Morocco: Members of the Professional Association of Cement Producers (APC) delivered a total of 6.98Mt of cement during the first seven months of 2023. This corresponds to a year-on-year rise of 2.1%, compared with seven-month 2022 levels. Agence Marocaine de Presse News has reported that ready-mix concrete plants consumed 4.29Mt (61%), and precast concrete plants 1.37Mt (20%), of cement deliveries. Producers despatched 367,000t (5.3%) of cement to infrastructure construction sites, and 271,000t (3.9%) to other building sites.
India: Ramco Cements has commissioned a 3000t/day integrated cement line at its Ramamasamy Raja Nagar cement plant in Tamil Nadu. Projects Today News has reported that the plant runs on renewable energy from a captive wind farm, and recycles 90% of water used in production.
Ramco Cements produces Ramco 53 Infra Super cement at the Ramamasamy Raja Nagar plant. The product allows for lower cement and admixture content to be used in the production of concrete structures.
Finland: VTT Technical Research Centre subsidiary Carbonaide has concluded its seed funding round, having raised funds worth Euro1.8m. Lakan Betoni, which produces precast and ready-mix concrete, led the funding, along with utilities provider Vantaa Energy. Carbonaide will use the funds to build an industrial pilot plant for its carbon neutral precast concrete product at an existing precast concrete plant in Hollola. The plant will bind captured CO2 in the product at atmospheric pressure. The process generates 50% lower CO2 emissions than precast concrete production using ordinary Portland cement (OPC). Suitable raw materials include ground granulated blast furnace slag (GGBFS), green liquor dregs and bio-ash. In trial production, the use of GGBFS gave Carbonaide's concrete a negative carbon footprint of -60kg/m3.
Other sources of loans and in-kind contributions included Finnish state innovation fund Business Finland.
Cement helps in destruction of seized cocaine
12 January 2023Ecuador: Encapsulation in concrete served to destroy 110t of cocaine in Ecuador during the first nine months of 2022. The figure corresponds to 61% of cocaine seized by authorities during the period. Local press reported that the mixed slurry forms strong precast concrete elements, from which the cocaine is impossible to extract. Encapsulation accelerates destruction of the drug by a factor of 20 compared to incineration, with removal rates of up to 1500kg/hr.
Ecuadorian cocaine seizures at ports alone increased by 42% year-on-year throughout 2022, necessitating the operational improvements in disposal methods.
Southeast University develops coral-based concrete
12 December 2022China: A team at Southeast University has developed an alternative concrete that contains 8% cement. It uses coral reef limestone fragments and biodebris with an upper particle size of 53mm as fine aggregate. The researchers concluded that the material proved suitable for use in precast concrete paving slab production.
Costa Rica: Holcim Costa Rica has acquired the heavy precast unit of Productos de Concreto for US$3.35m. The La Nación newspaper has reported that the company also increased its stake in prefabricated construction company Tecnología de Construcción to 100% from 49%. The latter deal's value was US$774,000.
Holcim Costa Rica's corporate affairs manager José Alfredo Alpízar Guzmán said that these latest acquisitions complement the producer's existing abilities to supply its customers.
Betolar launches Geoprime concrete products in India
11 October 2022India: Finland-based Betolar has launched its first concrete products manufactured using Geoprime on the Indian market. Geoprime is an additive designed for use in cement-free concrete production with ash and ground granulated blast furnace slag (GGBFS). The new concrete product range consists of precast blocks, paving slabs and tiles, and is currently on display at World of Concrete India in Mumbai, Maharashtra.
Betolar's India managing director Abhishek Bhattacharya said "We are happy to introduce our first products to our customers for the Indian markets. We have now moved from laboratory tests into the production phase, and can show concretely how well this solution works. It is great to hear the feedback from the concrete industry in the region to our sustainable solution. Decarbonisation of the concrete industry is a very current and important topic."
France: Sustainable concrete producer Materrup has shared plans for its upcoming Bordeaux precast concrete elements plant. The L’Usine Nouvelle newspaper has reported that the facility will produce precast elements from Materrup’s cement-free concrete, which it produces from uncalcined clay, an activator and a precursor at room temperature. The technology, called Clay Cement 1 (MCC1), reduces CO2 emissions by 50 – 80% compared to ordinary Portland cement (OPC), according to the producer. It previously opened a Euro7m 50,000t/yr plant in the Atlantisub Business Area in Saint-Geours-de-Maremne, Nouvelle-Aquitaine.
India: The India Cements has launched Concrete Super King, a general application cement, and Halo Super King, a cement exclusively developed for use in the production of precast hollow dense concrete blocks.
Vice chair and managing director Narayanaswami Srinivasan said that many of the company’s customers already rely on its products in their precast hollow dense concrete block production. With the launch of Halo Super King, it hopes to further increase the ease of application.
