drying shrinkage การใช้

Differential stresses that develop as a result of non-uniform drying shrinkage are directly related to the rate at which the solvent can be removed, and thus highly dependent upon the distribution of porosity.
This allows a higher solids content to be used, or allows a fluid slip to be produced with the a minimum of water so that drying shrinkage is minimised, which is important during slipcasting.
"' Expansive cements "'contain, in addition to Portland clinker, expansive clinkers ( usually sulfoaluminate clinkers ), and are designed to offset the effects of drying shrinkage that is normally encountered with hydraulic cements.
