PERFORMANCE TEST AND RESULT ANALYSIS OF HIGH PERFORMANCE CONCRETE

Аннотация

The sulfate corrosion resistance of shotcrete is: benchmark ≈ mineral powder alone < fly ash alone < compound mix ratio, and the compound mix ratio of mineral admixture (cured under the same conditions) is resistant to sulfate corrosion The ability is worse than that of compound mineral admixture (standard health). Generally speaking, the ability of shotcrete to resist sulfate corrosion is poor. The reason is that the quality of shotcrete is not high and the density is not very good.
