Influence of specimen size and curing temperature on volume expansion of steel slag sand mortar ;2. This research deals with the mechanical mechanism of expansion of steel slag sand mortar through the measurement of strength and expansion rate.

通过力学性能和80℃水热加速养护条件下砂浆棒自由线性膨胀率实验，结合SEM等微观测试技术，分析探讨了不同基体强度对钢渣砂砂浆膨胀行为的影响及水热养护不同龄期的力学性能与自由线性膨胀率的关系，从力学角度阐述了SSM膨胀破坏的机理。

This research deals with the mechanical mechanism of expansion of steel slag sand mortar through the measurement of strength and expansion rate. The results indicate that the improvement of matrix strength could lower the expansion rate of steel slag sand mortar, extend the cracking age, reduce the degree of cracking but couldn't prevent the specimens made with steel slag from crack.

It is suggested that policy should be on the basis of minimum irrigation, soil mulching and straw and manure utilization, and the leading one of its measures should be to use high-salined groundwater as an accompaniment of river water, by the integration of the power-pumped-Yellow-River irrigation system and well-water irrigation system, to lower the watertable and reduce the irrigation cost. Thus the dynamic balance of salts, as well as the prevention and reclamation of salinization, will have been kept through the management of water and soil organic matter.

在此基础上结合国内外盐渍化防治及盐渍土改良利用方面的发展趋势，笔者提出应该以水盐平衡理论为指导，以节水灌溉为前提，以地面覆盖和土壤培肥为基础，以井排系统与引黄灌水系统并网，井渠混灌，降低地下水位为突破口，通过对水分和肥力的调控和管理达到对盐分的调控和管理，使盐分在土体或灌区实现动态平衡，从而达到土壤盐渍化的预防和治理。
