UK: Hanson has been part of a new continuous concrete pour record in the UK as part of its work at the EDF Energy’s Hinkley Point C (HPC) new nuclear power station in Somerset. It supplied raw materials for the concrete to main civil engineering contractor BYLOR, which operates the on-site concrete production plant. The 9000m³, five-day, pour was to construct the last of five reinforced concrete segments that make up the cross-shaped foundations on which all of the first nuclear reactor’s buildings will sit. The record-breaking pour beats the previous UK record set by the Shard skyscraper in London.

The completion of the foundation platform, which is up to 4m thick, represents a significant milestone for the project, described by EDF Energy as J-zero. It marks the transition from below ground activity to the construction of permanent reactor buildings above ground.

Hanson says that mix design for HPC took three years of development and testing to ensure that the concrete was of the required quality mandated by the Office for Nuclear Regulation. The subsidiary of Germany’s HeidelbergCement has 65 employees directly involved in the HPC project team. To date Hanson has supplied 51,000m³ of concrete, 2.5Mt of aggregates, 210,000t of marine sand, 65,000t of cement; 105,000t of ground granulated blast furnace slag (GGBS) and 125,000t of asphalt.

India: Credit rating agency ICRA expects that cement demand growth will fall to 7% year-on-year in the first quarter of the 2019 – 2020 financial year from 13% in the previous year. It has blamed this on a slowdown in infrastructure projects due to the general election and resulting labour shortages. However, higher cement prices and lower input costs - including power, fuel and distribution expenses – are forecast to improve profits. Cement consumption is predicted to increase in the third quarter due to housing demand and pickup in infrastructure schemes.

The agency also said that around 18 – 20Mt/yr of cement production capacity would be added in the 2019 – 2020 year. This will be from a variety of integrated and grinding projects. This is below the projected demand growth of 24Mt/yr but overall sector production overcapacity is expected to continue at around 71%.

India: UltraTech Cement is in talks to buy a stake in Emami Cement for up to U$800m. Sources quoted by the Economic Times newspaper say that UltraTech Cement is working with private equity companies, including KKR and Temasek Holdings, on the potential deal. Emami Group is reportedly still deciding whether to sell its entire cement business, a stake or selected assets.

Emami Cement operates a 2.5Mt/yr integrated plant at Risda in Chhattisgarh and a 2.5Mt/yr grinding plant at Panagarh in West Bengal. It acquired a 0.6Mt/yr grinding plant at Bhabua, Bihar in September 2018. In addition, the firm has mining assets in Guntur in Andhra Pradesh and near Jaipur in Rajasthan. Its main markets are in West Bengal, Chhattisgarh, Odisha, Jharkhand, Bihar, Maharashtra and Madhya Pradesh. It markets its products under the Double Bull brand.

Cameroon: Ciments de l'Afrique (CIMAF) has agreed with the Cameroon Investment Promotion Agency (CIPA) to invest US$33m in its integrated plant at Douala. The subsidiary of Morocco’s Addoha Group plans to triple the plant’s production capacity to 1.5Mt/yr, according to Business in Cameroon magazine. The unit was originally commissioned in 2014.

US: Charah Solutions plans to open a grinding plant to make supplementary cementitious materials (SCM) from natural pozzolan at Oxnard in California. The unit will be accessible by truck and railway. It will sell pozzolan and other materials to concrete product manufacturers throughout south California.

The Oxnard plant will be operated in partnership with Diversified Minerals, a supplier and manufacturer of standard and custom blend cement and concrete products. It will receive natural pozzolan by truck and rail and then grind pozzolan marketed under the brand MultiPozz pozzolan. MultiPozz pozzolan will be distributed throughout Charah Solutions’ MultiSource materials network of more than 40 nationwide in the US with international sourcing and distribution.

“Fly ash is becoming more difficult to source in California, which is forcing the construction industry to look for viable alternatives. Natural pozzolan and other SCMs that meet ASTM specifications are generating very high interest. With Charah Solutions’ resources and DMI’s strategic partnership with the only active pozzolan mine in Southern California, we are both the closest and the first to bring these products to market,” said Jim Price, chief executive officer (CEO) of Diversified Minerals.
