What is concrete vibration?

Concrete vibration is an activity aimed at thickening and standardizing the laid concrete. It involves the use of a special concrete vibrator, whose vibration uniformly and accurately arranges the concrete mixture, both in formwork (in the case of foundations) and poured freely (e.g. floors). Of course, there are different types of concrete vibrators, used depending on the amount of concrete or the way it has been laid. As the name […]

How is concrete classified?

There are several ways of classifying concrete. We will present some of them below. One of the most popular classifications of concrete is its exposure class. This parameter is the exposure of the composite and its reinforcement to environmental effects. Where no hazard is present, we are dealing with class X0. Carbonation (XC), and freezing/thawing (XF) each have 4 degrees of exposure, while chloride corrosion derived from sea water (XS),[…..]

The difference between ordinary concrete and GRC

The biggest differences between ordinary concrete and GRC relate primarily to the composition of the two composites, and consequently, their physical properties. Traditional concrete consists mainly of gravel, binder – usually cement – and water with a small amount of the necessary additives or admixtures affecting its properties. In the case of GRC, it has the added glass fiber reinforcement. At the most basic level, the difference between ordinary composite[…..]
