Special Issue Information
Dear Colleagues,
Recently, CO2 emission reduction, as well as building waste reduction and recycling, have been key topics for legislative bodies around the globe. In addition to these issues, new restrictions have been imposed. As the construction industry is one of the most polluting industries, the restrictions, which mostly refer to CO2 reduction of the construction material manufacturing and building processes, have given rise to the need for optimized construction materials and optimized building processes in order to achieve or come close to achieving this goal. As concrete and other cementitious composites are the backbone of modern civil and industrial infrastructures, there is no way to reduce CO2 by abandoning cementitious material usage altogether. Nevertheless, one proposed way is to optimize cementitious material design and to incorporate construction and building waste into the construction materials and their compositions.
Therefore, the goal for this Special Issue of Materials is to attract original contributions, with topics related to the latest developments in sustainable and innovative cementitious materials, as well as their design and property assessments.

Abstract: The flowability and mechanical properties are becoming increasingly crucial in the filling process of deep metal mines with mining depths exceeding 1000 m. The rheological properties of filling slurry in the pipeline were analyzed through rheological tests, L-tube self-flow tests, and semi-industrial loop tests. The results indicated that as the cement to tailings mass ratio (c/t ratio) and mass concentration increased, the slurry flow resistance increased, and the stowing gradient decreased. During slurry transportation, the pressure loss in the straight pipe is positively correlated with the slurry flow rate, c/t ratio, and mass concentration. The uniaxial compressive strength (UCS) test was conducted to analyze the macroscopic mechanical properties of the cemented paste backfill containing BMC (CCPB) in standard and underground deep curing environments. The UCS of the CCPB demonstrates an increasing trend with the rise in curing age, mass concentration, and the c/t ratio. The comprehensive analysis concluded that when the c/t ratio is 1:4, and the mass concentration is approximately 74%, the parameters such as slump, bleeding rate, and flowability of the filling slurry meet the criteria for conveying and goaf filling, resulting in a high strength of the filling body.
