Embodiment 1

[0025] A kind of imitation yellow rust stone cast-in-place fair-faced concrete blind strip provided by the present invention, according to parts by weight, its raw material composition comprises the following components:

[0026] 100 parts of white cement, 20 parts of mineral powder, 57 parts of fast-hardening and finely ground cement, 0.2 parts of pigment yellow powder, 0.009 parts of pigment red powder, 9 parts of silica fume, 2 parts of water reducing agent, 71 parts of 20-40 mesh river sand, 8- 42 parts of 10 mesh river sand, 97 parts of 10-20 mesh river sand, 0.2 part of polypropylene fiber, 0.03 part of retarder, 0.08 part of water retaining agent, 48 parts of water.

[0027] Among them, the white cement is 52.5 grade white cement, and the mineral powder is 800 mesh mineral powder.

[0028] The preparation method of each component in the present invention: each component except water is pre-mixed and deployed in the factory according to the proportion, and the pre-mixed ...

Embodiment 2

[0040] This embodiment is consistent with the preparation method of embodiment 1,

[0041] Its difference is with: what this embodiment provides is a kind of sesame ash cast-in-place fair-faced concrete blind strip, and according to parts by weight, its raw material composition comprises the following components:

Abstract

The invention provides a cast-in-place fair-faced concrete blind strip and a manufacturing method thereof. The method comprises the steps of a base layer treatment step, a blind strip mold laying step, a blind strip forming step and a blind strip surface treatment step. Due to the adoption of the new base layer treatment method, the bonding force between the blind strip and the base layer is effectively improved, and the problem that the whole blind strip falls off due to an existing construction technology is remarkably solved. According to the manufacturing method, the required construction time is short, and the requirements of quick construction and quick use of the blind strip are met. Meanwhile, in the manufacturing method, a special treatment method is adopted for the surface of the formed blind strip, the durability of the blind strip is remarkably improved, and the service life of the whole blind sidewalk is further prolonged.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a cast-in-place concrete blind strip and a manufacturing method thereof. Background technique [0002] As an important barrier-free facility in the city, the blind path provides guidance and convenience for the blind to travel. Whether the city's blind road construction is sound can reflect the degree of civilization development of a city. At present, the production materials and methods of the whole block of tactile bricks have been developed relatively maturely, which can meet the needs of most tactile paving. However, in the process of laying blind roads in cities, sometimes some road sections are not suitable for laying blind road bricks. At the same time, it is difficult to completely avoid all kinds of manhole covers when laying blind roads. Therefore, it is necessary to lay blind strips on these road sections and manhole covers. continuity. [0003] At presen...
