Purification decorative blocks "Washed Concrete" technology

I think most who have read the previous article, it is interesting, what eventually happened? It's one thing when you're on the thumb are made without significant pauses in the work. And another thing, when you want to start the new season, some small things forgotten, and even added a new form.

In the last article I forgot to mention the important points.

1. All work must be performed in a fully rubberized gloves. Concrete - alkaline environment, it corrodes the skin, it dries up, crack.

2. All forms need to vibrate. Manually is inefficient. To vibrate the concrete when pouring the foundation previously acquired vibrator. They and vibrated concrete, the forms themselves (in contact with a mace). In fact, the vibration table is not needed.

Vibrating table I is also available, but raise serious forms with concrete, and then they lowered to the floor, set in form - hard. Especially patterned forms for pillars - without a bottom, standing on plywood.

So, he blocks the cleaning process:

The first step is poured water from a bottle. I merge into a conventional bucket. Pulled out of the concrete easily. Obtained after slightly wrinkled. But it must be like a balloon to inflate them. PET bottles of beverages are thick plastic - they are difficult to rectify. A purchased this year in the production of new 2n - thinner. It is easy to return to them their shape.

Origin excavated block. Slightly skroshilsya angle. I thought that, due to insufficient high temperature in the greenhouse Workshop - concrete could not be cured. But in the subsequent blocks and shapes I realized that everything is fine. After purification, the topsheet - this cleavage is imperceptible.

Cover for sampling units before purification. Removed by parsing the two faces in the shape of (the shape shown in previous articles).

Brush with metal bristles removed neskhvativshiysya upper layer of concrete with blocks and laundered surface. Products were obtained from the first. I am pleased.

The result is influenced by many factors. Such as the:

- quality of the concrete (cement content therein and the amount of water);

- temperature during the day, when the products are gaining strength. At temperatures below 10 c. concrete can not gain sufficient strength blocks will crumble when they are processed;

- retarder concentration applied to the surface shapes.

column cover. Slightly loosen the edge shape and the product can be easily removed.

It overlays on metal poles fence made of profiled sheet. Blockouts left until the optimal set of concrete strength.

Cover for these pillars. Live looks a bit better, the picture is not transmitted picture. These pyramidal caps inserted fittings (at large), and a long screw (the little) - for fixing on the poles.

Valves will be inserted into the solution inlaid filling unit. A screw is screwed into the plastic pole cover.

Cleansed two brushes. Plus this one - there is no dirt. I remember the first plate for permanent formwork foundation I laundered the water was dirty. There is also a big disadvantage - a very long and laborious.

How to drill a well, and there will be issues with water, think about what would have to buy a car wash.

Scuff metal fence posts obtain excellent quality - no spalling, deep texture (there was an optimum green concrete layer).

Surface approach. It was already evening, all the colors of the camera does not transmit.

I moved to the recess and purification for basic lot fence blocks.

After recesses PET bottles here are such neat non-through holes. Cross-cutting and do not need - that would not fall through when installing the solution. Longitudinal blocks are stacked up bevels.

Blocks removed from the mold quite easily and without chipping.

In the purification process of the sand bed for typesetting block column. Retarder interesting works. The impression is that he seems to be replacing the concrete from a thin layer of jelly, leaving only sand.

In one purification unit takes about five minutes on average.

Soskladiroval and laundered in a workshop in which during the day temperature is increased, in sunny weather above 30 degrees. Cover with plastic wrap. Concrete in these conditions is gaining greater strength and it is faster. By type of autoclave aerated concrete. Only need to be watered with water.

The next stage of work - is the cleaning of all forms of residual concrete, build forms of laminated plywood application retarder. And you have to fill the bottle with water-blockouts again.

On pouring and finishing to the desired type of concrete lining on pillars it takes a long time. I decided to deal with them only on weekends.
