Fundamental Issues Towards Unified Design Theory of Recycled and Natural Aggregate Concrete Components Article

Jianzhuang Xiao, Kaijian Zhang, Tao Ding, Qingtian Zhang, Xuwen Xiao

Engineering 2023, Volume 29, Issue 10,   Pages 188-197 doi: 10.1016/j.eng.2023.03.017

Abstract:

In the past 20 years, recycled aggregate concrete (RAC), as a type of low-carbon concrete, has becomeConsequently, demands for a unified design of natural aggregate concrete (NAC) and RAC components havedemonstration of the strength determination, compressive constitutive relationship, and design method of concreteThe coefficient of variation of RAC strength is found to be generally higher than that of NAC strengthIt is believed that this study enriches and develops the basic theory of concrete structures.

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-aggregateconcrete (MC) and modeled recycled aggregate concrete (MRAC).The 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 arelower than those of NAC, and are deteriorated at lower temperatures.
