Abstract

The invention belongs to the technical field of building material detection devices, and especially relates to a concrete performance test experiment device. A large amount of dusts can be generated when existing concrete is crushed, but an existing testing device cannot treat dust. The device comprises a pressure sensor and a base, a first groove is formed in the top of the base, a fixed seat isfixedly mounted at the bottom of the first groove, a sliding sleeve is slidably mounted on the fixed seat, a round hole is formed in the sliding sleeve, a round rod is rotationally mounted in the round hole, a fixed block is fixedly mounted at one end of the round rod, and a base plate is fixedly mounted at the top of the fixed block. By arranging the base plate, concrete can be placed on the baseplate and the base plate can be lifted up during testing, so that the tested and broken concrete can be quickly poured out; and a motor drives a pressing column to perform testing, and meanwhile, allstructures in a shell can be driven to be linked, so that dust generated by the broken concrete is sucked into water.

Description

technical field [0001] The invention relates to the technical field of building material testing devices, in particular to an experimental device for testing concrete properties. Background technique [0002] The performance of concrete includes many kinds. The viscosity of uncured concrete is its most important property, while the bearing strength of solidified concrete is its most important property. The bearing strength of concrete after solidification determines the quality of concrete built. The strength of the building, in order to ensure the quality of the concrete, performance testing is required before the concrete is put into use. [0003] In the prior art, when the performance of concrete is usually tested, the concrete is crushed mainly through high pressure, and the performance of the concrete is judged by observing the force required to crush the concrete. A large amount of dust is produced, and the existing test device cannot handle the dust, so a new device ...
