Abstract

The invention discloses a virtual detector for concrete performance and a detecting method and belongs to the field of concrete detection. The virtual detector is composed of a photographing unit, a data input unit, a calculating unit and a result output unit. By pre-arranging a concrete performance prediction model, an original image, obtained in the photographing unit, of a to-be-detected concrete test block and match ratio data are substituted into the concrete performance prediction model, thus corresponding concrete performance prediction values comprising a destruction image, concrete compressive strength and the slump after a concrete compressive strength experiment can be obtained so as to obtain concrete strength and flowability indexes. The problem that concrete strength and slump detection needs tedious, time-consuming and force-consuming manual experiments is solved, the whole detection process is simple and easy to implement, and the structure is concise and is miniaturized. Through the virtual detector and the detecting method, concrete is virtually detected, the cost can be effectively lowered, and environment friendliness is achieved.

Description

technical field [0001] The invention belongs to the field of concrete detection, and more specifically relates to a virtual detector and a detection method for the performance of 3D printed concrete. Background technique [0002] Concrete is the most widely used and economical building material in modern times. It has become a kind of construction engineering material used in modern society, and has made irreplaceable contributions to the development and progress of human society. However, with the continuous acceleration of engineering construction, the defects of high energy consumption and high pollution in the production and application of concrete have gradually emerged, which seriously hinder the development of concrete. In order to meet the development needs of the green manufacturing industry, concrete needs to be continuously injected with fresh blood. [0003] The compressive strength and fluidity of concrete are important indicators to measure the quality of conc...
