    Abstract

    © 2016, Central South University Press. All right reserved. The compression test, splitting test and wall diagonal compression test of the samples made out of recycled concrete aggregates were conducted under static load to study their failure characteristics and strength behavior of cement-stabilized rammed earth materials. In particular, the in-plane shear behavior of rammed earth wall was investigated, and the effect of different reinforcement on the in-plane shear behavior of panels was also studied. Finally, according to the shear strength formula proposed in the concrete code AS 3600-2009, the correlation between shear strength and compressive strength was discussed for the cement-stabilized rammed earth. The results show that this material has a compressive strength of 8.68-10.11 MPa, the shear strength of 1.55 MPa and the tensile strength of 1.01-1.23 MPa. All the reinforcements embedded in the panels increase the shear strength and pseudo-ductility of panels, respectively ranging from 6% to 42% and from 35% to 92%, but only the panel with polypropylene fibers exhibits a toughness increment up to 49%. And the results of the panel with steel mesh show that the reinforcement position and orientation have a great influence on the bonding between the steel bars and the rammed earth matrix. The calculated shear strength according to the formula in the code AS 3600-2009 is greater than that of the panel vertically rammed in layers.
