Core tip: The early shrinkage and drying shrinkage of concrete gradually decrease with the increase of fly ash content, and the inhibitory effect of fly ash on early shrinkage is better than that of drying shrinkage; With the increase of mineral powder content, the early shrinkage of concrete increases while the drying shrinkage decreases; The addition of silica fume increases the early shrinkage and drying shrinkage of concrete, and this effect becomes more pronounced with the increase of silica fume content.
