“…Used in particular applications (stiff, extruded or sprayed concrete, usage of high amount of slag), hollow microspheres or microfibers, which are deformable solid elements can replace the 4-8% entrained air to ensure good durability of concrete under freeze-thaw cycles, without jeopardising the mechanical performance. These microspheres are extremely small, hollow, highly resilient, tough but flexible, with acrylonitrile polymeric shells, providing stress relief zones for the expansion of freezing water within concrete and enhancing its long-term durability [115]. But, in order to try to generalise their use, research is needed to significantly reduce their dosage (3-7 kg/m³) and cost.…”

The needs for research on cementitious materials are reviewed with a focus on Europe. These are considered under 8 topics: clinker production, alternatives to Portland cement, composite cements based on Portland clinker, concrete, admixtures, durability, recycling, digitisation in concrete construction, and, carbon capture and use or storage; finally, the key research questions and their potential for CO2 reduction are summarised in a “Watermelon” diagram with a list of 30 key questions to be addressed (see Appendix).
