2021-5-6  It is common to use cement additives that increase the mechanical strength by chemical activation, without changing the cement surface and particle size distribution. Alkanolamines are frequently used and are able to increase the compressive strength (at different or all age) by max. five MPa. Typical examples are SikaGrind®-200 and SikaGrind

Effect of additives on the compressive strength and

No differences were detected between the compressive strength values of 21 hours and 60 days. While 10% CaCl 2, 20% and 30% PMMA produced values significantly lower than the PC-control, 30% spherical alloy significantly improved the compressive strength of the reinforced PC (p < .05). In summary, all additives significantly reduced the setting
