Problems solved by technology

[0006] The purpose of the present invention is to provide a device and method for hydraulically measuring the demoulding performance of concrete to solve the problem that the existing method for evaluating the demoulding performance of concrete is not accurate enough, and the operation is time-consuming and laborious. Effectively and completely separated from the concrete test mold, the precise control and monitoring of air pressure changes cannot be realized. In addition, the equipment used is complicated and expensive.

specific Embodiment approach 2

[0035] Specific implementation mode two: combination figure 1 , figure 2 and image 3 To illustrate this embodiment, first place the concrete mold 2 vertically, screw its lower end with the first installation cover 1, and connect the internal thread of the first through hole 8 with the external thread of the middle piece 4, and assemble the concrete mold 2 Add a layer of plastic film to the bottom of the concrete mold 2, apply a release agent on the inner wall of the concrete mold 2, then fill the concrete mold 2 with fresh concrete 12 that meets the requirements of the standard, and place it under standard curing conditions for at least 24 hours of maintenance; After completion, after the upper end of the concrete mold 2 is screwed to the second installation cover 3, the concrete test mold 2 is placed horizontally, and the first installation cover 1 is unscrewed so that the distance between the first installation cover 1 and the lower end of the concrete mold 2 is 5 ~ 10mm...

Embodiment 1

[0038] Embodiment one: the concrete mold 2 is a steel pipe, its inner diameter is 200mm, the radius R=100mm, the height H is 200mm, and the diameter of the first through hole 8 is 50mm. First, the concrete mold 2 is vertically placed, and its lower end is connected with the first installation The cover 1 is threaded, the internal thread of the first through hole 8 is connected with the external thread of the middle piece 4, and a layer of plastic film is added to the bottom of the assembled concrete mold 2 to ensure that the concrete 12 does not enter the first hole in the middle piece 4. A through hole 10 and isolation concrete 12 are in contact with the first installation cover on the end face, then apply a release agent on the inner wall of the concrete mold 2, then fill the concrete mold 2 with fresh concrete 12 that meets the requirements of the standard, and place the Curing under standard curing conditions for at least 24 hours; after the curing is completed, the upper e...

Abstract

The invention discloses a device and a method for hydraulically measuring concrete demoulding performance. In an existing way of effectively and completely separating a test specimen from a concrete testing mould manually through an inflating pump, precise control and monitoring of air pressure change cannot be achieved, and equipment used for cooperating with the method is complicated and is highin cost. In the device, a first mounting cover and a second mounting cover are vertically arranged in parallel; a concrete mould is arranged between the first mounting cover and the second mounting cover; the two ends of the concrete mould are detachably connected with the first mounting cover and the second mounting cover; concrete is arranged inside the concrete mould; one end of a middle component runs through the first mounting cover and is communicated with the concrete in the concrete mould; the other end of the middle component is communicated with an oil outlet of a hydraulic pump through a connecting pipe. The device is reasonable in structural design, timely, accurate and effective in measurement result and convenient to operate. The method is convenient to operate and easy to control. The device and the method are used for measuring the concrete demoulding performance.

Description

technical field [0001] The invention specifically relates to a device and method for hydraulically measuring the release performance of concrete. Background technique [0002] At present, my country has formulated the release agent standard JC / T949-2005 for concrete products. The quality evaluation index of the release agent mainly considers homogeneity and construction performance. Homogeneity refers to density, viscosity, PH value, solid content or Stability and construction performance refer to drying film forming time, mold release performance, water resistance, corrosion effect on steel molds, limit service temperature or other indicators. Concrete release agent refers to a substance applied on the construction formwork before concrete pouring, so that the formwork will not stick to the concrete surface after pouring, easy to remove the formwork, and will not affect the smoothness of the concrete surface. Its main function is to form a film on the surface of formwork an...
