结果表明：高等公路水泥路面加铺沥青层技术是处理旧水泥路面行之有效的方法之一，在高等级公路水泥路面改建中发挥着重要作用。

The large and medium-sized cement enterprises in our country generally use high-quality bituminous coal and low quality coal can not been used.

随着优质资源的日益稀少，水泥工业逐渐向利用低质燃料的方向发展，但局限于当前的水泥生产工艺水平，能够适应水泥生产的煤种范围比较窄，一般我国水泥工业中的大中型企业多使用优质烟煤，劣质煤很难得到应用。

By means of silty fine sand layers, the paper researches the grouting systems that consists of cement single liquid grouting material, MC super and thin cement single liquid grouting materials, cement and water glass of liquid grouting materials, MC super and thin cement and water glass of liquid grouting materials, TGRM single liquid grouting material, and HSC single liquid grouting material, respectively. The grouting design, grouting parameter, grouting result check of the karst cave No.2 and two passive countermarch returns to fill the situation are analyzed, which can provide an important reference for future tunnels under similar geological conditions.

Differential coefficient and difference simulation equation of gray model GM (1, 2), representing the relationship between 28d compressive strength and 4-32μ m particle content respectively is

颗粒粒级范围对强度的灰色系统关联度分析结果表明：对于普通硅酸盐水泥，4-8μm颗粒含量对水泥3d抗压强度的影响最大，8-16μm颗粒含量对水泥28d抗压强度的影响最大，对水泥90d抗压强度，则16-24μm颗粒的影响最大。28d抗压强度与4-32μm颗粒含量灰色模型GM（1，2）的微分方程和差分模拟式分别为

To explore the hydration process of Portland cement-fly ash system, the reaction degree of fly ash and Portland cement,non-evaporable water content,amount of hydration products,porosity and compressive strength of pure cement pastes and cement-fly ash pastes were studied at various curing ages,water-to-binder ratio,and fly ash replacement percentages.

为考察粉煤灰对水泥水化进程的影响，系统研究了水泥粉煤灰浆体在不同养护龄期、水胶比、粉煤灰掺量下水泥和粉煤灰反应程度、非蒸发水数量、水化产物数量、孔结构和浆体力学性能。

The grindability of cement clinker was better than ordinary Portland cement, for example, on the same condition it took the high alite content Portland cement clinker 4.5min to grind to a specific surface area of 320m2/kg, while the o...

同时这种水泥熟料的易磨性优于普通硅酸盐水泥熟料：在相同条件下，磨细到比表面积320m2/kg时，这种熟料需要4.5min，而普通硅酸盐水泥熟料则需要8.0min。同时对该熟料进行了岩相检验分析。
