摘  要：铸余渣主要含有C2S、C3S及少量铝酸盐和玻璃质，粒度小于1mm的铸余渣占比为53.11%，通过10mm过筛可获得41%的铸余渣尾粉。在水泥预粉磨中外掺6%的铸余渣，粉磨过程没有出现“饱磨返料”的现象，表明其易磨性较好，但粉磨产量下降4t/h，因此，单独粉磨铸余渣经济性不佳，需搭配各类混合材共同粉磨。在水泥中外掺6%的铸余渣后各项指标满足GB175—2007《通用硅酸盐水泥》。将铸余渣用于替代28%的磷渣微粉后的强度均有所降低，但后期强度可满足GB/T14902—2012《预拌混凝土》的使用要求。Abstract:ThecastingresiduemainlycontainsC2SandC3S,asmallamountofaluminatesandglass.Theratioofcastingresiduetograinsizelessthan1mmis53.11%,and41%ofthetailingspowdercanbeobtainedby10mmscreeningof.Incastingslagcementpregrindingandgrindingprocesswith6%,no"returnsaturation"phenomenon,showitsgoodgrindability,butthegrindingproductiondeclines4t/hours,soseparategrindingslaghasthepooreconomy,whichneedsallkindsofcollocationmixedmaterialgrindingtogether.Afteradding6%ofthecastingresiduetothecement,theindexesmeetGB175—2007GeneralPortlandCement.Thestrengthoftheslagusedtoreplacethe28%slagpowderhasbeenreduced,butthelaterstrengthstillmeetstherequirementsofGB/T14902—2012ReadyMixedConcrete.

摘 要：地下室超长结构在温差、混凝土收缩等作用下，极易出现裂缝，不但影响工程质量，还影响使用功能。通过对地下室外墙板采用无粘结预应力抗裂施工工艺，克服了温差、收缩等引起的拉应力，达到了控制裂缝的目的。 Abstract: Under the influence of temperature difference and concrete shrinkage, the ultra-long structure of basement can easily crack, which not only affects the engineering quality, but also affects the function. The tensile stress caused by temperature difference and shrinkage is overcome by using non-bonding prestressed anti-crack construction technology for underground and outdoor wallboard, which achieves the purpose of controlling crack.

摘 要：利用自制的简易装置可测试混凝土早期的体积变形，测试数据准确可靠，可以较好的反应混凝土的体积变形趋势，对于体积变形量较大的高强度等级自密实混凝土亦与红外测试装置相差不大，此种测试方法具有广泛的适用性，具有一定的推广价值。测试结果表明，聚羧酸减水剂和膨胀剂对混凝土的收缩有较好的抑制作用。矿粉对混凝土的收缩起促进作用，粉煤灰对混凝土的收缩有一定的抑制作用。 Abstract: The simple homemade device is used to determine the early-age volume deformation of concrete, the accurate and reliable results show that this method could reflect the trend of volume deformation of concrete effectively. For the high-strength self-compacting concrete with large volume deformation, the differences of results between the infrared testing device and the method are small. Therefore, this method could be widely applied and worth a certain of promotional value. The results show that polycarboxylate- superplasticizer and expansion agent have the preferable inhibitory action on shrinkage of concrete. Mineral powder play a role in promoting the shrinkage of concrete, while, the fly ash has a certain of inhibitory action on shrinkage of concrete.

摘 要：在我国在建和待建的核电站中，存在大量的大体块混凝土结构及其他形式的复杂混凝土结构，利用传统的超声波测混凝土缺陷方法测试这些结构的内部缺陷存在一定的困难。针对这种检测需要，设计了一种新型混凝土缺陷测试方法，采用能够向四周空间均匀发射超声波的球形埋置式超声波探头，在结构内部组成阵列布置，相互之间收发超声波信号，或与外部手持式平面超声波探头搭配使用，从而分析混凝土内部的密实度状况。 Abstract: Mass concrete structure and other complex concrete structure are commonly utilized in nuclear power plant under construction and to be built in our country. There are different difficulties to detect the internal defect of these structures with traditional test methods. A new method of concrete defect test was researched which utilized a spherical embedded ultrasonic transducer as the core component. The transducers can be located inside the concrete structure in a preset pattern, and motivate or receive the ultrasonic signal with other transducers around or the traditional transducer handled by test personnel on the structure surface to analyze the compactness situation of concrete inside the structure.
