This paper, aiming at the weak points of the low early strength and the slow setting and hardening of portland fly-ash cement , according to the forming mechanism of cement clinker minerals, cement clinker minerals are choosen, fly ash is used as a substitute of clay as raw materials, early and high strength type cement clinker has heen developed, the amount of alit in the clinker is very high.

本文针对粉煤灰水泥早强低，凝结硬化慢等缺点，根据水泥熟料矿物的形成机理，用粉煤灰代替粘土作原料，对熟料矿物进行优化组合，成功地研制出了一种高硅酸三钙的早期强度高的水泥熟料，这种熟料可掺入30％一40％粉煤灰，生产出425R型粉煤灰水泥。

On the basis of the comprehensive study and analysis of the literatures concerning the mechanism and properties of CCWC, the substances that can react with anhydrate or hydration products and other supplementary ingredients were selected, and variety of experiments were conducted by means of cross experimental design. The effects of chemical composition and dosage of raw materials, curing condition, and chemical admixtures on waterproofing ability were tested and analyzed.

本文在对水泥基渗透结晶型防水材料的作用机理和应用性能分析研究基础上，选择能与水泥混凝土中未水化水泥及部分水化产物反应的活性物质和其它的辅助成分，利用正交设计方法，研究不同组分对涂料防水性能的影响，并详细分析了原料化学成分、掺量及养护条件等参数的变化对涂料渗透结晶性能的影响，研制成功了一种以硅酸盐水泥为基础的水泥基渗透结晶型防水涂料—GT防水涂料。

A study on pore structure of mortar specimens from high belite cement, Portland cement and medium-heat cement was carried out and the structure of cement paste of HBCC was investigated with the help of theory and test method for high molecular compounds.

本文对高贝利特水泥、硅酸盐水泥、中热水泥胶砂的孔结构进行了观察分析，并借鉴高分子学科的理论和试验方法，初步探讨高贝利特水泥混凝土中C-S-H凝胶的结构。

In cement, the world's biggest producer, France's Lafarge, bought Orascom Cement of Egypt, and the third-largest, Mexico's Cemex, purchased Rinker, a big Australian rival.

在水泥行业，最大的水泥制造商法国Lafarge公司，收购了埃及的Orascom水泥公司；第三大水泥企业墨西哥cernex，收购了澳洲的重量级竞争对手Rinker。

It is higher demand of slip casting engineering of imperious curtain of municipal refuse landfill , because its coarse grain and higher sweating rate when its concretion and its antacial poor stability of cement cumulates, its difficult to meet the design specification of antiseepage by the onefold cement slip casting.

城市垃圾卫生填埋场对防渗帷幕注浆的要求较高，单纯的水泥注浆，由于水泥颗粒较粗、水泥浆液凝固时的析水率较高、水泥固结体抗酸稳定性较差，很难满足设计对防渗的要求。采用粘土水泥固化浆液相关性能均能满足垃圾填埋场防渗帷幕的要求。

The results show that a proper air - entraining agent to be added not only can increase strength of cement polystyrene board effectively, but also decrease its density. The fly ash to be used instead of part of cement can save cement consumption and lower production cost under the prerequisite to ensure the property of cement polystyrene board.

结果表明：适量引气剂的加入不仅可有效提高水泥聚苯板强度，还可降低密度；采用粉煤灰代替部分水泥可以在基本保证水泥聚苯板性能的前提下，节省水泥用量，降低生产成本。

Application of ICHA cement in goat lateral tibial plateau compression fracture: The prevalence and degree of fracture subsidence was significantly reduced at the two time-points in the defects treated with ICHA cement compared with those filled with autograft. X-ray show the cement resorbed rapidly. There were no significantly differences in fracture stiffness between the two treatment groups at the two time-points.

ICHA水泥在羊外侧胫骨平台压缩性骨折中的应用：大体观察发现3个月和6个月两个时间点的自体骨组关节面出现塌陷的程度和数量均较骨水泥组严重。X光片示自体骨组3个月时已基本愈合，6个月时完全愈合，骨水泥组3个月时水泥被吸收分割成几块，边缘模糊，6个月时大部分吸收殆尽。

The results show that superplasticizer has effect on clinker grinding in varying degrees,which depend on the amount of superplasticizer and the property of clinker、The compatibility of the same clinker with different superplasticizers and that of the same superplasticizer with different clinkers are diferent.

结果表明，高效减水剂对水泥熟料具有不同程度的助磨作用，作用的大小与减水剂掺量及熟料自身物料特性有关；高效减水剂与水泥熟料之间存在相容性问题，同一种水泥熟料与不同减水剂、同一种减水剂与不同水泥熟料之间的适应性不同。
