Cyclic shear test and finite element analysis of TRC-reinforced damaged confined masonry walls Constr. Build. Mater. (IF 7.4) Pub Date : 2024-03-11 Boxue Wang, Shiping Yin, Fenghao Qu, Fei Wang
Due to the low level of seismic fortification during construction, masonry walls are highly vulnerable to earthquakes, but some walls remain in service after repair. To investigate the strengthening effect of textile-reinforced concrete (TRC) on the seismic performance of seismically damaged confined masonry (CM) walls, tests were conducted on four masonry walls, and a finite element model was established

Effects of siliceous iron tailings powder on performances of interface transition zone in concrete Constr. Build. Mater. (IF 7.4) Pub Date : 2024-03-11 Yun-hong Cheng, Hui-yu Ma, Jing-yu Zhang
At the meso-level, the interface transition zone (ITZ) is an important part of concrete and is closely related to the macroscopic properties of concrete. In this paper, the influences of siliceous iron tailings powder on concrete ITZ have been researched, in order to better reveal the mechanism of the powder as an auxiliary cementitious material in concrete. Based on XRD, SEM, hardness test and numerical

Effect of sand fineness modulus on SCC and SCLC properties Constr. Build. Mater. (IF 7.4) Pub Date : 2024-03-11 Yousef Nikzad, Moosa Mazloom, Mohammad Hosein Parhizkari
Due to the advantageous characteristics of self-compacting concrete (SCC) and self-compacting lightweight concrete (SCLC), the advancement of the SCC is considered a remarkable engineering feat. Fine aggregate is one of the main parameters of SCC; however, its effect on SCC and SCLC properties is somewhat restricted due to the limited extent of in-depth research conducted in this field. To investigate

Study on the characterization method of dynamic modulus for asphalt mixture under multi-factor coupling conditions Constr. Build. Mater. (IF 7.4) Pub Date : 2024-03-11 Guozhi Zheng, Naitian Zhang, Peng Wang, Songtao Lv
In the actual service process of asphalt pavement, the dynamic response of the pavement structure layer is induced by vehicle loads. The dynamic modulus is a crucial parameter for analyzing the mechanical response of asphalt pavement. Due to significant influences from temperature and loading frequency on test measurements, along with its time-temperature equivalence, it becomes imperative to investigate

Study on freeze-thaw deterioration model of new-to-old concrete based on pore surface fractal characteristics Constr. Build. Mater. (IF 7.4) Pub Date : 2024-03-11 Jingchong Fan, Bo Zhang
New-to-old concrete (NTOC) structures are widely used in engineering practice, the adhesive interface as a weak part is easily damaged under freeze-thaw environment. At present, most of NTOC deterioration models are grounded in the empirical summary of experiment data. In this paper, the bonding and durability of NTOC adhesive interface under different freeze-thaw cycles were investigated by splitting
