Kiran Global launches environment-friendly cement

Written by Global Slag Staff
28 January 2016

India: Kiran Global Chems has launched Geocement, an environmentally-friendly branded cement. The company claims that the product is stronger than Ordinary Portland Cement and that it does not require water for mixing or curing, according to local media.

Geocement is made from Geopowder and Geobinder, other products also made by Kiran Global Chems. Geopowder uses industrial by-products such as fly ash, rice husk ash, slag, activated clay and alumina. At construction sites it can be mixed with the company's proprietary Geobinder liquid and aggregates to make concrete. The company claims that Geocement does not require water curing and attains maximum strength within seven hours. Kiran Global Chems has also launched Geocrete, a Geocement concrete made with its powder and binder for various industrial applications.

"We have started distributing this to the bulk customers, such as builders and now we are launching the brand for retail. We are planning to sell it through e-commerce," said M S Jain, chairman of Kiran Global Chems. The price of Geocement will be slightly higher than normal cement, but it promises lower finished building cost and less construction time and labour. The company intends to target southern Indian states in 2016.

Kiran Global is also preparing a US$29m expansion programme to set up 12 Geobinder units, 12 Geopowder plants, two precast concrete units and four grinding units across the country. The expansion, is intended to cut logistics cost, will result in 4Mt of capacity with a potential turnover of up to US$300m by the 2018 – 2019 financial year. The company has an in-house research and development centre, accredited by the Union Ministry of Science and Technology, and has been conducting geopolymer research in collaboration with leading research institutes.

JFE Steel slag to be used in Hiroshima port project

Written by Global Slag Staff
11 December 2015

Japan: JFE Steel Corporation will use its steelmaking slag product Marine Stone in an environmental improvement project by Hiroshima Prefecture. Around 38,000t will be laid under the inner harbour of Fukuyama Port in Fukuyama-shi, Hiroshima. The sediment improvement agent is expected to control the generation of hydrogen sulphide.

Ferrous slag market forecast to rise by 1.6% to 2025

Written by Global Slag staff
04 December 2015

World: The ferrous slag market in 2014 was worth an estimated US$30bn. It is forecast to grow by 1.6% to US$36bn by 2025, according to a new report from Smithers Apex.

'The Future of Ferrous Slag to 2025' examines the factors affecting ferrous slag production to provide a basis for forecasting the quantities likely to be produced up to the year 2025. It looks at current and possible future applications of slag and describes the trends in regulations affecting the market.

The current potential market supply of blast furnace slag is estimated to be 447Mt, of which almost 295 – 300Mt is granulated blast furnace slag (GBS). The making of steel from blast furnace iron through oxygen conversion (or basic oxygen furnace, BOF) contributes a further 140 – 145Mt of slag and the alternative route to steelmaking through electric arc furnaces (EAF) supplies more than 50Mt.

According to the report, the total output of ferrous slag is expected to increase only slowly, or to stagnate and decline marginally, because EAF steelmaking capacity is expected to grow faster than BF-BOF steelmaking capacity. This effect can already be seen in the US, where the tonnage of steel produced by EAF plants overtook the tonnage produced by BF-BOF plants in the 1990s. Since then, further decline in BF-BOF output has led US-cement and aggregate companies to start importing slag and to invest in new coastal slag treatment installations dependent entirely on imported supplies.

Changes in the Chinese steel industry will contribute substantially to this rising share of EAF steel in world supply. China produces half of world crude steel and BF-BOF steelworks account for over 80% of China's steel output. The Chinese government is campaigning to replace small and inefficient steelworks with EAF installations.

In the current market, it is estimated that total production of ferrous slag of all types amounts to US$24.5bn. While it is possible that supply will increase only slowly, if at all, there is growing demand for slag products, which is likely to ensure that the value per tonne of slag products will increase. The growth in demand has been accelerated by environmental legislation and by direct intervention from governments and international bodies.

Demand for slag products has been affected by market cycles. The collapse of construction activity in Europe, as a consequence of the financial crisis, reduced sales of slag for cement and aggregate use. Over the medium term, there is every prospect that demand will outrun supply. Currently GGBS meets only an estimated 17% of global cement supply. Slag products as aggregate substitutes meet only 1 - 1.5% of total demand.

South Africa: Evraz Highveld Steel and Vanadium has announced plans to oppose court action by some of its major creditors, which want to declare the company's business rescue as invalid.

The company, which makes flat steel products, structural steel and vanadium slag, said that it has filed a notice of intention to oppose the further urgent court proceedings that East Metals and Mastercroft instituted against the joint business rescue practitioners of Evraz Highveld Steel and Vanadium and several other affected persons.

BMR Mining identifies new market for slag at Zambia Tailings plant

Written by Global Slag staff
09 October 2015

Zambia: BMR Mining has identified a new market for Waelz Kiln slag at its operations in Kabwe, Zambia. The ferro-silicate zinc slag can be used for the construction of building blocks. BMR has produced a test batch of building blocks, using an 80:20 ratio of slag to building sand, which has not resulted in the leaching of either lead or zinc.

BMR will submit an application for approval from Zambia's Environmental Management Agency (ZEMA) to produce the slag for building and concrete production. The company is submitting an Environmental Project Brief, which is less complex than approval for an Environmental Impact Study. The application will be submitted in November 2015 and is expected to be approved by the end of 2015.

Once the company has received approval, BMR aims to sell the slag locally to limit costs. "We therefore anticipate BMR generating revenue in 2016, following receipt of ZEMA approval, from both the processing of Wash Plant Tailings and the Waelz Kiln Slag," said BMR Chairman and CEO Alex Borrelli. BMR assets in Zambia include the Chingola Tailings, Kabwe Tailings and Ndola projects.
