First Graphene (ASX:FGR) said that FP McCann produced the first trial batch of 2,500 roof tiles for testing using PureGRAPH-enhanced cement supplied by its commercial partner, Breedon Group, which included the PureGRAPH graphene nanoplatelets it provided, according to a Thursday Australian bourse filing.
The trial production campaign used around 10 tonnes of the graphene-enhanced cement, the filing said. First Graphene expects the overall trial production volume to be around 10,000 tiles and the FP McCann testing program to occur over the next five months.
The cement was manufactured in a proprietary mortar formulation, specifically for roof tile production, per the filing. The addition of First Graphene's graphene results in CEM-II cement production using significantly reduced amounts of carbon-intensive clinker.
First Graphene's shares fell past 4% in recent trading on Thursday.
