提高石灰土强度的技术措施

Technical measures of improving the strength of rendzinas

通过对石灰土强度形成机理的深入研究 ,石灰土强度最终形成主要是由于离子交换、结晶作用 ,而与碳酸化作用基本无关。介绍了合理地利用CO2 ,加入适量的外掺剂和加入适量的外加物 ,可以作为提高石灰土强度抗压、抗拉、抗剪和抗冻强度的有力措施。

Through research on rendzinas strength's forming me chanics, the writer points out that rendzinas strength's final forming mainly dues to ionic exchang e and crystal, not to carbonation, making use of CO 2 rationally, addin g proper extra adulterating agent and substance, may be the effective measures o f improving strength of rendzinas such as r esisting compression, tension, shear and freezing strength. New thought is put f orward to improve strength of rendzinas in the future.
