Effect of polycarboxylate and crushed quartz in UHPC ...
2013-7-1 · With crushed quartz, an additional grain size is found, intermediate between the grain sizes of cement and silica fume. The result is to increase the density of the initial packing and thereby the final density of UHPC. This phenomenon is more efficient when the crushed quartz is homogeneously distributed in the paste.
