Technical web pages are listed below which are suited to more advanced readers. They are essentially the same as they were on the Tececo web site in 2008 and we suggest navigating to http://www.tececo.com/technical.php for a more up to date list.
|Advances in TecEco Technology - 10 Years on||This page summarises advances in TecEco Technology over the last 10 years with a focus on exemplars.|
|Changing Permissions and Rewards Systems to Get Ready for Carbon Trading and Meet the Sustainability Challenge||This page discusses ways to green concrete profitably and explains how prescription based standards and green point criteria as they are currently worded are a hinderance rather than help|
|Fire Resistant Buildings using TecEco Binders||
The recent bushfires in Australia make it more urgent to develop composites that have both "R" value and specific heat capacity. This page discusses the causes and options for dealing with bushfires.
|Ground Limestone in Portland Cement - A Good Idea or Lost Opportunity||From a particle packing perspective ground limestone is a good idea. But what the about the chemistry? Find out what we think on this page.|
|Magnesium Hydroxide Nano Composites||This page discusses the amazing ability of magnesium hydroxide to form complex layered double hydroxide (LDH) compounds with many other substances. This property is important because it is why magnesium hydroxide is so useful to lock up wastes and is related to how it can bonds so easily with other substances|
|Other Magnesium Minerals in Concretes||Magnesium occurs in many different forms in cements. The only one that is dangerous is Periclase which is a high temperature mineral formed if magnesium is present during the clinkering process. This page describes some of these other forms.|
|Permecocrete Porous Concrete||This page discusses in depth the water cycle, salinity, pollution and water shortages and the Permecocrete solution.|
|Reactive Magnesia Cements - A Blog||
Comments by our managing director about his experiences with reactive magnesia in hydraulic cements.
|Reactive Magnesia - A Theoretical Explanation of Properties||
Reactive magnesia is the most powerful new tool in cement chemistry today and on this page we explain the unique properties it imparts to concrete..
|Rheological and Shrinkage Reduction Affects of Adding Reactive Magnesia to Concretes||
TecEco cements containing reactive magnesia have a thixotropic rheology with low sag and high stick. They do not bleed much and have low shrinkage. There are physical and chemical reasons for these characteristics that are explained on this page.
|The Importance of Temperature for the Manufacture of Reactive Magnesia||TecEco prefer to use reactive magnesia which is essentially amorphous magnesia with low lattice energy made at low temperatures and finely ground.|
|The Use of MgO by the Chinese||The Chinese have been using magnesia in concretes, particularly for Dam manufacture since the 1970’s and this page explains the difference between their technology and ours.|
|TecEco Cements||We are striving all the time to explain TecEco cements to others. This page is a more comprehensive attempt to communicate the salient features to people like engineers..|
|The Importance of Particle Packing||
Particle packing is taught as part of basic materials processing courses at engineering schools but is poorly understood in the concrete industry. An understanding of the basics is important when making concrete and TecSoft Pty. Ltd., an associated company of TecEco are working on software that will incorporate the science of particle packing as the lack of understanding is proving a problem for the implementation of our cements.
