“…Water-releasing role of lightweight aggregate provides a remarkable internal curing effect on cement-based materials during the hydration process of cement, which conducive to improve the microstructure and performance of cement-based materials [6]. Nowadays, the cement-based materials containing lightweight aggregate have been extensively studied for the physical and mechanical performance, as well as its durability [24,25]. However, studies on the effects of lightweight aggregate presaturated water and polymer emulsion on the damping property of cement mortar is still very limited, especially comparative performance of the cement mortar modified with polypropylene fiber and rubber powder.…”

“…Preplaced aggregate concrete (PAC), a novel low-cement-consumption concrete, is prepared by placing coarse aggregate into formworks and then injecting the grout mortar into the void between the coarse aggregate [1,2]. Based on the special preparation technology, compared with normal concrete (NC), development of PAC could achieve a number of benefits, typically in saving cement, solving the segregation of coarse aggregate, reducing energy consumption during the concrete mixing process, increasing concrete stiffness, reducing concrete shrinkage and so on [3][4][5][6][7][8][9]. In recent years, PAC has been used in concrete repair engineering, underwater construction, massive concrete structures, concrete track construction, nuclear power plant structures and so on [10][11][12].…”

“…Aggregate accounts for approximately 60-70% of all raw materials in the concrete production [3][4][5][6]. However, concrete consumption is expected to increase with the continuous growth of the infrastructure industry [7,8]. Consequently, non-renewable aggregate resources may get exhausted [4].…”
