The experimental results show that these models can express precisely the isotherm hydration heat emission curve of portland cement and the autogenous shrinkage process of concrete prepared with portland cement 实测数据检验结果表明，这2个模型可以用于模拟硅酸盐水泥的等温水化放热曲线，以及用硅酸盐水泥配制的混凝土的自收缩发展过程。
This paper aims at the seriousness of concrete structure crack and presents one of main cause is that concrete early - age ( especially autogenous shrinkage ) become large through the systems academic analysis 本文正是针对混凝土结构工程早期裂缝的严重性，通过理论分析，指出目前混凝土早期收缩(主要自收缩)的变大是造成这种早期裂缝的主要原因之一。
The resultant cosmetical figur and the succeeding prothetic - eyeball movement are rather satisfied ; the disadvantages of synthetic implants such as migration or extrusion of implant , never happened to the autogenous dermis - fat implant in anophthalmic socket 利用此种皮脂植入物可以免除代用眼球植入的种种合并症，诸如代用眼球移位或迸出肌束；外观及眼球运动情形，亦令人满意。
A best substitute of blood vessel has been pursued for a long time . many materials have been tried such as autogenous artery or vein , artif icial material , biomaterial and et al , but no ideal substitute was found until now 人们长期以来一直在寻找一种血管的最佳替代物，尝试了自体动静脉、人工材料、生物材料以及人工材料与生物材料复合等多种方法，但这些方法都或多或少存在着一些不足。
After bfs is put into high strength superplasticized expansive concrete ( substituted for cement ) , autogenous shrinkage does n ' t appear in 1 day standard curing , and e2 in 14 day ' s age is higher than that of high strength superplasticized expansive concrete without bfs in the same age 高强流态膨胀混凝土掺入磨细矿渣(等量替代水泥)后，标准养护1天未出现自收缩， 14天的限制膨胀率明显高于未掺磨细矿渣的高强流态膨胀混凝土的对应值。
In the dam foundation restraint area , mgo can be mixed into concrete to prevent dam longitudinal crack . research on autogenous volume change of rcc mixed with mgo , and research on thermal stress compensation of darn foundation prove that rcc mixed with mgo plays a role in dam crack control 在材料措施方面，深入研究高碾压混凝土坝基础约束区采用外掺mgo措施，利用其微膨胀性能补偿坝体降温过程中产生的温度应力，以防止大坝纵向裂缝的发生。
We research the causes of concrete cracking , develop the high performance anti - cracking additive , optimize the concrete mix and construction techniques , increase the stability of concrete volume by shrinkage compensation , enhance splitting tensile strength , and can meet demand of high workability of fresh concrete . . in the study , a thorough investigation of this problem is made from all points of view , with the aid of various modern measurement & testing technology and different theories & methods in surface physical chemistry , structural chemistry , solid - state chemistry , composite materials , fracture mechanics , etc . our research results have shown that the various shrinkage of concrete cause concrete cracking in building engineering , such as autogenous shrinkage , dry shrinkage , temperature shrinkage , plastic shrinkage , carbonized shrinkage , etc 目前，解决混凝土开裂的方法是综合的，我们调查研究了混凝土开裂的原因，开发研制了高性能抗裂外加剂，优化混凝土的设计和施工方法，并通过补偿收缩达到混凝土体积稳定，提高抗裂强度，满足混凝土拌和物高工作性能的要求。本研究采用多种测试技术，应用表面物理化学、结构化学、固体化学、复合材料学、断裂力学等多学科的理论与方法，从不同的角度进行深入的研究和探讨。通过调查研究建筑工程中出现的混凝土开裂、渗漏问题，发现混凝土在非荷载作用下开裂主要是由混凝土的自收缩、干燥收缩、温度收缩、塑性收缩、碳化收缩等各种收缩变形引起的。
Temperature control and crack prevention of concrete - the simulation analysis characteristics of dams construction with mgo concrete , the theory apply " equivalent time " to the model for computing autogenous volumetric change of concrete which be relate to temperature history . it makes computing autogenous volumetric change of concrete be realized at case of arbitrary temperature history , so the problem puzzled engineer over a long period of time may be dispelled 针对温控防裂的一项新技术?外掺mgo混凝土筑坝技术的仿真计算特点，提出了应用“有效时间”理论，来考虑自生体积变形与温度历史有关的膨胀模型，使长期以来困绕工程界有关外掺mgo在任意温度历史下产生的膨胀变形的应力补偿计算成为可能。
