Recycling solid waste to produce eco-friendly ultra-high

1 Ahmad et al. used natural pozzolan to replace part of the cement or microsilica and found that the drying shrinkage of UHPC was improved. This was mainly attributed to the potential pozzolanic reaction that refined the pore structure and hindered water evaporation (Ahmad et al., 2019). (UHPC) with efficient cement and mineral
