Kenya: East African Portland Cement Company (EAPCC) has announced plans to build a new clinker plant in Kajaido. The Nation newspaper has reported that it will cost US$200m to build. EAPCC plans to use local pozzolana, along with limestone and coral transported from Kenya’s Coast Province, in cement production at the plant. The producer says that it will clarify the timeframes of the project in 2024.
SRMPR Cements launches Portland pozzolana cement
02 November 2023India: SRMPR Cements has launched its Portland pozzolana cement (PPC) for the first time, in Tamil Nadu. The Hindu BusinessLine newspaper has reported that the company controls 420,000t/yr of cement production capacity across three facilities in Tamil Nadu and neighbouring Andhra Pradesh. It invested a total US$27m in its production facilities and warehouses. SRMPR Cements will sell its PPC in 50kg bags. It also plans to launch ordinary Portland cement (OPC) in the future. It said that its products will help to meet ‘massive’ demand from public construction projects.
CEO Ohm Prakash said that the producer has already concluded deals with 100 different regional retailers of cement.
Solidia Technologies patents new synthetic pozzolan
11 September 2023US: Texas-based Solidia Technologies has patented a synthetic pozzolan that may be used as a supplementary cementitious material (SCM) in cement production. The product is based on previously low-value materials, including minimally processed oil shales and clay minerals. Solidia Technologies produces the material by various methods, including firing the materials to yield a mix of crystalline components and activatable amorphous phase material. Alternatively, production may also involve the aqueous decomposition of manmade silicates in the presence of CO2.
Spain: Residents of Cartagena, Murcia, have protested Cemex’s plans to begin mining pozzolan at new sites locally. The Murcia Plaza newspaper has reported that the protestors are calling for a mining ban, in line with their interpretation of the area’s Rural Area of Special Environmental and Social Sensitivity designation.
Neocrete plans first Neocrete activator plant
24 July 2023New Zealand: Neocrete has launched an investment round to raise over US$1.86m in funding. The start-up will use the funds to build an industrial-scale plant for its Neocrete activator for pozzolan-based concrete. The use of Neocrete's activator can eliminate up to 50% of cement in concrete. Neocrete aims to ultimately displace 100% of concrete's cement content. The Hawke's Bay Today newspaper has reported that pozzolan-based concrete made using Neocrete's additive offers resilience benefits compared to conventional ordinary Portland cement (OPC)-based concrete. It is especially suited construction in seawater-exposed settings.
Germany: Dyckerhoff has launched Dyckerhoff Weiss Blue Star, a pozzolanic white cement CEM IV/A (P) 42.5 R product. It was approved by the German cement association, the VDZ, in mid-June 2023 and is now being manufactured at the Amöneburg plant. The lower CO2 credentials of the new product have been promoted as it releases around 15% less CO2 compared to CEM I cements. It is also notable for being a blended white cement.
Cem'In'Eu launches FUSIOCIM 43% reduced-CO2 cement
13 July 2023France: Cem'In'Eu has launched FUSIOCIM, a CEM II/C pozzolan cement, that offers a 43% reduction in CO2 emissions compared with ordinary Portland cement (OPC). FUSIOCIM has specific CO2 emissions of 506kg/t. It is suitable for various concrete applications and comes in 25kg bags.
Cem’In’Eu general manager Fabien Charbonnel said "We created Cem’In’Eu with the ambition of reducing the carbon footprint of the cement industry. And we are proving it today with a low-carbon offer that easily replaces traditional cements, without any change for construction professionals. We are convinced that this transition can only be done with pragmatism and taking into account the needs of users.”

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.”
Cimpor signs pozzolan deal in Cape Verde
10 May 2023Cape Verde: Portugal-based Cimpor has signed a deal with the government of Cape Verde to develop and exploit a pozzolan deposit over the next 30 years. Exploration of the site is expected to begin by late 2024. The immediate location has reserves of around 0.5Mt in an area of 108 hectares. However, the scheme also has the option to expand the site to 790 hectares, increasing the estimated pozzolan reserves to 4Mt. The project has an investment of Euro3m and is expected to create around 80 jobs.
Cimpor’s parent company OYAK Cement previously said in 2019 that it was planning to invest in pozzolan extraction in Cape Verde.
Progressive Planet to supply PozGlass to Lafarge Canada
16 March 2023Canada: Progressive Planet has secured a contract to supply its PozGlass recycled glass-based supplementary cementitious material (SCM) to Lafarge Canada. The cement producer says that it will test the commercial viability of all PozGlass produced at Progressive Planet's Kamloops pilot plant in British Columbia, once the plant commences PozGlass production in 2024.
