Experimental study on behavior of mortar-aggregate interface after elevated temperatures

Wan WANG, Jianzhuang XIAO, Shiying XU, Chunhui WANG

Frontiers of Structural and Civil Engineering 2017, Volume 11, Issue 2,   Pages 158-168 doi: 10.1007/s11709-016-0374-6

Abstract: A push-out test program was designed and conducted to study the meso-scale behavior of mortar-aggregatetemperatures ranging from 20°C to 600°C with the concept of modeled concrete (MC) and modeled recycled aggregateThe properties of recycled aggregate concrete (RAC) may be more sensitive to elevated temperatures thanthose of natural aggregate concrete (NAC) due to the fact that the interfacial properties of RAC are

Destructive and non-destructive evaluation of concrete for optimum sand to aggregate volume ratio

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 6,   Pages 1400-1414 doi: 10.1007/s11709-021-0779-8

Abstract: As such, a detailed experimental investigation was carried out to evaluate the effect of sand-to-aggregate, cement content (340 and 450 kg/m3), water-to-cement ratio (0.45 and 0.50), and maximum aggregateThe careful analysis demonstrates that aggregate proportions and size need to be optimized for formulatingmix designs; optimum ratios of s/a were found to be 0.40 and 0.44 for the maximum aggregate
