Universities research rice husk ash as cement alternative09 July 2024, Published under Cement NewsResearchers from ten universities across the globe are exploring the feasibility of using rice husk ash (RHA) in place of cement for manufacturing activities. The participating researchers have found the RHA has a high silica content. Therefore, when RHA is used to produce concrete, it triggers a chemical reaction with hydrates (such as calcium hydroxides). This results in the formation of supplementary products that give the mixture strength and stability, which are vital for the concr... |

Improving ash quality01 February 2016, Published under Cement NewsAs governments consider the reduction of power generation in coal-fired power stations for environmental reasons, this article looks at the impact of this measure on the supply of fly ash to the cement industry. However, in the short- to medium term the availability of fly ash seems to be robust as sufficient stocks appear present, either in landfills or in fly ash lagoons. Coal-fired power stations have long supplied fly ash to cement plants as an addition to Portland cement As... |
Cement plants of the future18 November 2013, Published under Cement NewsIn the first of a series of articles for ICR, Kline Consulting explores the impact that reducing carbon emissions could have on the design of cement plants of the future. The three traditional CO2 reduction levers – namely energy efficiency (fuel and power), fuel CO2 reduction and clinker substitution – will all be considered in detail, as will the role of carbon capture technologies. In this first article, the author focusses on clinker substitution and the changes that may be required to e... |
