The secret of making their own hands

Concrete - the most famous and widely used building material. It is used for the construction of various structures, foundations, walkways. Not so long ago there was a special technology - washed concrete.

The peculiarity of this technology - the use of retarders, resulting concrete hardens slowly, and the surface is washed away.

It turns beautiful material which produces texture of stone. Implement such technology it is possible to own at home.

Can make himself:

- paving tile, track,

- flowerpots,

- stairs, curbs

- boxes, pots and so on.

Many make the blocks of concrete for the construction of washed columns of intake. It looks very nice outdoor furniture made of washed concrete.

So, you need to prepare a solution and add a small fraction filler (marble, pebble, dolomite, gravel or granite chips). When the setting time of concrete, washed with water under pressure from the top layer. The surface turns out very beautiful.

Technology

Take 2 parts sand and mixed with 1 hour. cement and fine stone. There are other ways to prepare the solution.

The secret of this unusual concrete It is to add a gel, which retards gelation. It is distributed before pouring into a mold or applied to the surface.

If a shape (e.g., tile), the spec. gel solution is poured before. If you plan to pour the solution without form, the gel is applied on top.

The gel may replace sugar syrup. Some people use detergent. But the use of the gel still better for this technology.

1. Prepare cement. Some take on 1 part 3.2 parts Portland cement. filler and 1 to 5 hours. sand.

Pick filler (major fraction) from 4-10 mm. Use a filler of different shades. You can add red and white gravel or black marble. Experiment with filler! Water is added to obtain a consistency like thick cream.

2. We are waiting for concrete hardening (about a day). Extract the product from the mold and immediately rinsed with water. Need to experiment with the time of stripping, eventually concrete pour. If previously extracted from the mold, then the factions may depart from the general form. If you overdo the product, it will be difficult to wash out.
