水泥改良泥质红砂岩抗压强度试验研究

摘要

研究表明,经改良后的红砂岩用作路基筑料可大大改善其物理和工程性质,提高道路路基的使用耐久性.本文借助已在露天崩解的泥质红砂岩,并通过室内击实实验和无侧限抗压强度实验,重点研究不同水泥掺入量对无侧限抗压强度的影响,提出改良露天崩解泥质红砂岩的较佳水泥掺量.%Studies show that improved sandstone used as subgrade material can largely improve it' s physical and engineering properties, also strengthen the durability of the subgrade. Based on the uncon-fined compressive strength of disintergraded muddy sandstone, this thesis mainly studies the influence of different cement adding quantity to it, and put forwards better cement adding quantity on improving the open-air disintergraded muddy sandstone.
