在全珊瑚骨料海水海砂硫铝酸盐水泥混凝土（FCASS-CSAC）中用纤维增强复合材料（FRP）筋替换传统钢筋可有效解决钢筋锈蚀问题，但FRP筋与FCASS-CSAC的粘结机理尚不明晰。为了探明二者粘结性能退化规律，本工作对18个中心拉拔试件进行了测试，分析了FRP筋种类（BFRP和GFRP）和粘结长度（5d、7.5d、10d）对其粘结性能的影响。结果表明：对于直径d为10 mm的FRP筋材，在不考虑肋形的情况下，玄武岩FRP（BFRP）筋增强的粘结性能普遍优于玻璃FRP（GFRP）筋，其粘结强度总体比GFRP筋高约40%；当BFRP和GFRP筋的粘结长度为5d时粘结应力较高，其中BFRP粘结体系中5d粘结长度的强度比7.5d和10d的分别高出约30%和60%。结合试验结果，提出了考虑粘结长度影响的FRP筋与FCASS-CSAC的粘结强度预测公式，开展了其粘结性能的有限元仿真分析，并对不同加载速度和混凝土强度进行模拟预测，粘结-滑移曲线的预测分析结果均与试验结果吻合较好。

Introduction

In marine environments, the conventional steel reinforcement is prone to corrosion, leading to severe damage to concrete. Additionally, the deficiencies of ordinary concrete in terms of resistance to marine corrosion and impermeability significantly shorten the service life of marine concrete structures, which has attracted widespread attention. To enhance the durability of marine concrete, researchers are actively exploring new solutions. Among these, the use of FRP (Fiber Reinforced Polymer) reinforcement to replace traditional steel bars effectively addresses the issue of steel corrosion. Calcium sulfoaluminate (CSA) cement concrete, with its characteristics of early strength, high strength, corrosion resistance, and excellent impermeability, is particularly suitable for marine concrete structures that require high early-strength and durability. Based on this, the present study investigates the specific impact of different bond lengths of GFRP (Glass Fiber Reinforced Polymer) and BFRP (Basalt Fiber Reinforced Polymer) reinforcement on the bonding performance of the FRP-CSA full-coral aggregate concrete system.

Methods

This study investigated the influence of different bond lengths of FRP bars in full coral aggregate seawater sea-sand sulphoaluminate cement concrete (FCASS-CSAC) on the bond properties. This study used two different types of bars (GFRP and BFRP) and three different bond lengths (5 d, 7.5 d, 10 d, where d represents the diameter of the bars) to cross combine into 6 different types of specimens. All specimens were demolded after 24 h treatment and cured for 28 d in a standard curing chamber (temperature of (20±2) ℃, relative humidity of 95%). Subsequently, compressive strength tests and central pull-out tests were conducted to investigate the bond performance between FCASS-CSAC and FRP bars.

Results and discussion

When the bond length of BFRP and GFRP reinforcement bars is 5 d, the bond stress is generally higher than when the bond length is 7.5 d or 10 d. Specifically, for BFRP bars, the bond strength at a bond length of 5 d is approximately 30% and 60% higher than that at bond lengths of 7.5 d and 10 d, respectively. The bonding performance of BFRP and GFRP reinforcement bars was compared, and the results show that, in the absence of ribbed features, BFRP reinforcement typically exhibits superior bonding performance, with the bond strength generally about 40% higher than that of GFRP bars. This suggests that BFRP reinforcement has a potential advantage in providing stronger bond strength, which may be related to its material properties and the way it interacts with the matrix.

Conclusions

The main conclusions of this study are summarized as follows. The bonding performance of BFRP reinforcement with FCASS-CSAC is generally superior to that of GFRP reinforcement, with an overall bond strength about 40% higher. The bond strength of both types of reinforcement decreases as the bond length increases, with BFRP reinforcement showing a significantly higher bond strength at a bond length of 5 d compared to 7.5 d and 10 d. Based on the experimental results, an empirical formula for predicting bond strength was proposed. Furthermore, finite element simulation analysis was conducted, and the analysis results showed good agreement with the experimental findings.
