Calculation of the amount of mortar, how to calculate the amount of grout cement slurry

Cement, medium sand, moisture content is about the same, and each cubic meter of mortar is about a cubic meter required.

Stupid, the wall chief didn't even talk about it! mortar per cubic brick.

Hello, I am glad to answer for you 1. The calculation method of the mortar used in general masonry projects is as follows: (1) The net amount of 1 cubic meter of masonry mortar (standard bricks) = the net amount of standard bricks. (2) The net amount of 1 cubic meter of standard bricks = 1 [masonry thickness x (standard brick length + ash joint thickness) x (standard brick thickness + ash joint thickness)] x 2x the number of bricks with masonry thickness.

2. The thickness of the masonry, half a brick is taken from the thick date, one brick is taken, one brick and a half is taken from the number of bricks with the thickness of the masonry, half a brick is taken, one brick is taken from 1, and one and a half is taken from the thickness of the ash joint. 6. Masonry mortar: The mortar used for masonry bricks, stones and other blocks is called masonry sand stool slurry.

Junjie masonry dry powder is formulated with high-quality cement, fine aggregate and a variety of high-performance external transport additives. It is suitable for the masonry of aerated concrete blocks, fly ash blocks, ceramsite bricks and other lightweight walls and high-absorbent materials.

Summary. Dear, hello, I am happy to answer for you, how to calculate the amount of grout cement slurry according to the pressure drop ratio to obtain the required cement weight per cubic meter, and then calculate the volume of the prestressed channel and subtract the volume of the steel strand to get the volume that needs to be grouted. If you have a volume, you can calculate the amount of cement.

Dear, hello, I'm glad to answer for you, how to calculate the amount of grout cement slurry, according to the pressure drop ratio to get the weight of each cubic meter of water Hongyan mud, and then calculate the volume of the prestressed travel channel by deducting the volume of the steel strand can get the volume that needs to be grouted. If you have a volume, you can calculate the cement with a measuring limb stool.

Through practical summary, the actual amount of grouting cement in the prestressed channel = the clearance volume of the prestressed channel (the cross-sectional area of the bellows minus the cross-sectional area of the steel hinge line and the long rubber of the pipe). The amount of prestressed cosithing cement has nothing to do with other admixtures. Just like concrete, the volume of sand + stone + water + cement is equal to cubic meters, but only 1 cubic meter of concrete can be poured.

1. Calculation basis.

1. Water-cement ratio (weight ratio).

The ratio of the weight of water to the weight of cement per unit volume is the water-cement ratio. This data is given by the design unit. Generally, the value of silver is taken as .

For the engineering design institute, the water-cement ratio is given k=i.e., water:ash =. The bulk density of water is 1t m3, so the amount of cement in each m3 cement slurry is 1t.

2. The diffusion range of cement slurry in the formation.

This grouting is to place a long grouting tube (l=) in the loose backfill layer. There are grouting holes on the side wall of the grouting flower tube, and the cement slurry is injected into the soil under the action of pressure to drive away the air and water in the soil, and its location is estimated.

The result of grouting is that the cement slurry forms a garden column in each flower tube, and the diameter of this garden pillar is d=, and the length is l=. Therefore, the grouting volume of each grouting flower tube is obtained:

v flower tube = root.

Second, the amount of cement calculation.

1. According to the porosity ratio, find the amount of cement slurry in the grouting body of each grouting flowertube.

Void ratio: e=pore volume Solid particle volume, for engineering loose newly recent backfill e=. Therefore, the volume of cement slurry in the grouting body of each flower tube is obtained: v cement slurry = root.

2. Find the amount of cement for each flower tube: W flower tube = 2t m3 root = root.

3. Find the total amount of grouting cement.

The design institute gave a total of 2788 flower tubes, from which it was obtained: total w = 2788 = 3290t.

This is a detailed method Oh pro: 1. Professional algorithm: Take the 25 square meter courtyard wall as an example:

Check the "project quota" can be seen that the plastering layer is calculated according to the thickness: 1The amount of cement is added for every 5mm increase in thickness, and the same is true for the decrease.

2.The amount of sand is added for every 5mm increase in thickness, and the same is true for reduction. In this way, you can know that your 25 square meters of courtyard wall needs to be plastered on both sides inside and outside a total of 50 square meters, calculated according to the thickness of the plastering

1.The amount of cement required is 11 bales of cement. 2.

The amount of sand required is more than 2 tons of sand. Then, the 25-square-meter wall is considered to be made of red bricks (standard bricks), with specifications of 240 115 53, that is, its volume is mortar with a ratio of 1:3 (because it is a courtyard wall, the strength requirements are slightly higher).

2.The mortar content is (the amount of cement mortar thickness per square meter, that is: 240 walls, a total of 6 cubic bricks, 4000 red bricks.

From (25 6 4000 we can see that 3200 bricks are actually needed, or we can use 128 25 = 3200 to get this value. 128 square meters is the empirical value, like many construction masters are directly calculated with this value. 1.

Therefore, the amount of mortar cement is 401kg m3, which is 13 bags. 3.The amount of sand is 1593kg m3, which is also tons.

If you build 120 walls, a total of 3 cubic bricks, you need 2000 red bricks. 1.The amount of mortar cement is 401kg m3, which is 7 bags.

3.The amount of sand is 1593kg m3, and one ton is enough.
