thaw resistance is good, the compressive strength is high, and the crack resistant strength is good.

Description

technical field [0001] The invention relates to the technical field of concrete, more specifically, to a lightweight high-strength ceramsite concrete and a concrete pole. Background technique [0002] High-strength ceramsite concrete is a kind of light-weight aggregate concrete. The current use strength range is LC5.0~LC60. Due to its high strength, light bulk density, not easy to crack due to temperature difference, small self-shrinkage, good freeze-thaw resistance, after forming concrete Being able to form self-maintenance and other characteristics, it is one of the main energy-saving and environmental protection materials that are currently being promoted in the new century. Ceramsite concrete began to develop in my country in the 1960s, mainly used for thermal insulation materials and non-load-bearing structures. In the late 1990s, with the rapid development of foreign technology, it also gradually developed rapidly and has C50 grade high-strength ceramsite concrete. . ...
