Centrifugal concrete slump testing device

Abstract

The invention discloses a centrifugal concrete slump testing device which comprises a centrifugal suspension slump cylinder, and the centrifugal suspension slump cylinder comprises a fork arm, a bracket, a concrete slump outer cylinder, a concrete slump inner cylinder, a connecting rod mechanism and a concrete slump bottom cylinder; the fork arm is connected with the bracket through a pin shaft I; the bracket is fixedly arranged on the outer wall of the concrete slump outer cylinder through a pin shaft II; a concrete slump bottom cylinder is arranged at the bottom of the concrete slump outer cylinder, and the concrete slump outer cylinder and the concrete slump bottom cylinder are of an integrated structure; a sliding groove is formed in the inner wall of the concrete slump outer cylinder, a sliding rail is arranged on the outer wall of the concrete slump inner cylinder, and the concrete slump outer cylinder and the concrete slump inner cylinder are in sliding fit. The spring bayonet lock is arranged at the connecting rod mechanism, the concrete slump inner cylinder is pre-fixed through the spring bayonet lock, and the viscosity data of the viscous concrete are compared by comparing the overflow amount of the viscous concrete with different components at the same rotating speed.

Description

technical field [0001] The invention relates to a device structure for concrete slump testing, belonging to the technical field of concrete testing, in particular to a centrifugal concrete slump testing device. Background technique [0002] Concrete slump mainly refers to the plasticizing performance and pumpability of concrete. The factors affecting concrete slump mainly include gradation changes, water content, weighing deviation of weighing instruments, and the amount of admixtures, which are easily overlooked. temperature of cement, etc. Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete. [0003] With the development of new material technology, the application of adding new materials to concrete to obtain modified concrete properties is becoming more and more common; Insufficient strength and other problems affect its safety and use function. In pract...

Problems solved by technology

The slump test in the concrete modification test is very important to analyze the modification performance of concrete, but for special concrete, such as concrete samples with good bonding performance, general ductility and elastic deformation, the conventional concrete slump test When the test effect is often poor

[0004] Chinese patent 202122203246.7 discloses high flexural strength polymer modified recycled concrete slump test equipment, which mainly improves the prior art when testing the concrete slump, which is usually caused by manual pulling up of the slump cylinder. The situation that the direction is inclined and scratches the concrete pile, thereby aggravating the collapse of the concrete pile and affecting the measurement results, including the equipment s
