University of Tokyo researchers develop cement-free concrete production method from sand 21 April 2021
Japan: Researchers from the University of Tokyo have developed a new method for producing cement-free concrete from sand. The method reacts sand with alcohol in the presence of a catalyst, according to ChemEurope. When dehydrated, this produces tetraalkoxysilate. The research team then reintroduced water, and thus allowed the reactants to move back and forth between tetraalkoxysilate and sand. In this way, the sand particles progressively bonded together. The resulting concrete is reportedly more resilient to chemical, temperature and humidity changes than concrete produced from Ordinary Portland Cement (OPC).
In the report of the findings, researcher Ahmad Farahani wrote that various sources of sand tested suitable for use, including silica sand, glass beads and simulated moon sand. This gives the method the advantage that it is non-specific to raw materials or locations, and can be integrated into waste management.
GCCA expands Innovandi innovation programme 21 April 2021
UK: The Global Cement and Concrete Association (GCCA) has expanded its Innovandi innovation programme with the addition of a new Open Challenge innovation accelerator programme. The Open Challenge programme will bring together start-ups and leading cement and concrete producers to innovate for CO2 emissions reduction in the cement industry. Its aim is carbon neutral concrete production by 2050.
GCCA chief executive officer Dinah McLeod said “The GCCA is delighted to be expanding Innovandi to encompass both the Research Network and the upcoming Open Challenge. By connecting innovative start-ups with cement and concrete producers we can help accelerate the development of solutions that address the emissions reduction challenges our industry faces.”
Spain: Cementos Cosmos and the Cooperativa Apícola del Bierzo have installed 25 bee hives at the Corullón quarry, which supports the integrated Toral de los Vados plant in Leon. The collaboration agreement aims to promote the production of honey, propolis and pollen. The hives will be cared for by the Bierzo Beekeeping Cooperative and the adaptation and maintenance of the land where they will be located will be carried out by Cementos Cosmos. The cement company will also become the preferred customer for the production of the beehives located in the quarry. Following the signing of the agreement plant director Jaime Santoalla said, "we are convinced of the coexistence and synergies between our industry and other sectors of Bierzo, such as the agricultural-food sector.”
Bedeschi awarded contract for Port of Takoradi in Ghana 21 April 2021
Ghana: Italy-based Bedeschi has been awarded a contract to supply and install cargo handling equipment for the Port of Takoradi. The project includes the supply of handling equipment and services for importing clinker and exporting bauxite and manganese. Bedeschi will supply five conveyor belts with a total length of 3km, two type 50/1400 A frame shiploaders and one eco-hopper. The shiploaders and the eco-hopper will be delivered fully erected from the supplier’s shipyard directly to the client jetty with a dedicated heavy lift vessel.
The project will adhere to ‘state of the art’ environmental standards with the use of dust collection and de-dusting system specifically designed for this application. All the conveyors will be closed, included the section where tippers and eco hoppers are in operation. Bedeschi will also provide the computerised control system too. No value for the contract or date of commissioned has been released.
India: Road Transport and MSME Minister Nitin Gadkari says that ‘huge demand’ is being created for steel and cement companies due to the rapid construction of road infrastructure. However, he also accused the industries of creating cartels and exploiting people, according to the Press Trust of India. The minister said that the government is now looking for some alternative for steel and cement. At a webinar Gadkari said that road construction has reached 37km/day day.
US: Australia-based Boral Limited says that as part of the review of its North American Fly Ash business, it is considering options such as a potential joint venture, a strategic alliance, divestment to a third-party or continued ownership. Boral has appointed advisors to support an assessment and intends to release an update by August 2021 or earlier if appropriate.
“We have conducted a detailed study of the US fly ash industry and remain confident in the long term demand dynamics for the industry, including significant incremental demand growth potential from the US Government’s proposed new infrastructure program,” said Boral’s chief executive officer and managing director Zlatko Todorcevski. “New opportunities for supply exist from harvesting landfills, imports and natural pozzolans, which we expect will more than offset the decline in fresh fly ash supply as the US transitions away from coal fired power generation.”

CarbonBuilt and CarbonCure Technologies win carbon capture and storage design competition 20 April 2021
US/Canada: XPrize has named CarbonBuilt and CarbonCure Technologies as the winners of carbon capture and storage (CCS) design prizes worth US$20.0m. The competition ran at two power plants in Wyoming, US and Alberta, Canada. CarbonBuilt won the contest at the Wyoming plant with a concrete-curing based system. The concrete produced has a lower carbon footprint than conventionally produced concrete, according to XPrize. CarbonCure Technologies won the Alberta contest with a design based on carbonating the water used in washing cement trucks. This reportedly formed a concrete-strengthening slurry.
XPrize has partnered with Elon Musk and the Musk Foundation to launch a second round of CCS design prizes worth a total US$100m.
