Mineral admixtures exhibit significant enhancement effects on the seawater corrosion resistance of sulfoaluminate cement (SAC). This study systematically investigates influence mechanisms fly ash (FA), silica fume (SF), and slag powder (SP) physicochemical properties SAC-based materials. Experimental results demonstrate that FA effectively enhances fluidity fresh SAC paste while mitigating drying shrinkage. Under standard curing conditions, compressive strength mortar decreases with...
The present work studies the influence of water‐cement ratio and types mixing water on hydration process microstructure calcium sulphoaluminate (CSA) cement. Experimental tests setting time, physical properties, compressive strength, chemical shrinkage, X‐ray diffraction (XRD), scanning electron microscopy (SEM) CSA cement paste were carried out. XRD analysis confirmed that main product is ettringite in both freshwater seawater mixed with different w/c ratios. SEM properties test show low...
High autogenous shrinkage property is one of the disadvantages ultra‐high‐performance concrete (UHPC), which may induce early age cracking and threaten safety structure. In present study, different dosages calcium sulfoaluminate (CSA) cement were added in UHPC as an effective expansive binder. Hydration mechanism, property, compressive strength carried out to investigate effect CSA addition on mechanical properties UHPC. Scanning electron microscopy was also employed characterize intrinsic...
This research investigates the effect of seawater different concentrations on hydration process and microstructure calcium sulphoaluminate (CSA) cement. It studies CSA cement pastes via experiments carried out to determine initial final setting times, mechanical strength chemical shrinkage with X-ray diffraction (XRD), scanning electron microscopy (SEM) simultaneous differential thermal-thermogravimetric (DTA-TG) analysis. The DTA-TG XRD results showed that main products were ettringite...
This research studied the influence of three types open (short-straight, long-straight, semicircular) and different shapes closed steel fibers (triangular, rectangular, circular) with fiber contents by volume (0, 0.5%, 1%, 1.5%, 2%) on working mechanical performance reactive powder concrete (RPC). The results indicated that (1) number enclosed area formed would remarkably impact RPC; (2) semicircular improves RPC’s strength most among shapes; (3) short-straight works more effectively than...
This study aimed to explore the impact of three corrosive ions—SO42−, Cl−, and Mg2+—on hydration property calcium sulphoaluminate (CSA) cement. Cement paste was prepared using types sea salt ion solutions with varying concentrations as mixing water. The experimental program encompassed assessments porosity, compressive/flexural strength, heat hydration, pH pore solution, XRD, SEM analysis. To modulate environment, Ordinary Portland cement (10%) incorporated elevate enhance stability...
Abstract Calcium sulfoaluminate (CSA) cement is potential low-carbon cement; therefore investigation on ion exchange property at the steel/concrete interface of great importance to understand corrosion resistance and long-term durability properties steel reinforced CSA concrete. Moreover, there still a lack standard procedure for quantitative imaging analysis in study cementitious materials so far. In this study, we developed an updated technique investigate atomic information concrete by...
The precast reinforced concrete building is made of components, which are connected at the joints via reliable connection approaches. Therefore, study on stability and reliability connections should be conducted to improve safety integrity structure. In this paper, experiments two modes, i.e. corrugated pipe confined with spiral stirrup steel sleeve connection, were carried out. experimental tests consisted six specimens, including one cast-in-situ specimen, three specimens using stirrup....
Abstract This study set out to investigate the influence of SO 4 2− , Cl − and Mg 2+ on hydration sulphoaluminate cement by preparing a (CSA) paste using sea salt ion solutions with various concentrations as mixing water. The testing program included porosity, compressive/flexural strength, heat hydration, pH pore solution, XRD, SEM analysis. Ordinary Portland (10%) was added increase CSA environment improve stability ettringite provide more C-S-H gel observe formation M-S-H other...
Glass fibre reinforced cement (GFRC) is a composite material with great ductility but it undergoes severe strength and degradation ageing. Calcium sulfoaluminate (CSA) low carbon cement, more importantly, exhibits potential to produce ductile durable GFRC. This study focuses on mechanical performance, e.g., compressive strength, stress‐strain curve, freeze‐thaw resistance of CSA/GFRC as well its microstructural characteristics under temperatures. XRD was applied investigate the hydration...
