摘要
碱渣是氨碱法生产纯碱时产生的工业废料,将碱渣与粉煤灰拌和制成工程土,并对其进行室内物理力学指标试验研究.结果表明,新型工程土无侧限抗压强度介于0.22～0.28 MPa之间,一定程度上能将其应用于工程实际,能够合理地解决碱渣废料的堆积及污染问题.
Soda residue is a kind of industrial waste which is used as main material of ammo- mia soda and soda ash in the production. Soda residue and fly ash are mixed into engineering soil, and the physical and mechanical indexes of engineering soil are studied through indoor test. The results show that unconfined compressive strength of new engineering soil ranged between 0. 22-0.28 MPa, to some extent, it can be used for engineering and the accumulation and pollution problems of soda residue can be solved.
