Advice 1: How to calculate the number of cinder block

In the construction of buildings of various kinds is now widely used cinder blocks or masonry units, which are produced by the method of vibratory compaction of concrete in a particular form. Getting started building a house or garage, you must correctly calculate the amount of building material to avoid unwarranted cost overruns.

  • calculator.
Determine the dimensions of your cinder blocks. The standard unit has dimensions of mm. 390х190х188 Can also meet up with cinder block partition sizes 390х120х188 mm. If you use a different standard or produce this construction material themselves, make preliminary measurements of the product.
Define a method of stacking cinder blocks in the construction of wall structures. From how you place the stone in the masonry will depend on the wall thickness and, consequently, consumption. You value that face of the block, which is external in the construction of the wall, as its size will directly affect the amount of material.
Let's say you intend to build a wall in pablaka. Calculate the area of the broad faces of the block. To do this, multiply the unit length by the width, for example, 390х190 mm. You will receive 74100 square mm or close to 0, 074 sq. m.
To calculate the flow rate of the cinder blocks for one square meter of wall, divide the unit on the result obtained, expressed in square meters: 1 / 0,074 = 13,51. Rounding the value, you will receive 14. As many blocks you'll need for the construction of one square meter of wall structures.
Let's say you intend to put cinder blocks in the garage with dimensions of 5x7 m and a height of 2.5 m. Calculate the perimeter of the construction folded it length and width and multiplying this value by two. You will receive: (5 + 7) x 2 = 24 m. Now find the area of the walls, multiplying the perimeter by the height of the garage: 24 x 2.5 = 60 sq. m. Subtract from this value the goal area, which, for example, will be: 3.2 x 2.5 = 8,75 sq. m. In the end you get the result 51,25 sq. m, which is the area of all walls of the garage.
Given the number of blocks per 1 sq m of facilities, calculate the required amount of material. For this 51,25 multiply by 14. Thus, the erection of walls of garage you will need about 717 cinder blocks. By purchasing the material, provide a reasonable reserve in case of marriage or possible damage to the units in the process.

Advice 2: How to calculate amount of concrete

The exact calculation of quantity of concreteto be laid in the formwork – one of the conditions for competent performance of construction works. Excess concrete, as a rule, use nowhere. The mixer will take either pre-ordered and paid for the concrete, or dumped it to a specified location, creating a monument to your stupidity. Violation of the same construction technology due to the lack of concrete will lead to even more serious consequences. Consider the example of a strip Foundation, how to avoid such errors.

Ready-mixed concrete of various grades, which is a semi-liquid mass, depending on its structure has unequal shrink – the smaller the cement and water, the less significant changes of volumeand of the concrete during curing. In addition, the magnitude of the shrinkage of concrete is influenced by other factors, such as the way of the seal: when shtykovaniem shovel shrinkage is smaller than when sealing concrete with deep vibrator. When calculating the required amount of concrete generally use the same average coefficient of shrinkage equal to 1,015-1,02.
Calculate the volume of the pre-concreted design, according to the draft (sketch). To do this, multiply the width, height and length of the Foundation.
Check after the construction of the formwork according to height, width and length of the Foundation with design values. Small deviations of the dimensions in a big way lead to a substantial increase in the required amount of concrete. Use of inventory formwork of steel frames and plywood allows to minimize these errors.
Multiply the resulting volume by the shrinkage factor.
Subtract from this value the volume of all openings and niches for engineering services (pipes, ducts). To do this, you need to calculate the appropriate volume according to the formula for determining the volume of a cylinder (area of a circle multiply the height) or a parallelepiped (length multiplied by width and height). The resulting value will be the amount of concretethat is required to fill the design.
In order to avoid errors in the calculations, all measurements (length, width and height of the Foundation and openings in it) should be in the same units – metres.

It is very important that in case of using wooden formwork, it was the most aligned and tightly fastened, otherwise the formwork may bursting from the weight of poured concrete. Considerable importance is the absence of gaps between the boards, which will leak water seal pour of concrete, which also leads to change in a big way the shrinkage factor.
Useful advice
When filling large volumes, concrete is always better to order a little more. Just in case on site possible to build the formwork for typical concrete structures, in which, if anything, you can merge the rests of the concrete. It can be Foundation blocks, lintels and other precast products that will sooner or later be used.

Advice 3: How to calculate how much you will need linoleum

Before you start repairs in the apartment necessary to calculate the required area of the linoleum, not relying on advisers from the store. Otherwise, when laying may result in a shortage of material, and the linoleum will have to Supplement with scraps from the main roll or not to change.
How to calculate how much you will need linoleum

Choose linoleum for premises

For large apartment perfect linoleum surround the figure, but if you want to save money and to facilitate its installation, it is better to give preference to coating with a geometric print. Standard width rolls in the store has N meter size, so if your room has non-standard value, you will have to take a few strips to hide the gaps on the floor by the skirting boards or furniture.
The ideal solution would be to buy linoleum with a small allowance, calculated on the curvature of the walls, and the final prirezku you can perform at home.

Linoleum with a geometric pattern makes it much easier task, allowing easy to pick up two pieces at numerous joints in the apartment. If you have a narrow hallway, footage of which is not more than five feet, need to purchase coverage with an abstract pattern, the width of which reaches three meters, and cut it in half. However, in the case of a pattern in a specified direction (such as "floorboard"), you will not be able accurately and successfully join the band.

How to calculate the area of the linoleum

To see how much material you need to cover the floor, take a ten-meter tape measure, a pencil, a calculator and a sheet of paper. Measure the width and length of your room, given the depth of doorways in its longest part. Then add to the obtained results of ten centimeters and record the measurements on paper. Now multiply the results of the length and width to calculate the area of the room.
Remember that the data obtained after these calculations, not the final linoleum will have to be brought together.

To joints coverage as much as possible, you need to draw a floor plan, taking into account when drawing the previously obtained dimensions. Mark in terms of all communication pipes, ledges and closets. Look at the drawing and define the width of the linoleum, which should be enough for your apartment. Usually it comes in sizes from a half to four meters in increments of two feet. Perfect width linoleum – one in which it will go solid cloth, not requiring a connection separate pieces.

Selecting a suitable material and accurately calculate its width along the walls and baseboards, lay the linoleum in the room and do the fine trimming along walls and in corners and niches, and fit it to the desired size. The work on laying linoleum over.
