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。

Gravi ty and reentrainment were identified to be the main concerns. A simple reformati on of the ash hopper could be made to increase the ash separation efficiency wit h the addition of special devices.

研究结果发现，重力分离和二次夹带是灰斗气固现象中的主要矛盾，灰斗简单改型可以提高灰斗分离的效率，但工程应用仍需加装专门的分离装置。

Generally, the amount of coal fly ash is four times of coal bottom ash, therefore, it needs more techniques to reutilize.

煤灰可分为底灰及飞灰二大类，其中飞灰产量约为底灰的四倍，因此需更积极寻求飞灰多方面之用途，以提升飞灰之利用量。

The source profile and relative contribution to receptor of determined soil/fly ash,constrction locate,incinerator,sea spary,exaust and non-ferror was deduced by PMF2. Among them,soil and fly ash contributes 40% to receptor.Enrichment factor analysis were also performed to identify possible sources in Beijing urban area with die data measured in the study.
