PLAN files US Provisional Patent Application for Planet LCD CementTM  Progressive Planet has developed a third supplementary cementing material (SCM) which it has named Planet LCD Cement. In an effort to reduce the carbon footprint of concrete, global cement companies have begun producing a type of cement called Limestone Calcined Clay Cement (LC3). LC3 cements use natural pozzolans high in alumina such as metakaolin along with limestone and gypsum to replace up to 50% of Portland cement in concrete. LC3 cements are known to be highly reactive based on the fact that they contain high levels of alumina.Progressive Planet believes it is the first company to develop Limestone Calcined Diatomite (LCD). LCD has many times lower amounts of alumina than LC3 Cements and Progressive Planet has successfully substituted up to 50% of Portland with Planet LCD Cement with strong compressive strength in tests on mortar cubes. Current testing has demonstrated strong compressive strength replacing Portland cement on a "weight for weight" basis at 20%, 35%, and 50% replacement with all compressive strengths passing ASTM C618."Planet LCD Cement uses diatomaceous earth, limestone, and gypsum, all which are plentiful materials," stated Steve Harpur, CEO. "We have created a highly reactive cement without metakaolin. Waste diatomaceous earth powders sell for a fraction of the cost of metakaolin. This opens up opportunities to utilize waste diatomaceous earth powders globally to replace 50% of Portland with Planet LCD Cement," further stated Harpur."Planet LCD Cement is a scalable solution that creates stronger cement than the status quo," stated Dr. Doug Brown, CTO. "The reactivity of silica in these naturally occurring rocks is exceptional for the production of natural pozzolans."Planet LCD Cement was invented by Ste...
