Wood-concrete bath! Part 1

Today I want to tell you about one of its facilities. This bath constructed of wood-concrete blocks dimensions 250h300h500 mm. Fundam bath is a monolithic plate with insulated sleeves device under communication. slab thickness 200 mm, along the perimeter of the supporting walls are filled with reinforcement ribs 300x300 mm. The entire plate is reinforced fittings AIII 12 mm.

Let me explain what AIII and unlike AI reinforcement. It's simple enough. AIII - it reflonaya fittings, and AI - smooth. Smooth fittings are often used for the manufacture of collars and "frogs". Clamps are used for frames and a device for fixing the longitudinal rebars at equal distances from each other. "Frogs" - are special devices that are used for the separation of the upper reinforcement mesh from the bottom to the desired length.

Once assembled formwork, arranged all the necessary liners for communications made metal screen with a mesh of 200x200 mm increments, waiting for the concrete to build our platform. We ordered a mixer and concrete pump, because the direct entrance to the base of the mixer there is no supply of concrete had to be carried out with the road. From the road to the basement of 20 meters. On this concrete was ordered in view of the long delivery and removal of a large boom. To this foundation, we used concrete grade B25
or in the old classification M350.

Many comments criticize me for using such a durable characteristics of concrete for such a small construction. But this matter. And the degree of responsibility at all different. Concrete accepted. Stove bathed in level, the maximum deflection is 5 mm slabs horizontally.

Now go to the masonry walls. Masonry walls made of wood-concrete blocks N250h300h500. The partitions of the first floor are made of wood-concrete blocks N250h200h500. For those who do not know the abbreviation N250h300h500 - is interpreted as follows: H250 - points to a height of 250 mm unit 300 - the block thickness in mm, and 500 - this block length in said same millimeters. All bridge window and door openings are made of hot-rolled equal angles which primed special waterproofing composition.

I talk a little about the material itself. Wood-concrete blocks - is a highly energy-efficient material made of pine chips, high grades of cement and various binder additives. Arblolitovye blocks have good insulating properties. But with masonry walls of this material, there are several characteristics that differ greatly from traditional masonry. The thickness of masonry joints is an average of 10 mm! What??? - you might say. And that's why...

Wood-concrete blocks stacked to the cement mortar. To avoid thermal bridges the gap special is done in such a seam. Personally, we filled this gap with foam for better insulation. But there is an a lot of opinions on this issue as well as on ways of laying of the walls.

Place Like if it was interesting. Write in the comments whether you have experience in the construction of wood-concrete blocks?
