| titleOfInvention | Precast concrete slab track panel composition using low viscosity-high flow cement |
| abstract | The present invention relates to a concrete composition for precast slab track panels that achieves high fluidity for improving productivity and quality of precast secondary products using low viscosity high flow cement and reaches demolding strength of 35 MPa at 16 hours. . The present invention is "concrete composition in which a binder, coarse aggregate, fine aggregate and water are combined, and the binder has a specific surface area of 4,500 to 5,200 cm 2 / g, total alkali content (TA) of 0.6% or less, and a residual ratio of 45 μm or less, 2.0 wt% Hereinafter, as a low viscosity high flow cement having a SO 3 content of 3.5 to 3.7 wt%, 430 to 440 kg per 1 m 3 , water-binding ratio of 33 to 34 wt%, fine aggregate ratio of 40 to 48 vol%, and a polycarboxylic acid-based water reducing agent 0.8 ~ 1.3wt% of the binder is added, maintaining the slump flow 450 ~ 500mm for 1 hour after blending, under constant curing process of atmospheric steam curing for 5 hours, 16 hours of compressive strength over 40MPa and age 28 days compression It provides a concrete composition for precast slab track panels, characterized in that physical properties of strength of 55 MPa or more are expressed. |
