Rubberized concrete exhibits enhanced toughness and sustainability but suffers from reduced mechanical strength, limiting its applications. This study the compressive strength of rubberized using hybrid steel/glass fibers. The results showed a positive synergy between fibers, with improvements in elastic modulus, Poisson’s ratio, peak strain, by 16.1%, 19.4%, 32.0%, 63.4%, 101.7%, respectively, at fiber content 0.8% (steel 0.6% glass 0.2%). A well-fitting stress–strain model was adopted for future constitutive simulations. advances understanding fibers under axial compression promotes application structural engineering.

Glass-fiber-reinforced polymer (GFRP)–steel composite bar, a novel building material, is promising longitudinal reinforcement for marine engineering in harsh environments. Previous research has primarily focused on altering individual parameters to assess their influence the performance of bars, lacking systematic and in-depth exploration. In this paper, tensile properties bars have been investigated by adequate experimental testing considering type inner steel bar thickness GFRP layer. Results show that although undergo elasticity, hardening, failure stages under loading, due differences interfacial bonding forces, ultimate mode with HPB300 relative slippage, while those HRB400 it fracturing. While ensuring good initial elastic modulus durability, preferable external layer be as small possible. However, should not less than 2 mm prevent misalignment which can negatively impact tangent during hardening stage strength. Furthermore, stress–strain constitutive model was developed validated. This offers universal framework accurately representing mechanical material across wide range parameters.

Abstract In recent years, research into the properties of seawater and sea sand concrete (SWSSC) has emerged as a prominent area investigation, alkali silica reaction (ASR) SWSSC is an urgent issue to be solved. However, little attention been paid effect K/Na on ASR SWSSC. order fill this gap, effects different products, pore structure, pH ion content, expansion were measured. The findings demonstrated that composition amorphous product ASR-P1 (K0.52Ca1.16Si4O8(OH)2.84-1.5H2O) exhibited inverse relationship with K/Na, whereas crystalline K-shlykovite (NaCaSi4O8(OH)3-2.3H2O) displayed direct correlation K/Na. increase K+ concentration leads decrease dissolution, which main reason for lowest degree in high group. transformation also resulted products groups. study provide foundation theoretical application field ocean engineering.
