Problems solved by technology

[0009] 1. When the unconfined test piece is formed, the pressure is high, and the test piece is in close contact with the inner wall of the cylindrical test mold. Under the push of the external force, the test piece and the inner wall of the test mold produce friction, which greatly disturbs the test piece and affects the actual strength.
[0010] 2. Delayed demoulding can reduce strength loss, but there is still disturbance phenomenon, and there is still loss of strength
[0011] 3. Delayed demoulding reduces test efficiency, and requires more test molds to meet the requirements of test frequency

Embodiment approach 1

[0045] see Figure 1 to Figure 7 As shown, an inorganic binder unconfined compressive strength sleeve mold device proposed in the embodiment of the present invention includes an outer mold 1 and an inner mold 2 that can be detached laterally, and the inner mold 2 is cooperatively connected inside the outer mold 1. The upper and lower parts of the inner mold 2 are respectively provided with upper and lower pressure pads 3 and 4 .

[0046] When the mold set device is in use, the inner mold 2 is first assembled inside the outer mold 1, and the lower pressure cushion block 4 is installed under the inner mold 2, then the inorganic binder is installed inside the inner mold 2, and then the inner mold 2 is placed above the inner mold 2. Install the upper pressure pad 3, at this time, the upper and lower pressure pads 3 and 4 are respectively located at the upper and lower positions of the inorganic binder, so that the upper and lower pressure pads 3 and 4 apply pressure to the middle ...

Abstract

The invention discloses a cover mould device with unconfined compression strength for an inorganic binder and a method. The cover mould device comprises an outer mould and a crosswise detachable inner mould, wherein the inner mould is connected with the interior of the outer mould in a matching manner, and upper and lower pressing cushion blocks are respectively arranged above and below the interior of the inner mould. The cover mould device is used for overcoming the defect that a tested piece and the inner wall of a tested mould are subjected to jacking, pushing and frictional disturbance during a de-molding process of the tested piece in the prior art. After the tested piece is kept for several days before being soaked in water for fostering, the inner mould is detached crosswise, so that the disturbance of the tested piece is reduced and the practical intensity of the tested piece is effectively ensured.

Description

technical field [0001] The invention relates to an inorganic binder unconfined compressive strength sleeve mold device and method. Background technique [0002] Existing mold testing devices for unconfined compressive strength of inorganic binders generally include cylindrical steel testing molds. During operation, put the test mold on the tool pad, and the bottom of the test mold is equipped with a lower pressure pad, then add inorganic binder into the test mold, and put the upper pressure pad into the test mold to make the upper and lower The pressure cushion block compresses the inorganic binder to make it pressure-formed. After the test piece is formed, use the stripper to push the test piece directly, and push the test piece out of the test mold. Since the pressure of the test piece is relatively high when it is formed (the cement is stable and crushed) The compressive stress of the test piece is about 50 MPa), the friction between the inner wall of the test mold and t...
