Al Kifah Ready Mix & Blocks updates on sustainable practices
11 September 2024Saudi Arabia: Al Kifah Ready Mix & Blocks has updated the market on its achievements in the sustainable concrete space in Saudi Arabia. The producer’s mixes include slag-based aggregates, as well as natural pozzolans and CO2 injected using equipment developed by Canada-based CarbonCure. Gulf Construction News has reported that the company's range of ultra-low CO2 ConGreen concrete products and BloGreen concrete blocks have supported projects including the Aramco Stadium project in Al Khobar, Qiddiya amusement park in Riyadh and King Salman Global Maritime Industries Complex in Jubail.
General Manager Nigel Harries said "Al Kifah Ready Mix & Blocks’ products have been widely adopted in mega and giga projects across the kingdom and have proved their high performance, thus strengthening the company’s position in the Saudi market. Al Kifah’s green solutions have unique properties that facilitate tasks on the job site through their better workability and finishability. They can be considered an all-in-one solution, offering zero wastage, zero mobilisation time, lower emissions and a smart way for supplying concrete in remote areas."
Al-Kifah Precast discusses regional growth plans
10 July 2024Saudi Arabia: Al-Kifah Precast says that it is preparing to expand into other Middle Eastern countries, having more than tripled its sales since 2020. CEO Ehab Abu Salim says that the producer was a strategic supplier of precast concrete for Red Sea Global’s Red Sea Project in Tabuk Province, and now aims to support other major projects like the Neom new city and Amaala resort, also in Tabuk Province. Gulf Construction News has reported that the company has invested in research and development to establish best practices, as in its partnership with a UK-based company to produce marine concrete elements. It has reduced its CO2 emissions through the use of alternative materials such as fibreglass, steel rebar and pozzolans.
Abu Salim said “Having a facility in the Red Sea Project was a strategic move. The plant produces all types of precast elements and we are also looking to improve the facility. We have an expansion planned; very soon it will be serving the entire region." He added “Precast technology helps to speed up projects, is more sustainable, offers higher quality, and the price is on par and sometimes even lower than using traditional construction solutions.”
Global Cement and Concrete Association announces Innovandi Open Challenge 2023 shortlist
30 June 2023World: The Global Cement and Concrete Association (GCCA) has named the 15 anticipated deliverers of low-CO2 cement and concrete production shortlisted for participation in its second Innovandi Open Challenge. The association chose the start-ups based on their potential to deliver CO2 emissions reduction in the global cement and concrete sector in line with its Concrete Future 2050 Net Zero Roadmap. The applicants are presenting their pitches to GCCA members on 30 June 2023. All those accepted will gain access to members' plants, labs, networks and expertise. The following start-ups made the Innovandi Open Challenge 2023 shortlist:
Arrakis Materials | US | Carbon negative materials for concrete |
Chement | US | Room temperature cement production |
EcoAdmix Global | UK | Nanotechnology ('HDT') for concrete |
EcoLocked | Germany | Biocarbon-based admixtures |
EnviCore | Canada | Low temperature supplementary cementitious material production |
Enzymatic | US | Carbon negative enzymatic concrete corrosion inhibition and recycling |
Louis Structures | US | Municipal solid waste-based lightweight aggregates |
MEP - SeaMix | US | Basalt fibre and graphene-based admixture |
Nano Crete | US | Graphene-enhanced CO2 sequestration |
Nanospan India | India | Graphene-based admixture |
NeoCrete | New Zealand | Nano-activator for natural pozzolans |
Queens Carbon | US | ~500°C cementitious materials production |
The Cool Corporation | UK | Carbon negative carbon nanotube-based additive for concrete |
Ultra High Materials | US | Clinkerless cement |
Versarien Graphene | UK | Graphene-based admixture ('Cementene') |
GCCA cement director and innovation lead Claude Loréa said “We received more than 70 quality applications, so drawing up a shortlist was challenging." Loréa continued "Our essential industry needs something easily scalable and affordable. Those start-ups on the list demonstrated the most potential, and we look forward to hearing more about their ideas. But we’ll also be keeping in touch with other start-ups who didn’t make this year’s shortlist, with future projects in mind.”
CR Minerals to produce pozzolans from mining waste
17 November 2022US: CR Minerals has signed a contract with mining company Rio Tinto for the supply of mineral waste from the latter's subsidiary US Borax's boron mining operations in California. CR Minerals will use the waste to produce pozzolans to replace cement in local concrete production.
CR Minerals president Jeffrey Whidden said "We have been working with Rio Tinto for several years now to bring this concept to life. Taking what was once considered waste streams and turning them into usable products for the construction materials industry is part of the vision of our company."
Saudi Arabia: Al Kifah Ready-Mix & Blocks (KRB) has announced the upcoming launch of its ConGreen reduced-CO2 concrete products range at the Big 5 Saudi construction summit on 28 – 31 March 2022. ConGreen concretes replace clinker with lower-carbon materials such as pozzolan and use Canada-based Carbon Cure Technologies’ embedded recycled CO2 technology to reduce its carbon footprint by up to 30% compared to conventional Ordinary Portland Cement (OPC) concretes. In addition to this, KRB says that ConGreen concretes also provide improved workability and pumpability properties, as well as being highly durable, with high passing and finishability. They have very low rapid chloride permeability (RCP), water absorption and water permeability properties and low heat of hydration.
General Manager Nigel Harries said “We are committed to driving energy efficiency and addressing the global emission challenges. We aim to help build a better community and environment-friendly facilities by producing high-quality concrete, such as ConGreen, that has a reduced environmental impact and is characterised by its high performance, durability and sustainability, with a low carbon footprint as compared with standard concrete.”
