Selfhealing bone cement EurekAlert

Selfhealing bone cement EurekAlert

Jan 01, 1992 Supporting (load-bearing) cement increases the effective intergrain contact area, thereby increasing a sandstones resistance to compaction. Supporting cement usually preserves more pore space than it occupies. This is in direr contrast to passive (non load-bearing) cement, which may destroy even more effective pore space than its solids occupy.
