Mexico/Denmark: Cemex and 3D printing construction company Cobod International have launched D.fab, a range of admixtures which enable builders to use ordinary concrete in 3D printing. The partners say that the products eliminate the need for expensive specialised mortars. Power2Build implemented the admixtures in concrete to print a whole house in Luanda, Angola, in early December 2021.

Cemex’s executive vice president sustainability, commercial and operations development Juan Romero said “The introduction of this revolutionary 3D printing system is a testament to our customer-centric mindset and relentless focus on continuous innovation and improvement. Working together with Cobod, we have developed an experience for customers that is superior to anything that has been provided in the past,” said “Our innovation efforts position us at the forefront of new technologies that contribute to building a better future.”

Pakistan: BHS-Sonthofen (Tianjan) has reported the successful delivery of two of a total of six twin-shaft batch mixers to the site of CEC-PowerChina and Pakistan Frontier Works’ upcoming Diamer-Basha dam. The Chinese division of the Germany-based company is supplying four DKX 7.00 7m³/batch precast concrete mixers and two DKX 6.00 6m³/batch precast concrete mixers as part of the project. The mixers will contribute towards the 18.6Mm³ of mainly roller-compacted concrete required for the dam’s construction.

General manager Ronny Laux said “The hydraulically bound base layers required for the dam (also known as roller-compacted concrete) must withstand the heaviest of loads. Our mixers are designed to handle demanding mixing tasks. The twin-shaft batch mixers meet the highest demands for mix homogeneity and reproducibility, even with large quantities – ensuring optimum concrete quality.”

Algeria: BMSD Chaux Algeria has commissioned a 100,000t/yr lime plant. Italy-based QualiCal supplied the plant. It is powered by natural gas and relies on CogiTech bulkmaterial handling equipment, Mathios Refractories’ refractories, Laife steel structures and Sysware and Tecnoelettra automation systems.

Taiwan: Asia Cement Corporation plans to establish further offshore wind power plants under an extension of its partnership with Germany-based power company RWE. SNL Energy Finance Daily News has reported that the partners are investigating potential sites in Changhua, Hsinchu and Taichung.

UK: Tarmac has supplied its Toptint Glow glow-in-the-dark concrete for a major mixed-use commercial development called The Glass Yard in Chesterfield, Derbyshire. Construction company Blue Deer used Toptint Glow in the main walkways and first-floor balconies of the office, restaurant and retail complex. France-based Chryso supplied its Lumintech glow-in-the-dark chippings for use in the concrete. The supplier said that the chippings are fully recycled. They are available in white, stone, light grey, agate and jade to match the colour of the concrete mix. Each has a corresponding glow colour of blue, green turquoise or blue turquoise. Tarmac says that glow-in-the-dark concrete helps to enhance the nighttime built environment.

Product development manager Glanville Norman said “Tarmac is always looking to develop new and exciting materials that can complement bold design. This is the first time that Toptint Glow has been used on a major commercial development and we were delighted to be able to propose a solution that not only has high aesthetic and environmental quality but also helped to improve safety and visibility.”

US: Cementos Argos plans to begin trading publically in mid-late 2022 with the launch of an initial public offering (IPO) on the New York Stock Exchange.

China: China has increased its production of cement by 2.1% year-on-year to 1.97Bnt in the first 10 months of 2021. Xinhua’s China Economic Information Service has reported that the country exported US$19.6bn-worth of building materials over the period, up by 13%, while its domestic construction market grew by 11%.

UK: Construction company Milestone Infrastructure used cement-free concrete supplied by DB Group subsidiary Cemfree to lay kerbs for a new road in Cambridge, Cambridgeshire. The work consisted of a road widening in order to create new cycle and bus lanes with floating bus stops and an innovative cycle roundabout. Milestone Infrastructure built 13,000m² of new paths and cycle lanes, diverted 74 underground utilities and resurfaced 18,000m² of road. The project begun in February 2020.

Switzerland: Holcim has launched the DYNAMax range of high-performance concretes. The producer says that the range offers higher compressive strength, rigidity and durability than its other concrete products. In 2022, it plans to begin marketing DYNAMax in ten markets in its Asia Pacific, Europe, Latin America and North America regions.

Chief executive officer Jan Jenisch said “I’m excited by the launch of our DYNAMax high-performance concrete, advancing our global range of innovative and sustainable building solutions. With today’s population and urbanisation trends, DYNAMax is an ideal material to build smarter cities. It offers high performance to build more with less with no compromise on aesthetics and functionality.”

South Korea: Researchers at Incheon National University have discovered an optimal conductive carbon fibre volume for cement-based conductive composites for use in net-zero energy buildings. The team reported that a 1% conductive carbon fibre content facilitates maximum energy generation from the movements of occupants and the weather against floors and walls. It also enables the storage of electricity at safe voltages. The product is based on triboelectric nanogenerator (TENG) technology.

The team published its results in the journal Nano Energy in November 2021.
