The problems of easy cracking, high brittleness, and low bond strength ordinary Portland cement sulphoaluminate (OPC-SAC) composites limit their application as rapid repair materials. In this study, glass fibers (GFs) were added to OPC-SAC with the content 0.0–1.5% improve properties. Fluidity, mechanical properties, drying shrinkage properties researched, microstructure was characterized by SEM ICT. Hydration products at different curing ages studied XRD FTIR. results showed that GFs improved composites. 28 d flexural strength, compressive specimens 0.5% reached maximum values, increasing 22.1%, 12.1%, 82.9%, respectively, compared control group without GFs.. significantly inhibited composites, inhibitory effect magnified GFs. Adding could reduce porosity specimens, decrease volume proportion pores (>10 mm3), refine pore structure. summary, is recommended optimal be into

In this work, the shield inert synchronous grouting material were fabricated using slag powder, fly ash and silica fume as raw materials. view of inevitable influence environmental factors on materials after construction, resistance single liquid active was comparatively investigated by water absorption test, impermeability chemical corrosion test well frost test. Water confirmed that possessed hygroscopic rate 10.12%, which is lower than 11.31% counterpart 48 h immersion. The pressure high 0.93 MPa, also higher Chemical showed exhibibted better salt erosion resistance, acid alkali compared with under same conditions. Frost strength exhibited loss mass 1.64% 0.33%, 1.92% 0.62% 10 freeze-thaw cycles. phase changes at different ages X-ray diffraction (XRD), microstructure evolution scanning electron microscopy (SEM). It observed key for enhanced formation a large number cementitious crystalline substances in hydration process, effectively improved compactness internal On basis, work mechanism powder-fly ash-silica fume-based proposed.
