Testing device for concrete slump detection

Abstract

The invention provides a testing device for concrete slump detection, and relates to the technical field of concrete testing. A movable propelling device is fixedly connected to the mounting supporting part; the mobile propelling device is connected with a testing device in a sliding manner; a floating driving part is connected to the movable propelling device in a sliding manner; the floating driving part is connected with a bearing device in a sliding manner; the bearing device is rotationally connected with a cleaning part; a linkage driving part is connected to the bearing device in a sliding manner; an expanding and compacting device is mounted on the inner side of the cleaning part; two treading limiting driving parts are connected to the movable propelling device in a sliding manner; the cylinder wall can be automatically cleaned, the overall compaction uniformity is better, and the operation is more convenient and efficient; the problems that an existing testing device for concrete slump detection cannot be used and is not labor-saving and convenient enough, sample detection is not accurate enough, and meanwhile expansion and comprehensive compaction cannot be achieved are solved.

Description

technical field [0001] The invention relates to the technical field of concrete testing, in particular to a testing device for concrete slump detection. Background technique [0002] Concrete refers to a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The term concrete usually refers to cement concrete as cementitious material, sand and stone as aggregate; it is mixed with water (which may contain admixtures and admixtures) in a certain proportion, and the cement concrete obtained by stirring is also called ordinary concrete. Concrete, which is widely used in civil engineering, because the application of concrete is extremely wide, and the fluidity of concrete can be controlled, so a good test device for concrete slump detection is particularly important at this time. [0003] However, as far as the current testing device for concrete slump detection is concerned, the use is not standardized enough, a...

Problems solved by technology

[0003] However, as far as the current testing devices for concrete slump testing are concerned, they are not standardized enough to easily cause secondary damage to the slumped samples. As a result, the sample detection is not accurate enough, and at the same time, the expansion and comprehensive compaction cannot be achieved, resulting in unrealistic concrete uniformity in the bucket, and poor defoaming effect, affecting test accuracy, poor sealing effect, poor overall installation adaptability, and inability to realize diversified testing , the data is not comprehensive enough
