Study On The Shear Property Of Molasses Alcohol Waste Liquid Of Shale Brick

With the continuous improvement of people’s living standards, people demand for sugar and alcohol are also on the increase, the same molasses ethanol wastewater emissions are increasing year by year. The sugar output of Guangxi province ranked first in the country, and the by-product molasses alcohol waste liquid to harmless treatment, recycling has become the obstacle of Guangxi District, some large city development shackles. The state has issued "on the issuance of further prohibit the use of solid clay brick work of the views of the notice" clearly "ban stick" "cut" and the development of new building materials in the context of molasses ethanol wastewater, shale brick masonry development not only in line with national policy requirements, but also for the development of large and medium-sized city Guangxi district plays a promoting role. This experiment mainly of molasses ethanol wastewater the compressive the basic mechanical properties, shear strength and shear compression composite shear experiment analysis. To provide data for future waste molasses ethanol liquid shale formation of local standards, and then promote the molasses ethanol shale brick in large area of Guangxi region.Based on the test results analysis:(1) The anti shear strength of the regression of experimental data, the waste liquid of molasses ethanol shale hollow brick and porous brick masonry cracks along the shear strength formula of average. With the current rules and regulations of 2011, compared to the shear strength formula of molasses alcohol waste liquid confined shale brick masonry shear performance improved. Compared with the ordinary shale brick intensity ascend the reason: the molasses alcohol waste liquid solid brick shale surface is rough; the he mortar bond strength. Molasses alcohol waste liquid shale strength of porous brick improve reason is: the existence of the porous brick masonry pin key to pass joint shear is essential; Porous brick masonry in the key of shear and bond shear under the synergy of shear strength enhanced greatly.(2) Pure shear strength and compressive strength, respectively, to test the shear strength data regression, molasses alcohol waste liquid shale solid brick and porous brick masonry shear composite shear strength formula of the average. As can be seen from the test data: under the effect of pressure and shear force, force the shape of the curve of two kinds of brick masonry are roughly the same; From the overall molasses alcohol waste liquid solid brick shale shear composite shear strength higher than that of molasses alcohol waste liquid shale porous brick.
