Table 1 Quadratic mean roughness (in nm) of cement powders with different concentrations of chitin and aging times on a sulfate environment.
Figure 5 shows the elasticity and adhesion for the sulfate systems. The measurement error is assessed from the standard deviation during the acquisition of at least 360 data points
