Study on Key Mechanical Parameters of High-Strength Grouting Material

In order to better design and calculate in infrastructures, it is necessary clarify the key mechanical parameters of structural materials, such as axial compressive strength, elastic modulus Poisson’s ratio. High-strength grouting material (HSGM) have begun be used materials with development large complex structures. A number test dates were analyze relationship between strength cubic HSGM paper. ABAQUS software was model specimens strain cloud maps concrete compared analyzed. By considering two-phase (sand paste) composites, component derived, results properties different ratios sand cement for verification. The show that closer than material, which accords finite element analysis results. high-strength conforms theoretical derivation material. composition one main factors affecting modulus. ratio range 0.25 ± 0.01 by statistical analysis.
