Results show that, following the leaching time extending, the leaching concentrations of heavy metals and lixiviate toxicity of heavy metals increase in the fly ash. When the ratio of liquid and solid add, the leaching concentrations of heavy metals obviously become big, and the Cd's leaching concentration is the biggest, when the ratio of liquid and solid is 90, the Cd's leaching ratio exceed the percent of 70. At the time pH is about 7, the leaching concentrations of heavy metals are the lowest. When the grain size is the bigger or little, the leaching concentrations of heavy metals are lower, however when the grain size is 250-900 μm, the concentrations are higher. After fly ash melt in the high temperature, the lixiviate toxicity of heavy metals greatly reduce, which explains that the effect of melting on heavy metals' stabilization is very good.

结果表明，随着浸出时间的增加，飞灰绝大部分重金属的浸出浓度增高，浸出毒性增强；液固比增加，大部分重金属的浸出率大大提高，其中重金属Cd的浸出率最大，在液固比为90时，飞灰中的Cd的浸出率达到70%以上；pH为中性左右的时候，医疗垃圾飞灰中的大部分重金属的浸出液浓度最低；颗粒尺寸在较大或者较小时，医疗垃圾飞灰中的大部分重金属浸出浓度较小，大部分重金属在颗粒尺寸250～900 μm时，重金属的浸出浓度较高；飞灰高温熔融后，重金属的浸出毒性大大降低，说明熔融对重金属有很好的固化效果。

The hydrated products and pore size distribution of high road fly ash cements were studied by means of XRD,DTA,Mercury porosimeter,etc.,The experiment results showed that C-S-H gel,AFt were the main hydrated products in high road fly ash cement,but the contents of Ca 2 were lower.

实验结果表明，公路粉煤灰水泥的主要水化产物是C -S -H凝胶、AFt及少量的Ca 2 。

Test results show that the shear strength parameters of the fly ash with high calcium oxide content can make a notable change due to pozzolanic action and frost and thaw cycles, but for the fly ash with low calcium oxide content this phenomenon is not very obvious,and the influence of the frost and thaw cycles can be neglected.

试验结果表明，高氧化钙含量的粉煤灰的强度指标受上述两种作用的影响显著；低氧化钙含量的粉煤灰的强度指标在凝硬作用下也有所提高，但基本不受冻融作用的影响；干贮粉煤灰的渗透系数受凝硬和冻融作用的影响较小。

The direct relationship between the strength coefficient of fly ash and main factors,such as the pozzolanic activity index,content of fly ash,water binder ratio and curing age,is given.

提出了粉煤灰强度效应因子k的动态预测模型，该模型建立了粉煤灰强度效应因子与粉煤灰火山灰活性指数、粉煤灰掺量、水胶比、龄期等主要参数之间的直接联系，并考虑了粉煤灰品种、水泥品种等其它因素的影响。
