Excuse me, what does it mean to attract investment from stone materials? How to construct stone steps?

First, I want to tell you what a stone is. Stone is a high-grade product of building decoration materials. Natural stone can be roughly divided into granite, slate, sandstone, limestone, volcanic rock and so on. With the continuous development and progress of science and technology, artificial stone products are also changing with each passing day, and the quality and beauty are no less than natural stone. With the development of architectural design, stone has become one of the important raw materials for building, decoration and road and bridge construction. Stone investment means that the finished stone should be sold. Next, I will tell you how to build stone steps! Process flow: base treatment-elastic thread-pre-paving-laying-jointing-cleaning. Main construction technical measures: 1. Grass-roots treatment: Before stone construction, the ground grass-roots should be carefully cleaned and cleaned with wire brush or steel flat shovel. Before construction, brush a layer of cement slurry bonding layer on the ground. Grass-roots treatment should meet the requirements of construction conditions. Considering the need of decoration thickness, the ground should be wetted with clear water before formal construction, but there should be no water accumulation. 2. Elastic line: Elastic vertical cross control line in the center of the construction site to check and control the position of the stone plate. Cross lines can be elastic on the ground, all the way to the bottom of the wall. After the reticle pops up on the ground, the stone frame line pops up on the ground according to the stone specifications. 3. Pre-paving: First, choose the color, texture, geometric size and surface smoothness of the stone in strict accordance with the design requirements of the drawings, and then pre-paving according to the requirements of the drawings. Adjust and exchange possible errors in pre-paving until the best effect is achieved. At the same time, it should be noted that light-colored stone and low-density stone should be coated with isolation agent on the back and around to prevent water absorption from affecting the appearance of stone surface during paving. 4. Paving: Bonding layer: Before paving mortar, clean the base, then spray water with a watering can for wetting, and brush plain cement slurry (water cement ratio is about 0.5, so as to pave with a brush). Paving mortar layer: determine the thickness of the ground leveling layer according to the horizontal control line, and use the crosshairs for vertical and horizontal control. For stone inlaying, the hard mortar of 1:4( 1:3) should be fully stirred before construction (the mortar should be hard and kneaded into a ball by hand). Spread the mixed hard mortar on the ground and beat it with a gray board. It should be noted that the mortar paving width should exceed 60 of the stone width. Paving stone: Before paving stone, pre-soak the board and dry it in the shade for later use. Try paving first, align the vertical and horizontal joints, and tap the mat board with rubber (rubber hammer is not allowed to tap the stone layout directly). After the mortar is vibrated to the paving height, move the board aside and check whether the upper surface of the mortar is consistent with the board. If there are gaps, fill them with hard mortar, and then formally pave them. Fill the mortar layer with a plain cement slurry bonding layer with a water cement ratio of 0.5. When placing, the four corners should fall at the same time. Tap the plate with a rubber hammer or a wooden hammer, control the paving elevation with a level meter, and then pave in the installation order. According to the joint requirements: when paving stone plates, the joints should be tight, generally leaving no gaps. 5. Jointing: Grouting and jointing shall be carried out 1~2 days after paving is completed. According to the color of the stone, mineral pigments with the same color are added into the cement slurry, and evenly prepared into 1: 1 dilute cement slurry, which is poured into the gap in batches with a slurry pot, or leveled with dry cement mixed with toner. After completion, the cement slurry for stone typesetting should be cleaned up with cotton silk in time and protected. Finally, I want to give you a friendly reminder! ~ Stone has radioactive certificate, please ask the dealer for it when you buy it. Don't buy without a certificate, and at the same time, pay attention to choosing class A products for home improvement! That's probably it! ~ I hope to help you! If you think my answer is good, you can give me a compliment! ~
