“…Cement-based materials have been widely used in building construction and transport engineering due to their superior strength, anti-corrosion resistance, and low cost [1][2][3]. Nowadays, the characteristics of ultra-high rise, high-speed, and large-flow traffic in building construction and transport engineering became more prominent [4,5].…”

This study proposes a new cement mortar incorporating damping aggregate (DA) and investigates the mechanical properties and damping property of the cement mortar. Four types of DA were prepared, lightweight aggregate presaturated water and three types of polymer emulsion. Further, the effects of polypropylene fiber and rubber powder on the performance of the cement mortar were studied. The experimental results showed that the damping ratio of specimens containing 70% DA was approximately three times higher than that of the reference mortar, with a slight decrease in the mechanical properties. Adding fiber was more effective than rubber powder in improving the damping ratio of the cement mortar, and the optimal dosage of fiber was 0.5%.

“…The durability is defined as the ability to resist a specific loading or environmental condition for a specific time under a suitable load and environmental condition [89]. Li et al [88] studied the durability of SWSSC-filled GFRP/CFRP/BFRP tubes during six months by exposing the specimens to artificial seawater containing 3.5% salt solution at the temperature of 40 ˚C.…”

“…The fiber reinforced polymer (FRP) was widely investigated in the RC members for the past few years [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ]. Several researchers have been working toward increasing the concrete strength by attaching carbon fiber sheets (CFS) with high stiffness to the concrete surface [ 16 , 17 , 18 ].…”

Effect of Strengthening Methods on Two-Way Slab under Low-Velocity Impact Loading

et al. 2020

In this study, the performance of reinforced concrete slabs strengthened using four methods was investigated under impact loads transferred from the top side to bottom side. The top and bottom sides of test slabs were strengthened by no-slump high-strength, high-ductility concrete (NSHSDC), fiber-reinforced-polymer (FRP) sheet, and sprayed FRP, respectively. The test results indicated that the test specimens strengthened with FRP series showed a 4% increase in reaction force and a decrease in deflection by more than 20% compared to the non-strengthened specimens. However, the specimen enhanced by the NSHSDC jacket at both the top and bottom sides exhibited the highest reaction force and energy dissipation as well as the above measurements because it contains two types of fibers in the NSHSDC. In addition, the weight loss rate was improved by approximately 0.12% for the NSHSDC specimen, which was the lowest among the specimens when measuring the weight before and after the impact load. Therefore, a linear relationship between the top and bottom strengthening of the NSHSDC and the impact resistance was confirmed, concluding that the NSHSDC is effective for impact resistance when the top and bottom sides are strengthened. The results of the analysis of the existing research show that the NSHSDC is considered to have high impact resistance, even though it has lower resistance than the steel fiber reinforced concrete and ultra-high-performance-concrete, it can be expected to further studies on strengthening of NSHSDC.
