Abstract

Steel slag as the research object, steel slag cementitious activity was excited by sodium silicate, sodium sulfate, sodium carbonate, sulfuric acid and acetic acid, respectively. According to relevant standard, the activity index was measured after test for 7 and 28 d. The results showed that sodium silicate, sodium carbonate and acetic acid can better excitation steel slag cementitious activity, the steel slag cementitious activity was best with sodium silicate 1.6%(?), sodium carbonate 2.4%(?) and acetic acid 0.10 mol/L. Sodium sulfate and sulfuric acid can excited steel slag cementitious activity good, especially in the early stage, the steel slag cementitious activity was best with sodium sulfate 3.2%(?) and sulfuric acid 0.10 mol/L.

Key words： steel slag; activator; steel slag cementitious activity; chemical excitation; cementitious materials
