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。

A1l the thick adsorption layer,large space steric hindrance,thick solvate layer and stable ξ-potential of ASP adsorbed on cement particles resist the flocculation of cement particles.In addition the early stage hydration of cement is restrained because the—OH ,—NH2 in ASP can suppress the formation of hydrated products such as C-S-H ,Ca2 and ettringite crystals through forming unstable complex compound with Ca2+.So ASP has excellent plasticity-retention capability of concrete.

由于ASP在水泥颗粒表面的吸附层较厚、空间位阻较大、溶剂化层较厚及ξ-电位较稳定等原因，阻碍了水泥颗粒间的凝聚；同时由于ASP含有的—OH，—NH2等官能团与水化产生的Ca2+形成不稳定的络合物，抑制了水化产物C-S-H，Ca2和钙矾石等结晶体的形成，从而抑制了水泥的早期水化，故ASP具有良好的保塑性能。

The old asphalt mixture being dealt with cement is a cold in-place recycling method. The mechanism is that the crushed asphalt mixture and lime soil are reused and is stabilized by cement additive. So the material can be applied in base and subbase course such as cement stabilized aggregate.

利用水泥处治废旧沥青路面材料属于沥青路面冷再生的范畴，其再生机理是将加工破碎的废料(包括废旧的沥青混合料和部分灰土基层)重新利用，经过水泥进一步的稳定作用，形成与水泥稳定级配粒料类似的基层和底基层材料。

The Bulk-cement Delivery Tank Truck is not only the vigorously promoted China's main cement transport bulk carriers, but also the main instrument to delivery the cement in the cement of oil and gas wells, the bulk transport can be greatly save the resources, reduce the damage to the environment and reduce air dust pollution, having great strategic significance to the development of our national economy.

气动下灰车是我国大力推广水泥散装运输的主要运载工具，也是有气井固井作业时水泥运载和输送的主要工具，水泥的散装运输可以大大节约资源，减少对环境的破坏，减少空气中粉尘污染，对我国国民经济的发展具有重大的战略意义。

When mixed into the same carbon fiber quantity is 1.0%, differ age material's AC impedance chart is discrepancy very much, along with to hydrate age's add, C-S-H gel isa great deal of form, the solution resistance at the concrete is gradually aggrandizement, the carbon fibre of here qua transmit electricity quality disperse would leading effect of conductance, along with the add of exterior load, the transmit electricity quality of concrete is almost nothing change, till breakage, resistance change rate tempestuousness add, and that the resistance change rate along with inside stress linearity add of corbon fibre concrete in elasticity phase, when near peak value load, resistance rate just gradually add, indicate the test sample would be about to breakage.

当碳纤维体积掺量同为1.0%时，不同龄期材料的交流阻抗谱相差很大，随着水化龄期的增长，C-S-H凝胶大量形成，水泥基材料中的溶液电阻逐渐增大，此时作为导电性分散相的碳纤维将起电导的主导作用。随着外部荷载的增加，基准水泥基材料的导电性几乎无变化，直到破坏时，电阻变化率剧烈增大，而碳纤维水泥基材料在弹性阶段其电阻变化率随内部应力线性增加，当接近峰值荷载时，电阻率才逐渐增大，预示试件即将破坏。

A new type of hydraulic pulse vibration generator installed at bottom of casing strings was developed.

研制了新型水力脉冲振动注水泥装置，该装置安装在套管底部，在注水泥过程中产生水力冲击作用于套管、水泥浆和钻井液，通过消除气泡、清除泥饼、提高顶替效率和水泥石强度来提高水泥胶结质量。

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.

On closer examination, though, this is not a vote for multilateralism but just the opposite.

仔细审视后我们发现，这并非是对多边主义投出的赞成票，而是恰好相反。
