South Africa: Research carried out by Beton-Lab on the instigation off PPC has revealed a widespread flouting of cement quality regulations, with the majority of samples overweight or underweight and of inconsistent quality. Beton-Lab tested 14 products from 10 different producers. Cape Times has suggested that the results are due to the addition of fly ash and slag to finished cement as a common practice amongst producers.
In August 2019, PPC and other South African producers lobbied the government International Trade Administration Commission for a tightening of cement standards in response to a perceived compromise on quality by importers, whose 4.6% stake in the market grew by 293% year-on-year in July 2019.
