supplementary cementitious materials

Concrete production is one of the largest consumers of natural non-metallic materials. To mitigate the environmental impact associated with cement production The use of wastepaper sludge ash (WSA) from paper recycling is a new promising direction for saving fuel, energy, and natural resources in cement and concrete production, aimed at reducing the proportion of clinker in cement by replacing part of the cement with supplementary cementitious materials.

One of the main tasks of building industry is to reduce carbon dioxide emissions, which are generated during the cement production, without losing the properties and quality of the binding agent.
