【摘要】：随着人们生活水平的不断提高,人们对蔗糖和酒精的需求不断增加,同样糖蜜乙醇废液的排放量也在不断增加。广西的蔗糖产量居全国第一,其副产物糖蜜乙醇废液如何无害化、资源化的处理成为阻碍广西区某些大型城市发展的枷锁。国家发布了《关于印发进一步做好禁止使用实心粘土砖工作的意见的通知》明令“禁粘”“禁实”以及大力发展新型建筑材料的背景下,糖蜜乙醇废液页岩砖砌体研发不仅符合国家政策的要求,而且对广西区大中城市的发展起到促进的作用。本次实验主要对糖蜜乙醇废液页岩砖的基本力学性能—抗剪性能和剪压复合抗剪进行实验分析。为今后糖蜜乙醇废液页岩砖形成地方标准提供数据,进而促进糖蜜乙醇页岩砖在广西区大面积推广。根据试验的结果分析有:(1)对试验所得的抗剪强度数据进行回归处理,可得出糖蜜乙醇废液页岩实心砖和多孔砖砌体的沿通缝抗剪强度平均公式。与现行2011规范规定的抗剪强度公式相比,糖蜜乙醇废液页岩砖砌体的抗剪性能有所提升。与普通的页岩砖相比强度提升的原因在于:糖蜜乙醇废液页岩实心砖表面较粗糙;砂浆的粘结力强。糖蜜乙醇废液页岩多孔砖强度提升原因为:多孔砖砌体销键的存在对通缝抗剪至关重要;多孔砖砌体在销键抗剪和粘结抗剪的协同作用下,抗剪强度大大提升。(2)分别以纯剪强度和抗压强度对试验所得的剪压抗剪强度数据进行回归处理,得出糖蜜乙醇废液页岩实心砖和多孔砖砌体的剪压复合抗剪强度平均公式。从试验数据可以看出:在压力和剪力共同作用下,两种砖砌体的受力曲线的走势大致相同;从整体来讲糖蜜乙醇废液页岩实心砖的剪压复合抗剪强度高于糖蜜乙醇废液页岩多孔砖。
[Abstract]:With the continuous improvement of people's living standards, people's demand for sugar and alcohol is increasing, and the amount of molasses ethanol waste liquid is also increasing. Guangxi ranks first in sugar production in China. The by-product molasses ethanol waste liquor how harmless, Resource-based treatment has become a yoke hindering the development of some large cities in Guangxi. The State issued the notice on issuing and issuing opinions on further prohibiting the use of solid Clay Brick. In the context of the development of new building materials, The research and development of molasses ethanol waste shale brick masonry not only conforms to the requirements of national policy, This experiment mainly analyzes the basic mechanical properties of molasses ethanol waste shale brick-shear resistance and shear pressure composite shear resistance. For the future molasses ethanol. Local standards for the formation of waste shale bricks provide data, In order to promote the popularization of molasses ethanol shale brick in a large area in Guangxi, according to the analysis of the results of the experiment, the shear strength data obtained from the experiment were treated by regression analysis. The average formula of shear strength along the pass joint of solid shale brick and porous brick masonry with molasses ethanol waste liquid can be obtained. The shear resistance of molasses ethanol waste shale brick masonry has been improved. Compared with ordinary shale brick, the reason of strength increase is: the surface of molasses ethanol waste shale solid brick is rough; The strength of molasses ethanol waste shale porous brick is enhanced by the following reasons: the existence of the pin bond of porous brick masonry is very important to the shear resistance of the through joint, and the porous brick masonry is under the synergistic action of the pin bond shear resistance and the bond shear resistance. The shear strength is greatly improved. (2) the data of shear strength obtained from the test are regressed with pure shear strength and compressive strength, respectively. The average formula of shear-compression composite shear strength of solid shale brick and porous brick masonry with molasses ethanol waste liquid is obtained. From the experimental data, it can be seen that under the combined action of pressure and shear force, the force curve of the two brick masonry is roughly the same; On the whole, the shear strength of solid brick is higher than that of molasses ethanol waste shale brick.
