Strength deterioration and service life research on subsea tunnel grouting materials

Grouting specimens made with ordinary Portland cement at different water-cement ratio(0.8,1.0 and 1.2) or ordinary Portland cement at water-cement ratio of 1.0 incorporating 10% fly ash(FA) or 20% FA,ground blast furnace slag(GBFS) with the replacement of 15% or 30%,or 10% microsilica(MS) and 20% MS were made and exposed to seawater environment.Compressive strength of specimens was measured.Effects of seawater concentration,water-cement ratio and mineral admixtures on the compressive strength of...
