Description

Quick accurate testing arrangement of coal-based solid useless filling slurry slump and expansibility

Technical Field

Background

Slump is a measure method and index of concrete workability, coal-based solid waste is an accessory product of processes of coal exploitation, processing, combustion, conversion and the like, and mainly comprises coal gangue, fly ash, a boiler, desulfurized gypsum, coal gasification ash slag, coal liquefaction residues and the like, in a coal-based solid waste proportioning experiment, a micro slump and expansion fluidity experiment is usually carried out on a plurality of groups of filling material proportioning schemes obtained by a response surface method optimization and fitting module, in the study, the micro slump and expansion test is used for representing the fluidity of the filling material, and slump values are used for describing the initial fluidity of the filling material and can reflect the cohesive force and friction resistance of slurry. In the coal-based solid waste proportioning experiment, the slump testing method comprises the following steps: filling slurry into a trumpet-shaped slump barrel with an upper opening of 100mm, a lower opening of 200mm and a height of 300mm, uniformly beating 25 downwards from outside to inside along the barrel wall by using a rammer after filling, and trowelling after tamping. Then the slump barrel is lifted up at a constant speed along the vertical direction, the slump phenomenon is generated by the filling slurry due to the dead weight, the height of the highest point of the filling slurry after slump is subtracted by the height of the barrel (300 mm), the slump is called slump, and if the difference is 10mm, the slump is 10. When the filler slurry slump is greater than 220mm, the filler slurry spread can be measured. In the coal-based solid waste proportioning experiment, the expanding degree test method comprises the following steps: after the slump barrel is lifted up at a constant speed along the vertical direction, measuring two diameters of the expansion surface of the filling slurry after slump, which are mutually perpendicular, by using a measuring ruler, and taking the average value of the two diameters as the expansion value.

In summary, in the coal-based solid waste proportioning experiment, the slump and the expansion degree of the filling slurry are mostly required to be measured manually by using various testing devices, and the steps are complicated and the precision is not high. When the manual work is inserted and is smashed to fill the ground paste in the slump section of thick bamboo with the ram, if it is inhomogeneous and the stirring time overlength can cause the aggregate water absorption great to lead to measuring error great, when the manual work is mentionedly with the slump section of thick bamboo, if can not perpendicular steady mentioning slump section of thick bamboo, then fill the ground paste and can receive horizontal and torsion effect, also can cause slump loss, consequently manual measurement and calculate slump and extension not only operate inconvenience, increase staff's work burden, and operating efficiency is lower moreover, testing arrangement also inconvenient dismantlement and washing.
