What is the number of dry mortar used for tiling, and what is the specific gravity

The ratio of cement and sand is 1 to 2, in line with the relevant provisions of the state, if the proportion is reduced, the cement is more, it can enhance the cohesion, when paving the wall tiles, you can use the ratio of 1 to 1 to mix cement and sand, but this will increase part of the cost, so the cement must be prepared in advance, when paving the floor tiles, the proportion of the two materials can be increased to 1 to 2 or 1 to 3, because most of the house floor needs to be leveled with cement mortar, Therefore, when laying floor tiles, it can play a firm role without too much cement, and at the same time, in order to prevent the cement from shrinking too much and causing greater tensile stress to crack the tiles, it is advisable to use low-grade cement.

Interior glazed wall tile construction steps.

1. Leveling: When paving wall tiles, the surface of the paved wall should be treated, the surface dirt should be removed, and sprinkled with water to moisten, and then leveled with cement mortar, and then paved after the leveling layer is completely dry.

2. Elastic line: According to the requirements of the design and paving pattern, determine the brick arrangement scheme, and pop up the brick position line on the dry leveling layer.

3. Paving: Soak the wall tiles in clean water for about one hour, subject to no bubbles; Then take out, wipe dry the water stains, spray enough water on the leveling layer, and then evenly smear about 1:2 cement mortar on the back of the brick (cement with an ordinary qualified cement grade of 325 Portland cement), the mixed grade is below 200 (if the mixed mortar is too high, its later stress will cause the glaze of the brick to crack, resulting in engineering quality accidents), the thickness of the mortar is 5-6mm, and the large-scale glazed bricks are appropriately thickened, and the wooden hammer is gently patted flat to avoid hollowing. And level with a ruler at any time.

4. Trimming: After pasting a certain area, fill and scrape the brick joint with cement slurry or special grout; Finally, the dirt on the brick surface should be removed and the care should be strengthened.

Additional note: The vitrified brick wall does not need to be soaked in water, it can be directly paved, the cement mortar on the back should be thickened, and other aspects are roughly the same as the glazed brick.

Note: Before the tile is paved, the quality of the brick should be checked, the tile specification, model, color number, and the paving plan should be designed!

Generally, the cement marks used in building construction are all good, as for how to paste the tiles?

Now the tiles, because the tiles are getting better and better, so the water absorption rate is constantly decreasing, the traditional cement river sand can no longer meet the requirements of the tiles, and the size of the tiles is getting larger and larger, so it is more difficult to stick, so it is recommended to use professional knot materials, such as porcelain stickers to paste tiles.

Porcelain sticker is a special tile bonding material, so there is no need for wet walls, bubble bricks, supports and other steps, as long as you follow the following construction methods to do it.

1. Pour the porcelain sticker powder into clean water and stir it into a paste (mixing ratio: 20kg powder 6kg water), after stirring, it needs to stand still for about 10 minutes, and then stir slightly before use, which helps to increase the adhesion force.

2. Use a toothed scraper to apply the glue on the working surface to make it evenly distributed and form a toothed shape.

3. Knead the tiles on the top during the drying time.

When decorating the house, the ratio of tiles and cement and sand is set according to the actual situation, and the wall tiles and floor tiles. And the ratio of wall tiles and floor tiles will be different, and there will be certain differences between the formula materials and the southern materials, but in general, the ratio of cement and sand is 1:2, which is in line with national regulations.

The mass ratio of the left and right, it is recommended to use medium sand as the best.

I see that many new TX are not very clear about the proportion of cement mortar used in bricklayer construction. Below I will give a general introduction to the proportion of cement mortar in each part of my house, as well as some knowledge I learned from the workers and the Internet. I can't say it's original, I can only say that it's my summary of this aspect, and if there are any mistakes, I have to ask teachers and students to correct them, so as not to be embarrassed by experts one day.

Ha ha. First of all, let's talk about the proportion of cement mortar in my tile. Wall tiles:

My house is a 1:3 cement mortar ratio, using the tile wet paving process. Moreover, these ratios are volume ratios, which cannot be absolutely accurate on the scale, but only roughly the proportions that can be distinguished by the naked eye.

The strength of 1:3 will not break when rubbing the small cement blocks vigorously by hand after 1-2 days, while the ratio of 1:5 will break into sand powder.

This means that the strength of the cement is too low, and it is good to have a higher proportion of cement and sand for wall tiles. Some people think that since it is high, it is necessary to have pure cement, my bricklayer master's reply is that it is completely possible, but there is a premise, that is, in addition to the high cost, the ceramic tiles are also good, only good tiles can use high-grade cement, the reason is very simple, when the cement strength comes up and shrinks, the poor quality tiles will be broken by the cement. 1:

The ratio of 4 cement is cost-effective, which can ensure quality and reduce costs. Floor tiles: Floor tiles are paved using the dry paving process, which is divided into two layers of cement, and the bottom cement is relatively dry.

It feels like the humidity of tofu dregs, not the moisture of cement like a paste like sticking to the wall. The ratio is 1:4 ratio.

Lay it on the ground floor first to find a good level. Then apply 1:0 pure cement slurry on the back of the tile, put it on top of the bottom cement, and use a tool to hit the leveling.

It should be noted here that the sand used for wall tiles is often sifted by bricklayers, while the sand for floor tiles is good for bricklayers.
