Stages of building a house from silicate blocks

House of silicate blocks - the direction of the construction, which competes with the traditional "brick" approach.

Although gas silicate brick is a little more expensive, it has advantages that make an increasing number of companies and private owners of country to pay attention on the gas silicate.

Then we'll show you which blocks should be chosen as to erect walls of gas silicate, give the calculator a calculation of the amount of materials, photos and videos about the work.

Advantages and disadvantages

silicate blocks have advantages and disadvantages, and that is good - positives more than:

• ease.Gas silicate 5 times lighter than concrete.The standard block size -. 60h20h30 cm One unit replaces 22 bricks that weigh under 100 kg.As a result, the walls and the facade will be easier;
• insulation.Blocks - porous and hence their thermal insulation properties better than any other material.The thermal conductivity is only 0.12, while the brick is 0.87.Gas silicate blocks help more warm home;
• thermal storage.The unit has an interesting property: it is cool in summer and warm in winter.30 cm thick block is equal to the index of masonry bricks in 60 cm;
• strength.Silicate blocks better tolerate compression than tension.If you want to use the unit as an arched doorway or facade outside, then you need to make a reinforcing belt and struts, which are made of wood / metal, or select a larger block size;
• Sustainability.In production involving quartz sand, cement, water, lime, aluminum powder.Homogeneous mass is poured into the mold at the desired size, there occurs a reaction between lime powder and - the hydrogen is generated, which imparts porosity;
• Frost.Silicate blocks easily withstand multiple freeze-thaw cycles, 2 times more than the brick.Insulate the unit from outside and inside can be any building;
• Fire.The unit is made of non-combustible elements.It can withstand direct flame for 3 hours;
• Soundproofing.Silicate blocks with a good plaster on the facade dampens up to 65 dB of noise entering from the outside.Soundproofing the same as in 3-layer glass.The block size is also important: the more it is thicker - the better the insulation, the denser - so, on the contrary, less isolation.

Cons:

• porous structure by wetting the outside lead to the emergence of the fungus;
• instead used dowels expensive chemical anchor;
• gazosilikata house of their own hands is put only on the tape base;
• gas silicate not tolerate stretching - you need to use a reinforced belt;
• build a house in 2 floors and more demands put reinforced belt, finishing is performed with the use of other materials, carry out additional insulation, which leads to a rise in the cost of construction, especially if the house with attic and garage and has a complex façade.

Now you understand better what kind of gas silicate blocks are suitable for your buildings, which are the dimensions and what size would be more convenient for you.

units: types, calculation of the amount

Before masonry walls their hands, you need to properly perform the calculation of the required number of blocks.

amount of calculation can be performed using a calculator: enter any necessary design data of the perimeter, the number of windows, doors, openings dimensions, the height of the box, the thickness of the masonry and joint dimensions.

calculator outputs the result to an accuracy of 5-10%, because the payment required to purchase units in excess of a specified amount of 5-10%.

are the following brands of silicate blocks:

• D 300: the figure in the designation indicates the density - 300 km / m3.Thermal conductivity of 0.08 W / m • ° C.Place it under the insulation and the creation of ceilings;
• D 400: thermal conductivity - 0.096 W / m • ° C, serves the same purpose as the D 300;
• D 500: thermal conductivity of 0.12 W / m • ° C.This unit can be used for the exterior walls of the houses, where additional insulation is not provided;
• D 600: thermal conductivity of 0.14 W / m • ° C.Suitable for construction without thermal insulation.However, the thickness must be greater than the standard.Also, this unit shows the construction of buildings with curtain walls;
• D 700: thermal conductivity - 0.17 W / m • ° C.The unit is suitable for load-bearing walls and partitions.For the outer wall is used only if there is additional insulation.

Selection guide:

• brand 200-300 - as the insulation of the facade, exterior finishing;
• 400-600 - for the single-storey houses, non-structural and load-bearing walls (any calculator to the default network expanse is referring to the blocks in this category);
• 500-700 - for objects from a height of 3 floors, with attic;
• 700 - is used for reinforcing the belt.

house building

start building the walls with his own hands.First you need to build a strip foundation (see video below).

Step 1 - put the foundation

Running of the 200 th grade of concrete cement, coarse sand and gravel mixed in a ratio of 1 to 2 to 2.5.

also need:

1. formwork board;
2. wire to reinforce the foundation;
3. sand.

Before doing all the work necessary to order geodetic land survey.Then it is necessary to calculate the amount of material foundation and a fill (as an option - use the calculator for strip foundation).

to cut off the top of the marking 15 cm of soil, define the first corner, we arrange pegs.Then stretch the rope from the peg, mark the following angles.

Sticking corners of a square, completes a full rectangle.After measuring diagonally - they will be equal with the correct markup is similar mark extensions for the foundation.

Marked line leveled horizontally: on the same level we put planks on which the rope is pulled.

Next, you need to do land work.The hands digging a trench for the foundation from a low angle, or depth will be uneven, and the trench must be vertical.

If fray ground - set props.Then we check the level of the bottom, pour it on the bed of river sand 15 cm thick, then each layer of compacted sand, watered.

then expose the formwork, for this set of support in the corners of the timber, put the formwork: connect bars / corners of the board, put on the screws so that the bars / corners were outside and the inside of the cap.

height should be adjusted so that the level of the foundation amounted to no less than 30 cm

Video:.

for laying reinforcement under the belt cut metal rod 8-12 mm into pieces of desired length.

At a depth of 40 cm from the foundation, the bars are inserted and vertical reinforcement is attached to the formwork and between a connected wire.

now proceed directly to the pouring of the foundation.

Mix with your hands cement and river sand at the rate of 1 to 2, fill with water to the consistency of sour cream.

We take the same amount of crushed stone, sand and how much.

Fill rubble solution so that it is completely wet.Then pour the concrete: pierce rod, bar and thicken to make void from the air.

rattles when filling formwork to concrete better lay down.

Then equate rule the surface, sprinkle the top layer of sifted through a sieve and dry cement close concrete blanket and leave for 1 month to dry.

foundation after drying should be waterproofed.

Step 2 - masonry

Laying begin with the corner blocks (do not forget to perform the calculation of the amount: the calculator considers the number to reserve).

then put the guide pegs (step size of 1 m) and stretch the rope on which lay out the first line, and was equal to its level.

masonry done with bandaging of seams: blocks in the top row should be displaced is not less than 1/3 of the blocks below.

Video:

Instead of cement using a special glue.Each 4-th series is reinforced, as the times are Stroebe recess with his hands around the perimeter of the right in the stacked blocks and put the valve.

Valves laid in the 1st, 4th, 8th series, etc.Power put on adhesive mortar notched trowel.Make sure when laying 2 block glued butt, bottom, and top when laying the next series.If

subject masonry block longer than necessary - cut his grinder.Facade hide any flaws.
should highlight some of the features of masonry.

all openings in the house should be spread metal corners and propping struts.

also in the openings, the size of which starts from 1.5 m poured belt made of reinforced concrete, and before you build the wall, it makes sense in the shuttering to enclose the foam layer 10 cm.

banding is performed after the construction of the walls, in the walls is better to lay the gridthat when she contacted facing the wall.

wall paneling and siding - the best finish of the facade, which in addition can better insulate the house, and at the same time can only finish with gypsum plaster.

Through glue achieved finest seam - less than 3 mm.

Clay easy to prepare with his own hands:

• pour water in a bucket;
• add the dry mixture of glue;
• mix;
• observe the ratio of water to the mixture, indicated on the packaging;
• not cook the mixture all at once - just as needed.

Conclusion

We did not give step by step instructions on how to build a house of their own hands gazosilikata from scratch as completes the exterior decoration is performed insulation for the simple reason that would have made a huge text.

Note - the above described most of the nuances that arise in the design of the house of silicate blocks.
