摘要：对一种粉砂土水泥土进行配合比设计，该水泥土仅以当地滩涂粉砂土作为骨料，不使用砂石等粗骨料。采用三因素三水平的正交试验法对其配合比进行试验，通过极差和方差分析，得到土胶比、水胶比、水泥量对水泥土坍落度和28d抗压强度的影响程度；进行了回归分析，建立了线性回归方程；结合相应曲线，得到相应情况下的最优配合比。 Abstract: A kind of silty sand concrete mixure ratio is designed. This concrete selects the silty sand on local beaches as fine aggregate of concrete. Three factors of soil cement ratio, water cement ratio and cement dosage are considered in an orthogonal test with three levels adopted in three factors. On the basis of range and variance analysis of the test results, the influence of different experimental factors on the 28d compression strength and the slump is studied. A series of regression relationships of 28d compression strength and the slump with regression software are derived. According to the corresponding curves, the optimal mixure ratio is obtained.

摘要：结合工程实例，以某大型超市楼盖为研究对象，利用有限元软件YJK进行结构分析与设计，通过比较薄壁箱体现浇混凝土空心楼盖和现浇混凝土实心楼板两种楼盖体系在荷载、跨度等相同参数条件下的经济指标，提出薄壁箱体现浇混凝土空心楼盖体系的适用范围。通过对两种楼盖结构体系在相同条件下的混凝土和钢筋用量的分析比较中可以得出：只要结构的跨度大于9m，无论所受活荷载大小，薄壁箱体现浇混凝土空心楼盖结构体系均会具有更好的经济性能，且其经济性会随着结构跨度和荷载的增加而更加明显。 Abstract: Combining with the project example，a large supermarket floor is taken as the object of research, and the finite element software YJK is used to simulate and analyze. The applicable scope of cast-in-situ concrete hollow floor with thin-wall core box is proposed by comparing economic indicators of the cast-in-situ concrete hollow floor with thin-wall core box and cast-in-situ concrete solid slab under the same parameters such as load and span. Based on comparative analysis of the amount of concrete and steel of the two floor structure system under the same conditions, it can be concluded that when the structural span is more than 9m, no matter what size of the live load, the cast- in-situ concrete hollow floor with thin-wall core box will have better economic performance, and this kind of economic growth will be more apparent with the increase of structural span and load.

摘要：采用物理发泡方式制备了不同密度等级泡沫混凝土，研究了泡沫混凝土经高温热处理后的性能和结构演化。结果表明：随热处理温度提高，各密度泡沫混凝土的质量损失增加、抗压强度降低、吸水率增加，且均在800℃时趋于一致。密度等级对高温热处理后的泡沫混凝土性能影响较为明显。在400℃以前，300～400kg/m3密度等级的泡沫混凝土质量和抗压强度损失更大，吸水率增加更多；在600℃温度处理后，各密度等级的泡沫混凝土基本性能均出现明显下降；在800℃时，各密度等级泡沫混凝土基本性能趋于一致，质量损失为20%左右，质量吸水率为65%～70%，基本丧失抗压强度。Abstract：Foamconcretewithdifferentdensitywasprepared,thepropertiesandstructuralevolutionoffoamconcreteafterhightemperatureheattreatmentwerestudied.Theresultsshowedthatthemasslossincreases,thecompressivestrengthdecreases,thewaterabsorptionincreaseswiththeincreasingofheattreatmenttemperatureandallthesetendtobeconsistentat800℃.Theeffectofdifferentdensityontheperformanceoffoamconcreteafterhightemperatureheattreatmentisobvious.Themasslossandwaterabsorptionincreasehigher,thecompressivestrengthdecreasehigherwhenthedensityoffoamconcreteis300～400kg/m3under400℃.Thebasicperformanceofdifferentdensityoffoamconcretedecreaseobviouslywhentheheattreatmenttemperatureis600℃.Allthesebasicperformancetendtobeconsistentat800℃,themassloseis20%,waterabsorptionis65%~70%andthecompressivestrengthisalmostzero.

摘要：在已有单掺钢纤维和合成纤维混凝土的研究基础上，研究了聚乙烯醇纤维（PVA）和钢纤维混杂，及两种不同参数钢纤维混杂的增韧、增强效果。结果表明，相对于单掺纤维，不同纤维混杂可使混凝土的弯曲强度及弯曲韧性明显提高，荷载作用下混凝土弯曲荷载-挠度曲线的下降段明显变缓，应变硬化现象更为明显，混杂纤维可以产生协同增强效应。 Abstract: Based on the research of existing single steel fiber and synthetic fiber reinforced concrete，the effect of PVA fiber, steel fiber hybrid toughening effect and two different parameters of hybrid steel fiber on toughening， reinforcing were studied. The results showed that different characteristics of the fiber mixed together can significantly improve the bending strength of concrete and flexural toughness when compared with the single fiber，the flexural load-deflection curves of concrete falling speed is slow and the strain hardening phenomenon is more obvious，hybrid fiber can produce synergistic effects.
