Cemex UK launches ReadyBlock Zero zero carbon concrete block
01 February 2022UK: Cemex UK has launched ReadyBlock Zero, a zero carbon concrete block, on the UK market. The product joins the company’s Vertua reduced-CO2 product range. Cemex UK achieved zero carbon production by means of offsetting. It said that ReadyBlock Zero will help builders to meet the UK’s government’s Future Homes Standard, which requires a 75 – 80% CO2 emissions reduction in all newly built homes.
Cemex’s Europe regional urbanisation solutions director of asphalt, paving and building products Carl Platt said “We have developed the UK’s first carbon neutral concrete block to help housebuilders get ahead of the game when it comes to building low carbon homes that meet and exceed government guidelines and changes to building regulations. We want to make life easier for housebuilders to make simple sustainable choices that make large scale impacts on the often complex road to net zero. Concrete blocks are the most common structural component in the construction of UK homes, so by switching to zero carbon blocks, ReadyBlock Zero presents a huge opportunity for housebuilders to make significant carbon reductions.”
India: SCG International India has announced the launch of a joint venture with autoclaved aerated concrete block producer Bigbloc Construction. The joint venture will produce and sell lightweight concrete panels. It expects to commission a new 2.6Mm3/yr concrete panel plant in Gujarat in 2022. Bigbloc Construction holds the majority 52% stake in the venture.
SigmaRoc receives Environmental Product Declaration for Greenbloc cement-free concrete block
12 November 2021UK: SigmaRoc has announced the ratification of its Greenbloc cement-free concrete block’s environmental credentials with an Environmental Product Declaration (EPD). The EPD is a Type III environmental declaration with ISO 14025, providing full-lifecycle information on the product’s impacts. Greenbloc, an ultra-low carbon alternative to traditional concrete blocks, is the first product of its kind.
Managing Director Michael Roddy said “With the launch of Greenbloc, we believe that we can now offer architects, contractors and housebuilders a competitive, reliable and – thanks to our EPD certification – proven low-carbon alternative to ordinary Portland cement (OPC) blocks. Making the switch from traditional blocks to Greenbloc can reduce the embodied carbon of a typical three-bedroom house by 73%, saving the equivalent of 2.7t of CO2 per dwelling. It is also worth noting that we have obtained additional third-party test results against the declaration of performance certificate.” He added “The world is changing for the better, and technology is facilitating greater accessibility to materials that can bring about meaningful change for the construction industry. The reception for Greenbloc has already exceeded all expectations, and we are incredibly excited for the potential it has to offer.”
Spain/Norway: A team from Cartagen Polytechnic and Ostfold University College has demonstrated that Cementos La Cruz could reduce the cost of its concrete production by Euro1.45/m3, or Euro29,000/month by curing concrete with captured CO2. EuropaPress has reported that the use of CO2 would reduce the amount of cement required by 7 – 8%. This in turn would remove an estimated 4.6% of CO2 from the concrete’s production.
