Eco-friendly ultra-high performance cement pastes produced with quarry wastes as alternative fillers

About 35 billion tons of quarried material are produced annually throughout the world, generating large amounts of waste powders which are usually disposed of in landfills. This work investigated the feasibility of producing eco-friendly ultra-high performance cement pastes with diabase, granite and basalt quarry wastes as alternatives to quartz and limestone conventional fillers. The fresh properties (rheometry and mini slump), hydration...
