ABSTRACT Mechanical properties of soil stabilized cement made from kiln ash, which consists of clinkers made from kiln ash only or the kiln ash with CaSO4-CaF2 compound mineralizer and certain amount of gypsum are studied. Moreover, the effects of burning temperature and gypsum content on the strength of the stabilized soil with kiln ash cement have been researched.

摘 要 研究了用纯窑灰、掺CaSO4-CaF2复合矿化剂的窑灰烧熟料与适量石膏混合配制的窑灰水泥稳定土的力学性能，并探讨了烧温度和石膏掺量对窑灰水泥稳定土强度的影响。

Gypsum mine owned companies rich reserves of high quality, an area of 3 square company, has proven reserves of 390 million tons, the annual extraction capacity of 300,000 tons, gypsum dihydrate of the total reserves of 40 percent, of which an egg cream Dihydrate 10-15% of gypsum, in more than 95 percent grade, crystal water in more than 18 per cent, accounting for two gypsum plaster dihydrate of 30-40 per cent, with an average grade of 85 percent or more, crystal water in more than 17 per cent, 3 Sulphur dioxide in more than 40 percent, 3 gypsum, with an average grade of 70 percent or more, the crystallization of water in 13 percent or more, three more than 35 per cent in sulphur dioxide, widely used in cement industry.

公司所属石膏矿山储量丰富、品质优良，占地3平方公司里，已探明的储量为3.9亿吨，年开采能力为30万吨，二水石膏占总储量的40%，其中一级蛋膏占二水石膏10-15%，品位在95%以上，结晶水在18%以上，二级膏占二水石膏的30-40%，平均品位在85%以上，结晶水在17%以上，三氧化硫在40%以上，三级石膏，平均品位在70%以上，结晶水在13%以上，三氧化硫在35%以上，广泛用于水泥行业。

The natural result of gypsum plaster and water containing dihydrate anhydrite, and contained chemical components, in particular the complex trace elements, it will cement additives do not have a different series of deep radical solution or condensate, and other phenomena.

而天然石膏因含有二水石膏和无水硬石膏，加上所含化学成分，特别是微量元素复杂，反而会对水泥外加剂不同系列产生不相深溶或急凝等现象。

The net cement with bentonite can form hydrogen key which can improve the felt of the systematic and are wail for eventual strength; The main mechanism of J-85 accelerator to accelerate concrete coagulating are in alkalescence condition to make aluminate and gypsum link and block the building of calcium and aluminium sulphate around cement granule; Polypropylene acid can improve early strength of cement through altering the thickness of hydroxide in cement grout.

添加膨润土后的水泥净浆中形成了氢键，提高了体系的粘结性，对后期强度发展有利； J-85速凝剂加速混凝土凝结的主要机理就是在碱性条件下，使铝酸盐和石膏结合，阻碍水泥颗粒周围的硫铝酸钙即钙钒石的生成，从而使水泥迅速凝结；聚丙烯酸通过改变水泥浆体中羟基的浓度从而提高水泥试块初期强度。

After analysing good applied foreground of FGD gypsum,the paper indicates the problems that will meet in using FGD gypsum,and puts forward synthetical measures in dealing with FGD gypsum.lt includes: stabilizing the outputs and quality of FGD gypsum in projecting and running FGD equipments;the problems and treatment measures that FGD gypsum is applied to cement retarder;establishing the standards of FGD gypsum that fits Chinese situation consulting criterions of FGD gypsum abroad as soon as possible;calculating the short amount of gypsum in some provines and regions in China and the feasibility of technology and economy about FGD gypsumus use;suggesting that our nation come on some policies that encourage coal-burning powerplants to install FGD equipments , put FGD gypsum to rational use, in order that it will further develop multiple use of FGD gypsum in China.

在分析了我国脱硫石膏的良好的应用前景的同时，本文也指出了脱硫石膏推广应用中可能会遇到的问题，提出了一些综合处理措施。这包括脱硫装置设计和运行烟气脱硫设备过程中稳定脱硫石膏的产量和质量、脱硫石膏用作水泥缓凝剂的问题及处理措施、参考国外脱硫石膏产品质量标准尽快制定适合我国国情的脱硫石膏产品质量标准、推算我国缺少石膏资源的省区石膏的短缺量以及利用脱硫石膏的技术经济可行性，建议国家出台有关鼓励燃煤电厂安装烟气脱硫装置和合理利用脱硫石膏的一些政策，以进一步推进我国脱硫石膏的综合利用。

In pelletization process, slaked lime, clinker and calcined gypsum can be used as additives of which the hydration products of clinker have a binding effect of gypsum grains and a seed crystal effect for cement hydration. Thus, this technology is one of the best pelletization technologies known so far.

以熟石灰、水泥熟料、熟石膏为成粒助剂的成粒工艺，将磷石膏中和预处理统一于成粒过程中，熟料水化产物既对石膏颗粒起固化作用，又对水泥水化产生晶种效应，是国内外最好的成粒工艺技术之一。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
