Figure 1: Scaling of concrete (w/c = 0.60; c = 300 kg/m³) in the cube test as a function of the number of freeze-thaw cycles (dolomite D1, D3, D5; reference limestone LL; cements C1, C2, C3; broken lines 20 mass % dolomite, otherwise 30 mass % dolomite in cement)
Figure 2: Dispersing effect of a polycarboxylate ether-based superplasticizer and duration of plastification as a function of the limestone content (35 mass % or 55 mass %) in the cement and the temperature (5°C, 20°C, 30°C). The doses of active substance of the superplasticizer (SP) and the cements’ water demands are shown in the key.
Figure 3: Carbonation resistance of mortar prisms (40 mm x 40 mm x 160 mm) after 140 days at 20°C and 65% rel. humidity (7d pre-storage under water) as a function of the limestone content in the cement and the w/c ratio
