Scientists at the Institute of Chemistry of the Academy of Sciences of Turkmenistan have developed a technology for producing Portland cement with an increased content of mineral additives, which reduces the environmental impact without compromising quality. This was reported by the IIC of Turkmenistan.

According to Rejepnur Nurberdiyev, Head of the industrial chemistry laboratory, the main cause of emissions in the cement industry is clinker production. Scientists have proposed increasing the proportion of active mineral components from 20% to 35%, reducing clinker and fuel consumption.

Local moulding sand with active silicon oxide is used as an additive. Tests have shown that the cement retains its strength and resistance to aggressive environments, while reducing emissions and gas consumption. More than 300 kg of clinker is saved per tonne of cement.

The results have been published in an international scientific journal and confirmed by joint research with the State Energy Institute of Turkmenistan.

There are five cement plants in the country with a total capacity of over 3.5 million tonnes per year. The introduction of the new technology will increase the energy efficiency of the industry and its compliance with the principles of the ‘green’ economy.
