What to build the house of?

The farther in the wood, the are more than guerrillas, or the Bol read councils about the choice of construction material, the more enter delusion.

This article - my attempt based on my personal practical experience to answer so rhetorical question.

In the beginning let`s agree that we are simple normal builders and we have no difficult technique which is sometimes comparable at the price with the cost of our future house.

our main tool - dexterous hands.

our assistants - both graduates of agrarian and economic technical schools.

A the main driving force - huge desire to live in own house.

First of all, it is necessary to define, at least for itself what material for us will be ideal.

1. Strong.

Of course, is not necessarily necessary to us the fortress capable is long to hold a siege betonoboyny tools or the house which will be able to sustain 12 - a mark earthquake on the Richter scale, but to live in the house where walls burst under weight of the second floor or shake from wind, to put it mildly, not comfortably if not to tell - dangerously.

2. Fire-resistant and not toxic.

Unfortunately, many at first sight good and not expensive construction stuff, at the fire almost literally add " fuel to the fire; and quite often at the same time smoke a poisonous smoke. At operation emit toxic substances in air of your house. Can promote emergence in the dwelling of fungi and a mold, harmful to the person.

Human life or health is more expensive than any construction material! It is possible to save on comfort of the house, design, the area yes you never know on what, but not on the health or even lives in any way.

3. Good heat insulator.

If you live in soft climate, for example, of Southern Europe, delete and forget this point, but if for you -30 Celsius behind a board - not the rarity, is to think very reasonably or in advance of thermal insulation of the house, or where to buy at a bargain couple of tens tons of fuel oil.

4. Cheap.

Is fine material which with ease will pass tests three above-stated points - penoalyuminiya, but it is at least ten times more expensive, for example a brick from what there is a natural question - and who will pay this banquet?

Indissolubly the durability is connected with cost, in fact, it is the same cost, it is only necessary to consider it not to building, and later.

And now let`s define material which most of all meets these requirements.

It is quite simple to deal with fire and ecological safety, having rejected all materials containing organic substances, for example a tree, plastic, polyfoams. There are, however, exceptions, for example materials on the basis of kremniyorganichesky polymers (silicones) from which products are fire-resistant and with which perfectly replace parts of a human body... but anyway, we will not forget about point 4.

It is possible to decide on low cost too, the cheapest are materials on the basis of natural mineral raw materials, for example, it as quartz, clay, limestone, mica, dolomite and many others.

But to deal with durability and thermal insulation so just it will not turn out because the material is more dense, the it is stronger, but more dense material will be worse heat insulator, we receive a two-edged sword.

the Exit is obvious - it is necessary to find golden mean, durability maximum at a heat conductivity minimum. Such golden mean is at the density of mineral construction materials, approximately equal density of the most remarkable substance in the Universe - waters, that is, the volume of such construction material borrowing as much as 1 liter of water, about 1 kilogram will have to weigh.

Most close, from the most widespread construction materials, correspond to such parameters - a hollow ceramic brick and blocks from light concrete, for example a keramzitobetona. These materials linked by cement mortar are rather strong that the wall 25 centimeters thick was capable to bear any loading arising in one - and two-storeyed houses. At winter temperatures -10, -20 and -30 degrees Celsius of a wall from these materials have to have thickness, respectively, 25, 40 and 50 centimeters.

It is possible to increase heat-shielding properties of such walls, applying warm masonry solutions to a linking of bricks or blocks, and also leaving air layers between ranks, it is a so-called kolodtsevy laying. If to fill these layers with the heat-insulating fillings, for example expanded clay or slag, then thickness of brick (block) walls can be taken minimum, equal 25 centimeters, proceeding only from requirements of durability.

At all this service life of walls of houses from brick or easily concrete blocks, at the reliable bases and correctly executed laying is almost not limited.]
