This research shall be obtain that ocean-sand motor shall have more compressive strength early, but later strength shall descend, by means of non-standard sand mixing sample is quite obvious. By means of 50% ocean-sand substitutes for river-sand to mix fine aggregate compressive strength early shall be risen 20%~30%; Adds slag to ocean-sand or a half of river-sand and ocean-sand to make motor test sample, Compressive strength、bending strength and tensile strength shall be according to slag additament, by means of. slag add itament substitutes for cement 40%~60% is most. But slag be able to substitute for cement is too enough, 1ater strength shall be descent.

由本研究可得知海砂拌和的水泥砂浆，其早期抗压强度较高，而晚期强度则有下降的趋势，其中以非标准砂拌和效果最为明显；若以50%海砂替代河砂做为拌和细骨材，其早期抗压强度约上升20%~30%；添加炉石於海砂或河砂、海砂各半的水泥砂浆，其抗压、抗弯及抗拉强度，会随著炉石添加量增加而增加，其中以40%~60%炉石替代量为最佳，但是炉石替代量过高，晚期强度会下降；在相同水灰比状况下以海砂拌和水泥砂浆做比较，以非标准砂拌和有较高的抗压强度，其强度约比标准砂高10%左右。

After coated,the hydration will take place as soon as cement in the composite system contacts with water of the latex. Because the polymer latex is colloid dispersoid,the polymer particles disperse into slurry and absorb on cement,hydrate and other fillers.

涂料涂覆后，复合体系中水泥遇到乳液中的水即发生水化反应，形成一定量的水泥凝胶体；而聚合物乳液本身属于胶体分散体，其中的聚合物颗粒向料浆中分散，吸附在水泥及其水化产物和其它填料的表面。

In addition, this manuscript studies different influence that cements with different SO3 content give sand-cement grout, cement-fly ash binder, cement fly-ash stabilized hoggin and probe the action that SO3 appears in different material system.

此外，本文还通过研究不同SO3含量的水泥对胶砂试块、水泥粉煤灰结合料以及水泥粉煤灰稳定碎石材料的强度性能的影响，探讨SO3在不同材料体系中的作用。

In order to satisfy the needs of the development in modern cement industry, to satisfy the competence of the powder mill which is needed in cement production line , thus ,to do research on the CKP mill and develop it once more .After that ,it can be made to adapt to the cement technique which produces 2500 tons daily .

本课题是为了适应现代水泥工业的发展需求，满足水泥生产线所需要的粉磨能力而对CKP磨的再次开发研究，使之与日产2500吨的水泥工艺相适应。

Erials, such as instable geltime, low stability, poor underwatererosion resistance and so on, and based on the short geltime features of ordinary cement sodium silicate and alkaliactivated salic cementitious materials, an ideal structure model of high performance sodium silicate suspension twoshot groutingmaterial is established. An experiment is undertaken to verify the solidification value of Na+ and watererosion resistance of a grouting material combined with cement and metakaolinsodium silicate. This paper puts forward a compact structure with a dominant ingredient of—Si—Al—H zeolite gel and a minor part of C—S—H by means of IR and SEM microanalysis method.

摘要］ 针对隧道注浆工程用普通水泥水玻璃双液注浆材料存在凝胶时间不稳定、产物稳定性和抗地下水侵蚀性能差等主要问题，结合普通水泥水玻璃快速胶凝和碱激发硅铝质胶凝材料的特点，建立了高性能水玻璃悬浊型双液注浆材料的理想结构模型，并通过水泥复合偏高岭土水玻璃注浆材料的Na+固化性能和抗水溶蚀性能进行了试验验证，结合IR和SEM微观测试分析手段提出其组成结构应是以—Si—Al—H类沸石凝胶物质为主、C—S—H为辅的复合共存密实结构。

In this thesis, high content blast furnace slag and/or phosphorous slag ecological cement was studied. The aim is to increase additive dosage up to 70% or more, and decrease clinker dosage down to 20% or less, as well as ensure that the resulting cement must possess excellent physicomechanical properties and good durability.

本研究的目的是以矿渣和磷渣为代表，将目前生产的矿渣和磷渣水泥中的混合材掺量逐步提高到70％以上，熟料用量减少到20％以下，在确保水泥具有良好物理力学性能和耐久性能的前提下研制高掺量矿渣、磷渣生态水泥。

Thin elastic foundation of cement concrete pavement design theory, in-depth analysis is to arrive at the grass-roots non-uniform bearing broken concrete pavement panels, gnawing edge, the wrong units, as well as the main reason for structural damage produced by taking certain measures to improve the concrete between the road surface and the grass-roots support conditions, and improve durability of the cement concrete pavement and stability.

通过水泥混凝土路面弹性地基薄板的设计理论，深入分析得出基层的不均匀支承是水泥混凝土路面断板、啃边、错台、以及产生结构性破坏的主要原因，通过采取一定措施改善砼路面面层与基层之间支撑条件，提高了水泥混凝土路面的耐久性和稳定性。

Subsequent inspection revealed that many of these lintels have sustained rusting to their surfaces and this is considered to be the cause of the break down of the cement rendered surface.

问题被发现是因为窗楣的部分水泥涂层脱落，在contractor 去掉剩下的水泥涂层后发现原来的窗楣表面已经生锈，这也是导致水泥涂层脱落的原因。

Moreover, this kind repairers suitable temperature range is wide, from 0°C to 35° C, and can be used in the whole year. The cement concrete pavement fast repairer has a long time to be used in construction and is easy to operate, so it can be widely used in road construction.This thesis reports the present development situation of Portland cement concrete pavements in Sichuan Province. It focuses on the investigation of pavement conditions in the northern section of Dajian Road, the Chengdu-Longquanyi section of Chengdu-Chongqing Freeway, and Chengdu-Wenjiang-Qionglai Highway.

论文全面总结分析了四川省水泥混凝土路面的发展现状，重点对大件路北段、成渝高速成龙段、成温邛公路三个路段的水泥混凝土路面破损情况进行了调查，分析了主要的破损类型并进而指出了四川省水泥混凝土路面发展中存在的问题。

In order to widen selective range of coals in cement kiln, in this thesis, the research of ignition characteristics, kinetics and microstructure to different quality coal is carried on, which offer the foundation theoretical for the low quality coal used in New Dry Process kiln craft.
