- Abstract:
- Cementitious materials were prepared by using a large amount of blast furnace slag and a small amount of metakaolin as raw materials，as well as the mixture of NaOH and Na2 Si03 as alkali activator．Effectsof average particle size of raw material，content of activator，curing time and temperature on the properties ofcementitious materials were studied．When the content of the activator was 1 2％，the compressive strength was1 7．66 MPa for the sample prepared from raw material granularity of 1 0 Ixm and cured at room temperature．However，it reached 27．9 1 MPa when the amount of activator increased to 1 6％．The resuhs also showed thatthe compressive strength increased with the extending of the curing time．The curing temperature at 80 oC wasmore suitable for the improvement of the early strength than other temperatures but the temperature shouldnotbe too high．
