Standard sizes of cinder block and the calculation of the required number of construction

Artificial stone wall, or as often as it is called - a cinder block, manufactured by vibro concrete and sand mixture in special forms by which the blocks are obtained with different volumes voids inside, which causes their excellent insulating properties and ease.An important advantage of cinder block and it is quite a low cost, which led to its popularity among the construction of small buildings by private homeowners.

Dimensions and calculation rules cinder block

Before the construction usually calculates the required amount of breeze blocks, which you must know its dimensions.Thus, the standard size of cinder block, which is produced by industrial methods:

  • 390 mm in length;
  • 190 mm in width;
  • 188 mm in height.

In terms of a stone wall is equivalent to 4-5 bricks.Less common are the following sizes 400 × 200x200 mm and 395 × 195h195 mm.Actually, this industrial-sized but as cinder blocks are often made by yourself (this is no big deal), then the form can be made of a different size, the required builder.Standard size remains unchanged - 390 × 190h188, but an internal void volume can be varied so as indicated on the figure.From this perspective there are some kinds of wall stone: Hollow 40%, 30% or 20%, as well as full-bodied blocks without voids.

cinder block size ,

When calculating the required number of cinder block, we use a simple formula: for example, you need to build a wall in polbloka.In order to calculate the area wide face of the block, block length must be multiplied by the width, for example, 390 × 190 mm.It turns out 74100 square meters.mm or approximately 0, 074 sq.m.

To calculate the number of units per 1 square meter of the wall, it is necessary to divide the unit on the result, expressed in square meters.m .: 1 / 0.074 = 13.51.Round, we get the number 14. This is the number of units required for the construction of 1 sq.m.wall of the building.Then multiply 14 on your wall area, which is expected to lay out, and get the total number of blocks.
