Concrete fragmentation is one of the newest and still rare methods for applying concrete coating to the concrete surface. Apply concrete in layers (one layer after another) under pressure from compressed air using a special installation. It is called torque-installation. It is usually used in industrial volumes of construction, when not only the rate of concrete is important, but also its quality. If you need topographic survey of the area, then we advise you to follow the following link. Topographic shooting and other geodetic services can be ordered by the above link.
Sand, cement, powder -forming substances, and some other additives are covered in the machine. Then they are mixed there and are supplied along a special hose in the nozzle, where they fall in a ready -made, wet form. One layer of fragmented concrete is no more than one and a half centimeters. This is necessary for the accurate and accurate application of subsequent layers of concrete.
Concrete, applied by fragmentation, has a number of advantages:
– The thickness of the finished layer of concrete upon completion of work is only a few centimeters;
– elasticity (and therefore extensibility and resistance to damage) increases by 60 % compared to ordinary concrete;
– frost resistance and waterproofness also increase many times;
– and most importantly, concrete becomes much more durable both for compression and stretching.
