Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mortar production, and specifically relates to a mortar compression testing device. BACKGROUND

[0002] Mortar is a bonding material used in bricklaying, which is made of sand and cementing material (cement, lime, clay, etc.) in a certain proportion and water. It is also known as mortar or mortar. Commonly used mortars include cement mortar, mixed mortar (or cement-lime mortar), lime mortar, and clay mortar. Mortar is used for masonry and component installation of bricks, stones, and blocks. Mortar test blocks are materials made by placing mortar in a mortar test mold after it has been mixed in the right proportions. They are cubic test blocks made to test the strength of the mortar.

[0003] To test the compressive strength of mortar test blocks, such as the anti-compressive strength testing device for mortar production disclosed in publication number (CN220794898U), which includes a portable detection table, a groove in the center of the upper surface of the portable detection table, and a placement box installed in the groove. The upper surface of the portable detection table is fixedly connected with a side bracket on one side. The top of the side bracket is fixedly connected with a top bracket. A pressing mechanism is installed on the inner bottom wall of the top bracket. The size of the placement box is consistent with the size of the groove. A first pressure sensor is fixedly connected to the inner bottom wall of the groove. A detection mechanism is provided on the inner wall of the placement box. A mortar test block is placed inside the placement box, and the mortar test block abuts the detection mechanism.

[0004] The first pressure sensor in the groove of the placement box obtains the pressure value of the test mortar test block. However, there are still technical problems: since it is a compressive strength test, pressure needs to be applied to the top of the mortar test block. Due to the influence of the weight of the mortar test block itself, when the mortar test block deforms, the pressure it receives includes the pressure applied to the mortar test block plus its own weight. The pressure detected by the first pressure sensor includes the pressure of the above two, resulting in inaccurate compressive data of the detected mortar test block. UTILITY MODEL CONTENTS
