Gypsum crystals bridging probability

Probabilities of Bridging, for Gypsum Crystals and Amorphous Silica Particles as a Function of the Contact Time, t, and the Degree of Supersaturation, a... 

In the process of the formation of crystallization strnctures, the isolated small crystallites, which are the primary elements of the emerging strnctnre, appear to be randomly oriented toward each other. It was therefore of interest to investigate the effect of the crystallographic orientation of the gypsum crystals in contact on the probability of bridging. 

Results summarized in Table 6.7 indicate that the formation of crystallization contacts was facilitated by the applied compressive force,/ In the case of the same applied force, the probability of contact formation depended on the crystallographic orientation of the gypsum crystals. The effect of compressive force on the probability of bridging must be primarily related to the properties of the gypsum crystals. Among all materials used in the study, gypsum was the softest with stress-dependent solubility its concentration therefore increased in the contact zone.
