US: Solidia Technologies has filed a patent for a new hydraulic cement consisting of Ordinary Portland Cement (OPC) and other supplementary cementitious materials (SCM) including lime, alkali hydroxides, clay minerals and over 10% synthetic pozzolan.

Solidia Technologies said, “In order to reduce global CO₂ emissions it is necessary to adopt new approaches to create a new generation of hydraulic cements. The most efficient cement kiln can produce OPC clinker with an associated emission of 816 kg of CO₂/t. Blending the ground cement clinker with SCM, which have low or zero associated production CO2 emissions, reduces the total embodied CO₂ of the final product. Using a cement with the lowest possible clinker factor for a given application is the most common industry approach to reducing the CO₂ footprint of concrete.”

Finland: Lujabetoni says it has begun work on a new 80 - 100m3/hr ready-mix concrete plant in Kuopio, Northern Savonia to replace its existing plant in the town. The new unit, which will serve construction projects throughout the region, will have an improved raw materials heating system. The plant is scheduled for completion in late 2020 or early 2021.

Kazakhstan: Steppe Cement recorded earnings before interest, taxation, depreciation and amortisation (EBITDA) of US$23.9m in 2019, up by 12% year-on-year from US$21.4m in 2018. Sales volumes of cement remained stable at 1.7Mt with local sales increasing by 4% and exports decreasing by 29% due to increased competition and negative currency effects. Steppe Cement said that overall domestic demand was 8.9Mt, up by 2% from 8.7Mt in 2018. The company operated at 88% production capacity and production costs per tonne rose by 10% due to increases in fuel and transportation prices.

Nigeria: Sinoma Construction Nigeria says it has completed the construction of a second 6000t/d line at BUA Group subsidiary Obu & Edo Cement’s Edo cement plant, bringing the plant’s total integrated capacity to 5.5Mt/yr. The subsidiary of China-based Sinoma said that it completed the work in spite of an outbreak of malaria and electricity shortages. It said, “The successful fulfilment of the project has laid a solid foundation for the company's in-depth localised operation and comprehensive cooperation with the BUA Group.”
