Mecalithe in Concrete saves CO2

Mecalithe® in Concrete saves CO2

Mecalithe forms tiny needles in the concrete. Now concrete strenghtenens itself. This process is fast, concrete can be lifted quicker out of its formwork.

Mecalithe® in Concrete saves 1.5 billion tonnes of CO2. 

Production of cement supplies 3.5 billion tons of CO2 worldwide. The production of cement is bad for our milieu. Therefore MGX Group developed Houton: concrete made with wood-dust and reinforced it with Mecalithe®.

Mecalithe®

The admixture for Cement Saver (CemSaver) Mecalithe® is intended for the (prefab) concrete industry. This additive can be used as a hardening accelerator and makes it possible to considerably increase the final strength by about 30%.

What’s the secret?

Cement has hardly any fibers and therefore a tensile strength of nothing. Because of that steel must be used to reinforce the concreet.

Mecalithe forms tiny needles in the concrete. Now concrete strenghtenens itself. This process is fast, concrete can be lifted quicker out of its formwork.

MBI (concreet industry) started a pilot with founder Peter van Bakel – MGX / Suston – an agency that investigates new “concrete” concepts. This pilot showed that Mecalithe needed less cement and still yielded stronger concrete.

Inventor of the Mecalithe is Youva Raj Tyagi, professor concrete technique at the Caledonian University in Glasgow.

Green product

The ‘green concrete’ is extremely strong, and remains perfect in roads with a lot of traffic, when it freezes, and must withstand salt. The potential is enormous.

Cement is not only expensive, but also harmful to the environment, because cement must be heated to high temperatures, making it responsible for over 5% of CO2 emissions worldwide.

Less cement in concrete translates into fewer greenhouse gases.

Houton

Houton ® is concrete in which wood has been processed.

This raw material combines the positive properties of wood and concrete. Wood does not normally bond with cement because it is an organic material.

However, by adding Megatrax® to the product it is possible to make concrete containing 30 to 90% wood. 

End there is more:

If Geopolymers are added to the cement, this will reduce CO2 emissions during the cement production by 80%.
