The chemical requirements for limestone filler are equivalent to
limestone filler. The induction period is shortened and an extra heat production peak sometimes occurs, even at the lowest testing temperatures. The higher the amount of filler and the higher the testing temperature, the more pronounced the peak is. Bentz [30] studied the effect of adding limestone fines by computer simulation.
At the same age, the ettringite crystals present in reference paste (Fig. 9 a) are very small compared to ettringite crystals of pastes with 25% RRHA2 and 5% limestone filler (9c); pastes with 25% RRHA1 and 5% limestone filler (Fig. 9 b) show large monosulphoaluminate and ettringite at final transformation phases while pastes …
