Influence of aggregate mineralogical composition on water …

The differences in moisture durability could be attributed to the mineral composition and water absorption of aggregates. As previously discussed, there is a strong correlation (R 2 =0.999) between certain aggregate minerals and aggregate moisture absorption. On this basis alone, it should be expected that degradation of bond strength …
