Description
Technical field
The present invention relates to a kind of measurement mechanism and measuring method, be specifically related to a kind of measurement mechanism and measuring method of concrete viscosity.
Background technology
The measuring method of fresh concrete rheological property by the theory that famous scholar Bingham proposes, will be measured sticking and these two parameters of plastic viscosity of concrete yield stress at least.Foreign scholars are in order to measure this two parameters; Existing traditional viscosity apparatus many improvements have been done; Famous scholar G.H.Tattersall and his students in order to measure concrete rheological parameter, have designed multi-form paddle as far back as the seventies in last century.The scholars that go together in Japan and Europe also change the structure that has viscosity apparatus now, have done a large amount of experimental works, and still, the laboratory report and the correlation curve of the relevant concrete flow variable element of various countries scholar differ greatly so far, and the conclusion of laboratory report is very inconsistent.Its main cause is that the paddle of existing flow graph is prone to make aggregate to separate with slurry in agitation; Can not make concrete form the laminar condition of stable homogeneous; Problems such as the measurement of shearing moment is not really accurate; And, limit its widespread use at present because concrete rheological appearance apparatus structure is complicated, cost is high.
Summary of the invention
The present invention for solve the present invention for solve existing flow graph, when viscosity apparatus is measured the concrete flow variable element; Be prone to make aggregate to separate with slurry; Can not make concrete form the laminar condition of stable homogeneous; The problem that the measurement of shearing moment is not really accurately, apparatus structure is complicated, cost is high, and then a kind of measurement mechanism and measuring method of concrete viscosity are proposed.
The present invention addresses the above problem the technical scheme of taking to be: the present invention includes container, steel cylinder, pallet, platen, container cover and electronic scales; Pallet is arranged on the bottom surface of container intracavity; Platen is arranged on the vessel port place of container; The center pit of pallet is passed in the lower end of steel cylinder, and the lower end surface of steel cylinder contacts with the bottom surface of container intracavity, and the upper end of steel cylinder is passed the center pit of platen, the center pit of container cover from the bottom to top successively; The upper end of steel cylinder is connected with the lower end of electronic scales through pin, and the lateral wall of steel cylinder is provided with screw thread.
The concrete steps that the present invention measures concrete viscosity are following:
Step 1, pallet is placed on the bottom surface of container; Insert in the center pit of pallet the lower end of steel cylinder; And the lower end surface that guarantees the steel cylinder contacts with the bottom surface of container intracavity, in container, fills fresh concrete, fills afterwards with platen the fresh concrete compacting; The covered container lid, the center pit that platen and container cover are passed in the upper end of steel cylinder is connected with the lower end of electronic scales;
Step 2, slow rotation hand wheel, electronic scales shows pulls out the suffered frictional resistance of steel cylinder from fresh concrete, and the steel cylinder weight that electronic scales shows in the process greatest measure deducts the steel cylinder that moves up is the friction force of being surveyed;
Step 3, choose the standard flow (like the castor-oil plant wet goods) of a known-viscosity η; In container, fill standard flow; Repeating step one is measured with step 2 and from standard flow, is pulled out the suffered friction force f of steel cylinder; The ratio K of the viscosities il of standard flow and friction force f is for demarcating constant, i.e. K=η/f;
Step 4, multiply by the demarcation constant K value that obtains in the step 3, be concrete viscosity with concrete friction value measured in the step 1.
The invention has the beneficial effects as follows: the present invention is simple in structure; Easy and simple to handle; Can accurately measure concrete viscosity numerical value; When having overcome existing flow graph, viscosity apparatus measurement concrete flow variable element, the paddle of flow graph can not make concrete form laminar condition stable, homogeneous, the inaccurate problem of the measurement of shearing moment.
