TecEco - History Magnesium Cements

The history of magnesium cements goes back millenia, magnesium phosphate cements made from animal faeces or fermented plant material and magnesia were used in the great wall and in many early buildings around the world. It is also likely that magnesium sulfate or chloride type cements were used before their western invention by Stanislaus Sorel .

TecEco - History Magnesium Hydraulic Cements

History of Magnesium in Hydraulic Cements. Fortunately there is a history of magnesium in hydraulic cements and this is helping TecEco overcome dogmatic hurdles such as standards. Magnesium has been found in high percentages in many Roman concretes, and it is thought to have got there either as a contaminant in the lime that was burnt or ...

TecEco - Home

TecEco Home. My name is John Harrison and I founded TecEco in the late 90's. By 1999 I had invented and tested a magnesium cement system which included Eco-Cement that set by absorbing CO2 and in March 2002 I made it publically clear that the built environment was the ideal repository for CO2 and immense global interest ensued.

TecEco - TecEco Tec-Cement

Tec-Cement. Tec-Cements are cement blends that comprise of a hydraulic cement such as Portland cement mixed with a relatively small proportion of reactive magnesia and a pozzolan which reacts with Portlandite removing it and making more cement. They offer a solution to many of the technical problems that plague traditional cement formulations caused by the reactivity of lime (Portlandite).

Nov 01, 2014  1. Introduction. It is well known that magnesium-silicate-hydrate (M-S-H) gels form as a result of sulphate attack of concrete in the presence of magnesium ions .M-S-H is present during the later stages of sulphate attack and hence M-S-H gels are generally believed to be of limited strength , .As a result, M-S-H gel has received little attention as a potential cementing phase.
