Here, in detail, are six actions that we have developed to put us at the top of the list as regards care attached to the environment in the concrete industry.
With a mobile concrete mixer, if you only use 2.66 cubic metres of concrete out of the 3 metres that you ordered, you don’t have to empty the remaining 0.33 cubic metres in s nearby field or local landfill. Because the materials are not mixed in advance, they can be reused.
Cement up to 15 % less pollutant
Cement, a powder nearly as fine as flour, is one of the components required to make concrete. It is not necessarily the cement that causes pollution, it is the method of fabrication. Cement is basically a limestone found in a cement works. A large kiln has to be heated to a temperature almost as high as that of magma in a volcano to melt this stone. The only way to produce this heat is to use fuel. Here is the source of the pollution. The fuel that must be burnt to produce a ton of cement produces a ton of carbon dioxide. In the cement we use, there are also other materials such as silica fume powder. By integrating this powder in the cement, we can reduce the quantity of cement used and increase the material’s resistance.
“Green” Acert engines
The time when trucks—even new ones—produced a cloud of black smoke is long gone. When we modernized our equipment, we took this into consideration. Our trucks are now equipped with certified ACERT technology.
BétonMobile.com has used only biodiesel fuel since it came on the market. This is a fuel that greatly diminishes greenhouse gases and that, combined with ACERT truck engines, results in a great reduction of pollution emitted by our trucks on the road.
Smart eco-driving computer on board
In addition to the ACERT engines, our trucks have an on-board computer that constantly calculates the flow rate of fuel on the basis of cruising speed in order to reduce the quantity of diesel used to the maximum. All this without harming the vehicle’s performance. This way we decrease carbon dioxide on the highway, and also in the city, where stops are more frequent.
Possibilty to have recycled concrete as aggregates
This is not a question of reducing the amount of rocks used but of recycling concrete. When it comes time to redo the basement’s cracked floor, many people will break up the concrete slab, send it to a landfill and make a new one. Once used, the walls that serve to divert traffic on the highway suffer the same fate. And these are just a couple of examples. Our goal is, when you request it, to be able to use this crushed concrete to replace the rock aggregates in our concrete, to reduce the quantity of waste in landfills.
