Blast furnace slag has been used as an aggregate in concrete for around 100 years. They replace natural rock and contribute to resource conservation and the circular economy as well as securing the supply of raw materials for the concrete industry.

Greater climate friendliness is one of the most ambitious goals of the energy-intensive cement and lime industry. Aerzen's turbo technology supports the cement and lime industry on the path to climate neutrality.

Since oleochemical products are based on vegetable and animal fatty acids, they are not only used for their effectiveness but also for sustainability reasons. Common oleochemical hydrophobing agents include metal and alkaline soaps.

Whether in the cement or chemical industry, from an environmental or legal point of view, politically or socially – the major goal of CO2 neutrality can only be achieved as a closed unit.

One of the world’s first climate-neutral cement plants is taking shape: Vice Chancellor and Federal Minister of Economics Dr Robert Habeck and Holcim Germany CEO Thorsten Hahn, broke ground on the “Carbon2Business” innovation project in Lägerdorf.

Carbon Capture & Utilisation (CCU) enables the substitution of fossil carbon in sectors where carbon is necessary. Dioxycle, D-CRBN and Twelve showcase winning solutions that pave the path for a renewable carbon society.

Hydrated lime is in the trend, because it can save resources and provide better CO2 reduction potentials than any other lime product.

The capture of CO₂ and its subsequent use and storage are key elements of the cement industry‘s decarbonisation strategy. The separation of CO₂ from waste gas is an energy-intensive and complex...

This report describes systematic measurements of the velocity ratio C = uS/uF in a vertical pneumatic conveyor line. Two limestone fractions of the same base material were analysed, which had mean...

In this paper, the effects of styrene-butadiene rubber (SBR, 1%~4%) powder on the autogenous shrinkage and compressive strength of cement-based materials at 3, 7, 28, 60 and 90 d were firstly studied,...
