Bluestone can be seen in many streets and alleys. Bluestone belongs to sedimentary rock. It is not only durable, but also cheap and pollution-free. It is deeply favored by the majority of consumers. However, in daily life, buildings decorated with bluestone slabs can be seen everywhere. For example, the pavement paved with bluestone slabs and wall decoration

bluestone can be seen in many streets and alleys. Bluestone belongs to sedimentary rock. It is not only durable, but also cheap and pollution-free. It is deeply favored by the majority of consumers. However, in daily life, buildings decorated with bluestone slabs can be seen everywhere. For example, the pavement paved with bluestone slabs and wall decoration. The following editor will introduce what is bluestone slab and the paving steps of bluestone slab

what is bluestone slab

bluestone slab is scientifically called limestone. It has dense texture and medium strength. It is mainly used for ground and roof tiles in gardens. Because of the different burial conditions of rocks and the mixing of other metal oxides, a variety of colors are formed, that is, the color of bluestone slab is not a single cyan. Bluestone board is an ideal building material because of its dense texture, medium strength and easy processing. It is used for dado, ground paving and has the unique style of ancient buildings

paving steps of bluestone slab

1. Preparation: Based on the construction, it is necessary to be familiar with the size and practice of each part, and clarify the relationship between arc position, corners and other parts

2. Base course treatment: put sundries on the base course, remove the mortar stuck on the base course with a steel wire brush, and clean it up

3. Trial splicing: before paving, the bluestone slabs in each area should be trial spliced according to the pattern and color. The whole block should be aligned and placed on the edge. After the trial splicing, it should be numbered in two directions, and then placed neatly according to the number

4. Snap lines: in order to align the bluestone slabs, snap lines within the laying range, and then find out the surface elevation according to the standard height of the slab surface

5. Trial arrangement: two roads can be paved in two mutual directions. The broadband should be greater than the width of the plate, and the thickness should not be less than 5cm. In combination with the construction detail drawing and the actual size of the landscape pavement zoning, arrange the pavement plates so as to check the gaps between the plates and check the relative positions of the plates with the walls, columns, openings, tree pools, side curbs, flat curbs and other parts

6. Before trial paving, remove the plates, clean them, spray water with a watering can, and draw a cross control line according to the horizontal line of the board surface and the thickness of the mortar leveling layer required by the design. The leveling course shall be paved with dry hard cement mortar (1:2.5 dry hard cement mortar shall be used, and the degree of dryness shall be kneaded into a mass by hand and scattered on the ground). The thickness shall be controlled to be 3 ~ 4mm higher than the horizontal line of the surface course when the bluestone slab is placed. After paving, scrape it with a small bar, and then pat it with a trowel for leveling

7. Paving plate: when paving, soak the plate first. According to the control line drawn in the paving area, it can be used as a paving standard plate. The trial paving can be carried out first, that is, lift the plate, align the vertical and horizontal control lines, and lay them on the paved dry and hard mortar leveling layer. Knock the wooden base plate with a rubber hammer, press the mortar to the paving height, lift the plate aside, and check whether the mortar surface is consistent with the plates. If any void is found, fill it with mortar, and then lay it formally. First, pour a layer of plain cement slurry with a water cement ratio of 0.5 on the cement mortar bonding layer, and then lay the plate, When placing, the four corners fall down at the same time, gently hit the wooden base plate with a rubber hammer or wooden hammer, level it with a hot metal ruler according to the horizontal line, pave the first piece, and pave it in order to both sides and backward direction. After paving vertically and horizontally, there are standards, which can be paved in sections in turn

editor's summary: that's all for what is bluestone slab and the steps of bluestone slab paving. I hope it will be helpful to you. If you want to know more, you can pay attention to information
