由于土壤固化剂可以结合当地土作为主要路基建设材料,因而在技术上和经济上都具有重要意义,我国公路建设改良土壤的产品仍大多沿用石灰、水泥、工业矿渣,砂、或这些材料的混合物,随着环境保护对道路工程用石料、河砂、山砂等自然资源开采的严格限制,土壤固化剂作为一种广泛易得而又环保经济实用的新型替代材料具有现实的意义。 Since soil curing agent can be combined with local soil as the main subgrade construction material, it is technically and economically important. The products of road improvement soil in our country are still mostly used in lime, cement, industrial slag, sand, or a mixture of these materials As environmental protection severely limits the exploitation of natural resources such as rock, river sand and mountain sand in road engineering, soil hardener is of practical significance as a new alternative material widely available and environmentally friendly.
