UK: A study by the University of Dundee has dispelled the myths of substantial performance differences between concretes made with cement containing dry or wet-stored fly ash, with comparable reinforcement corrosion between the two.

Vertical News has reported that the research, whose backers included the Department for Environment, Food & Rural Affairs and Heathrow Airport Holdings, was aimed at “quantifying moisture effects, which indicate agglomeration of fly ash and a tendency for this to increase with free lime content, storage period and temperature.”

Researchers tested five moistened fly ashes and samples from two power station stockpiles, and further investigated different material and storage variables, comparing the concretes at 75mm slump and 28 day strength. Air permeability and water absorption of moistened fly ash proved greater with high free lime (up to 0.9%) and lower with low free lime (to under 0.1%). What benefits there were improved with longer storage. The moistening of low-free-lime fly ash generally yielded similar, or slightly higher, carbonation and chlorine diffusion. The moisture caused little change in high-free-lime ash’s carbonation, while increasing chloride diffusion. Furthermore, high storage temperature equated to greater carbonation.

In spite of these intriguing chemical differences, the study concluded, "these didn't seem to have a noticeable effect on concrete resistance.”

India: Ramco Cement is set to complete its expansion works, aimed at raising total production capacity to 20Mt/yr from 12.5Mt/yr, by the end of 2020.

Ramco’s capacity utilisation in the three months to 30 June 2019 was 90%, 23% above the national average of 67%. ProjectsToday reports that the company is investing US$467m in developments, including a US$347m grinding plant in Arunachal Pradesh.

The company reported net profits of US$26.7m in the quarter to 30 June 2019, up by 53.6% from US$17.3m in the same period of 2018, against a backdrop of a struggling domestic market, with national cement sales in July down by 2.8% to 3.6Mt from 3.5Mt a year ago.

China: DongWu Cement’s net profit over the six months to 30 June 2019 was US$4.83bn, up by 20.6% from US$4.00bn over the same period of 2018. Its cement segment reported a net profit of US$5.37bn, up by 9.1% from US$4.92bn in the corresponding period of 2018.

In its financial statement, DongWu noted a year-on-year growth in China’s total cement output of 6.8% to 1.05Bnt in the first half of 2019, with prices also increasing by 4.1% to US$60.9/t, though growth rates have slowed.

Infrastructure developments have driven swelling demand, while compressed supply has brought the centrally organised economy’s cement reserves to a medium-low level.

Uzbekistan: Uzbekistan’s cement imports totalled US$105.6m over the six months to 30 June 2019, up by 32.3% from 2018.

Chinese investment in Uzbek domestic cement production saw two cement plants of 1.2Mt/yr and 2.4Mt/yr capacity enter development in 2018. Huaxin Cement’s Zafarabad plant is expected to become operational in December 2019, with Gansu Hengya Cement’s Kattakurgan plant also due to enter operation in the coming months.

Malaysia: YTL’s net profit in the quarter ended 30 June 2019 was US$0.58m, compared to a net loss of US$15.1m in the same quarter of 2018, as its cement section’s profits before tax grew to US$3.02m, up by 20.0% compared to the same period of 2018, as it benefitted from the higher profit share of its associates.

Ivory Coast: LafargeHolcim has constructed a depot in Bouaké, the second city of Ivory Coast, for storage of cement produced at its facility in the capital of Abidjan.

In a press release sent to the Agence Ivoirienne de Presse, LafargeHolcim explained that the aim of the development is to bring consumers and its supply closer together. It hopes thereby to maximise the national presence of it 2Mt/yr cement plant.

Russia: Eurocement has invested US$2.26m in upgrades to its Pikalevsky cement plant in the Leningrad region.

Eurocement has reported that tests have proven a 27% decrease in the water separation rate and an increase in the rate of curing of Pikalevsky’s cement following the upgrade. Strength indicators showed a 20% improvement in performance to 25MPa after three days, and over 60MPa after 28 days. Setting start time also increased to 175 minutes. Eurocement’s solution for particle size distribution in clinker after grinding has caused a notable boost in durability indicators.

Representatives of KHD, Aumund and Siemens aided in the installation and instruction of plant employees in the use of the new grinding technologies.

UK: Aggregate Industries has released a range of admixture-driven waterproofing solutions, blended with a custom mixes of BASF’s MasterLife WP 799, called Watertight^TM concrete.

Aggregate industries has described the high performance integrated waterproofing systems as ‘insensitive to weather, groundwater and sprinkler systems.’

US: Nano Graphene has launched a concrete admixture. OG Concrete Admix improves concrete’s water resistance by a factor of four and more than doubles the strength, while significantly reducing cracking.

In GrapheneCA’s promotional material, it mentions a lowered carbon footprint amongst the benefits of its admixture for concrete producers, with less cement being required in the production of concrete using OG Concrete Admix.

Malaysia: Cahya Mata Sarawak (CMS)’s cement division has reported a net profit of US$19.5m in the six months to 30 June 2019, down by 37.1% from US$31.0m in the same period of 2018. The company’s total first half revenue rose by 8.9% to US$194m from US$178m in 2018.

In its financial statement, CMS blamed the cement profit slump on rising clinker import prices and the cost of fuel for its coal-fired cement plants. CEO Datuk Isaac Lugun has expressed hope for the group’s longer-term prospects due to its competitive power pricing and strong global presence.
