Adding silica sand to cement whose temperature ranges from 110～150℃or maintaining it in 110℃about three days, cement can form the fiber C5S6H5. After temperature above 150℃, it form thick needle C6S6H which can to some extent effectively curb the high-temperature recession of cement strength.

在水泥中加入硅砂时，在110～150温度范围内，或110℃养护时间超过3天，水泥石中分别出现了由纤维针状结晶C5S6H5，温度超过150℃后，又出现粗大针状结晶硬硅钙石C6S6H，这两种产物在一定程度上有效地抑制水泥石强度的高温衰退现象。

The test results indicate that ground water-granulated blast furnace slag in cement can help to enhance the compatibility between superplasticizer and cement while addition of fly ash or zeolitewill lead to reduction of fluidity and fast loss of fluidity of cement pastes.

结果表明：水淬高炉矿渣有利于改善减水剂与水泥的适应性，而掺粉煤灰和沸石则会导致减水剂塑化作用的降低，而且浆体流动性损失也有增大趋势。

In this paper, a kind of limestone compound active agent, which can greatly increase the strength of blended limestone cement was introduced. For example, 52.5 MPa clinker can generate 42.5 MPa cement containing 30% limestones by mass when LCAA was used in the cement.

CO2 and H2S exist in the hydrocarbon zone and foramtion water,as the accompany gases of petroleum and nature gaso or components of formation water,which will cause corrostion to the cement sheath under certain conditions of humidity and pressure.It will decrease the cement sheath's alkalinity,which results in the decrease of cement sheath's strength,permeability increase,and places a premium on fluid channeling and borehole wall sloughs accident in plastic formation,shortening the oil- gas well's production lifetime and giving rise to tremendous ecomonic losses.

CO2和H2S作为石油和天然气的伴生气或地层水的组分存在于油气层或地层水中，在一定的湿度及压力条件下会对固井水泥环产生腐蚀作用，从而降低水泥环的碱性，使水泥环强度下降，渗透率增大，并诱发流体窜流、塑性地层井壁跨塌等事故，从而缩短油气井的生产寿命，造成巨大的经济损失。

Each time after putting to (the instrument with the set of Yamshidi-Nadel provided by Kypho of America for injection of bone cement into the vertebrae; each putting could contain about 1.5 mL bone cement) inject bone cement into the vertebrae, the pressure P was not very high, with 500 kPa bar below for majority and the effect caused showed a significant statistical difference (P.01). Whereas, the pressure within the area of the vertebral P value was not high either, the majority was 10.00 Unit lower, which also led to the effects of significant difference (P.01). Both two states showed partial distribution. After making the statistical analysis to the casual two puttings between the first, second, third and fourth putting of each vertebrae, there existed the general differences. The differences were also found between other puttings (a.0083) on the statistics basis apart from between the first and second and between the third and fourth.

结果 每个椎体的椎体成形术均达到临床评价要求，每次推杆（美国Kypho公司提供标准椎体成形术中Yamshi-Nadel套系中推注骨水泥入椎体的器具，每具推杆可容纳骨水泥约1.5mL）推注骨水泥入椎体时所产生的椎体内的压力P不是很高，多数在0.50 bar以下，其所导致的效应具有显著的统计学差异(P.01)，而每次推杆推注骨水泥入椎体时的椎体内压力面积值P也不是很高，多数在10.00 Unit以下，其所导致的效应具有显著的统计学差异(P.01)，两者均呈偏态分布；而且，对每例椎体的第一、二、三、四杆之间两两予以统计学上的分析，在总体存在差异有统计学意义的基础上还发现除第一和二杆、第三和四杆之间外，其他各杆之间存在着差异(a.0083)。

AbstractObjectives1 Correlate bone mineral densityto vertebral compressive strengths.2 Consummate the technique for percutaneous polymethylmethacrylate vertebroplasty and observe the pattern of PMMA imaging distribution.3 Determine the strength and stiffness of osteoporotic with or without vertebroplasty with PMMA bone cement.4 Correlation of BMD,insertion torque and pull-out strengths of pedicle screws.5 Ascertain whether augmentation with PMMA bone cement can enhance pedicle screw fixation in the osteoporotic spine.6 Ascertain whether augmentation pedicle screw fixation with PMMA bone cement can enhance the stability of unstable thoracolurner burst fractures of osteoporotic spine.
