Is the climate changing?
If yes, is climate change caused or accelerated by CO2 emissions? The debate over these questions is as intensive as ever. Fewer CO2 emissions! That is certainly one aim of environmental policy. The use of slag products advances this aim.
Carbon dioxide / CO2
Carbon dioxide has no smell and no taste. It cannot really be seen, either, except for example as bubbles in beer, lemonade or mineral water what bubbles is carbon dioxide (CO2). The CO2 either comes from fermentations (beer and champagne) or it is forced into the the drinks from pressurised tanks (lemonade). CO2 is created by the combustion of substances that contain carbon. Petrol, coal, fuel oil all burn with oxygen from air to make carbon dioxide. Critical voices describes CO2 as a greenhouse gas, because it is blamed for the increase in the temperature of the Earth.
The debate over the causes continues. But the fact remains that most industrialised countries have committed to <<less CO2>> - the use of granulated blast furnace slag makes a perceptible contribution to this goal.
Using natural stone means quarrying it from natural sources. Natural stone can by replaced by slag products , a contribution to protecting the landscape.
Slag - contributing to keeping Nature intact
Natural stone,... that sounds very natural. But using natural stone does not automatically mean protecting nature or the landscape.
Natural stone has to be exploited. In quarries.
They blast there with dynamite. Bulldozers, big vehicles and powerful machines are used for quarrying natural stone.
Slag products instead of natural stone!
Natural stone , that sounds very ecological, very natural. Basalt, granite, diabase, these are all natural varieties of stone that have useful characteristics. But to use them, they have to be quarried. This means quarries, blasting, bulldozers and a degree of non-reusable waste. In many fields of application natural stone can be replaced with slag products.
Replacing natural stones with slag products
There are fields of applications in which natural stone is the right choice. The edge of garden path look absolutely great with pale gray granite bordering. But in many other fields of application, natural stone can be replaced. Slag products are just as hard, last just as long and and are generally significantly more cost-effective. It does not always have to be natural stone.
In the construction of roads, for example, the traditional natural stone fine aggregates are increasingly being replaced with slag products. For the paving of paths, too, slag products are being used ever more frequently.
