White fiber high-performance C50 pump concrete

Abstract

The invention discloses white fiber high-performance C50 pump concrete, which comprises the following components: cement, fly ash, slag micro-powder, silica fume, basalt fiber, quartz sand, macadam, an additive, mixing water and titanium dioxide pigment. The white fiber high-performance fair-faced concrete prepared by the invention has the following characteristics: the white fiber high-performance fair-faced concrete has relatively strong tensile strength and ductility, the appearance is white and does not change along with time, the surface performance of fair-faced concrete is realized, bubbles are few, and color is uniform. The concrete disclosed by the invention is used as a concrete base material for a structure, mainly plays roles in pressure resistance, crack resistance, permeationresistance and attractiveness, and has a relatively high application value in the field of building and bridge structure concrete.

Description

technical field [0001] The invention belongs to the field of building and tower column structural materials, and relates to a high-strength, durable, crack-resistant mass-produced fair-faced concrete, in particular to a concrete that is suitable for long-span bridge cable tower projects and other gradient concrete structure projects. White fiber high performance C50 pumped concrete. Background technique [0002] As a key component of a cable-stayed bridge, concrete pylons are subject to performance limitations of traditional concrete materials and the impact of harsh construction environments, resulting in pockmarks and cracks on the surface of concrete pylons, which reduce the safety, applicability and durability of the service period. At the same time, cable-stayed bridges are mostly used as landscape landmark buildings. The traditional gray concrete towers are not aesthetically pleasing, which affects the coordination of the bridge with the natural and social environment....

[0002] As a key component of a cable-stayed bridge, concrete pylons are subject to performance limitations of traditional concrete materials and the impact of harsh construction environments, resulting in pockmarks and cracks on the surface of concrete pylons, which reduces the safety, applicability and durability of the service period.

At the same time, cable-stayed bridges are mostly used as landscape landmark buildings. The traditional gray concrete towers are not aesthetically pleasing, which affects the coordination of the bridge with the natural and social environment. It requires secondary protection and decoration, which increases a lot of manpower, material resources and time costs. The post-maintenance cost of the column is higher
