With 20 billion tons put to use every year, concrete is the most widely used building material in the world. Additives can be added to building materials, like cement mixtures, to ensure quality standards are maintained and the concrete produced is fit for its purpose. Evonik’s alumina additive, AP-22, modifies the viscosity of cement formulations and acts as an anti-shrinkage agent during the curing process.
