摘要：
A cementitious product and method of modifying the properties of a low or medium density FRC product by providing a predetermined pore size distribution. The pore size distribution is obtained such that in critical zones of the distribution, the pore volume is substantially equivalent to or less than the pore volume in a respective critical zone of a conventional high density FRC product. The resultant material provides improved properties over conventional medium density FRC products, in particular improved freeze/thaw durability and/or improved workability.
摘要（中）：
一种胶结产物和通过提供预定的孔径分布来改变低或中密度FRC产物的性质的方法。 获得孔径分布，使得在分布的临界区域中，孔体积基本上等于或小于常规高密度FRC产物的相应临界区中的孔体积。 所得材料提供比常规中密度FRC产品改进的性能，特别是改进的冷冻/解冻耐久性和/或改进的可加工性。
