Embodiment 1
[0017] Example 1: steam-cured glass fiber reinforced plastic GFRP bar concrete walking slab I includes: glass fiber reinforced plastic GFRP bar, C45 concrete and resin color micro-surface 1. The diameter of glass fiber reinforced plastic GFRP bar is Φ10mm, and its composition is 72 volumes of glass fiber and 28 volumes of epoxy resin. The mix ratio of C45 concrete: 420 parts by mass cement: 175 parts by mass water: 720 parts by mass sand: 992 parts by mass Gravel: 88 parts by mass Fly ash: 5 parts by mass of admixture, water-cement ratio W / C=0.417. Such as figure 2 , image 3 As shown, the glass fiber reinforced plastic GFRP bars are poured into the concrete, and the design parameters of the glass fiber reinforced plastic GFRP bar concrete walking slab I are shown in Table 4; followed by steam curing, as shown in Figure 4 As shown, that is, at room temperature, the static stop section A at room temperature is 2h, the heating section B is 2h, the constant temperature sectio...
