Increased competition, challenges facing S African cement sector

Published: 07 Jun 24

Cement producer Sephaku Cement notes that, over the last 20 years the cement industry has evolved and fragmented, which has, in part, resulted in challenges related to ineffective enforcement of regulation and quality standards, and excess capacity, in addition to the relatively new challenges of the carbon tax. The company explains that the cement industry has evolved from four integrated producers, which produced about 16 different cement types and/or brands, to six integrated producers, 11 cement blenders and five or six importers.

Cost-effective corrosion technology excels in harsh climates

Published: 07 Jun 24

Corrosion control specialist Cortec’s migrating corrosion inhibitors (MCIs) technology offers a cost-effective solution to extend structural service life in high-temperature areas, such as those in Gulf Cooperation Council (GCC) countries, says Cortec public relations manager Ana Juraga. The high temperatures and harsh conditions in such countries accelerate corrosion, threatening the durability of reinforced concrete, with corrosion activity doubling with every 10 °C rise in temperature.
