TECHNOLOGY EXHAUST-AGGREGATED CONCRETE
(WASHED CONCRETE - English EXPOSED AGGREGATE CONCRETE)

Any concrete surface: freshly laid or molded can be given an aesthetic and durable texture of natural stone (filler), thanks to the use of special chemicals -deactivators.This texture is not only very attractive in terms of appearance, but also gives useful properties to the concrete surface:

DURABILITY AND ABRASION RESISTANCE

One of the main advantages of exposed aggregate concrete surfaces is ih extraordinary strength becausestone fillerholds very well in dense concrete mass, leaving only 1/3 of the stone exposed. The service life of concrete is 10 years or more. This will definitely help save money in the long run and will not require regular repairs, touch-ups or replacements.

This type of concrete surface can withstand extreme weather, which is a huge plus for Russians who deal with a lot of snow and ice in winter and hot, sunny weather in summer.

WIDE CHOICE OF COLORS AND SHAPERS

Another important advantage is the wide range of colors this concrete surface can provide. You don't have to settle for gloomy black or gray when you have all the options of exposed-aggregate concrete. Tiny stones lying on the surface can be made up of a rainbow of colors that complete well with the exterior colors of the façades. On the other hand, you can also opt for contrasting colors to add flair to your exterior.

 

In addition to this, a wide range of options provide a variety of sizes of stone filler.  The texture may depend on the size (fraction) of the stone. While some stones are tiny, others are larger and can be of various shapes (rounded or chipped). The nature of the stone itself can also be different: from the simplest and most understandable river pebbles to semi-precious quartz rocks.  

AVAILABILITY OF RAW COMPONENTS

Stone chips, sand, cement and water are a set of simple components of any concrete mix. The variety and availability of mineral raw materials   is another advantage of the exposed aggregate concrete production technology. 

LOW MAINTENANCE COSTS   

Many prefer concrete surfaces with exposed aggregate because they do not require special maintenance. All you need to do is only occasionally clean the concrete surface with water.

 

In order to seal the concrete surface, protect it from oil and food contamination, fungus, mold and give it a silky sheen, we recommend treating it with a special protective coating.COLORFRESH Intensive, which works 3-5 years on horizontal surfaces and more than 10 years on vertical ones. 

ANTI-SLIP EFFECT  

An additional advantage of exposed aggregate concrete is that, due to the rough texture, it is extremely difficult slip. Thus, in a number of cases (for example, when constructing ramps, railway slabs, steps), the use of this technology is simply necessary and creates the safest coating for concrete elements.

LOW COST AND SIMPLICITY 

PRODUCTION

The production of exposed aggregate concrete does not require the use of complex machinery or additional tools, unlike other production technologies. -136bad5cf58d_

FAILURE MASKING 

Bare-aggregate concrete allows you to hide all the possible flaws in the concrete surface, which would be obvious in the case of smooth concrete. And for monolithic surfaces, this technique easily masks tire marks that appear on the surface due to intensive use.

HOW IT WORKS?

(application on the walls of the form )

Prepare the mixture

Mix stone filler, sand, cement, water andfunctional additivesin concrete mixer 

Apply deactivator

Apply to the walls of the mold suitable deactivator(depending on the size of the filler and the desired flushing depth)

Fill in the form

Fill molds with mixture. Compact the mixture, progressively
 increasing frequency, in short periods

wash away

After the concrete has completely set, wash uncured cement paste from the surface with a pressure washer

Markup

On the prepared base, make markings and install the formwork for pouring the mixture, prepare the reinforcing material

Fill formwork with mixture

Mix filler, sand, cement, water and functional additives, fill formwork with mixture, reinforce, level

Apply deactivator

Apply a suitable deactivator over the freshly laid mixture by sprayer, depending on the size of the filler and the desired depth of flushing)

wash away

After the concrete has completely set, wash uncured cement paste from the surface with a pressure washer
