Abstract

The invention relates to the field of concrete detection technologies, in particular to a device and a method for precisely detecting concrete slump through multiple parameters. The method is characterized by comprising the detection steps that (1) a scale upright is installed, and a temperature probe is fixed; (2) a slump cone is placed, and a horizontal measuring rod is connected to the scale upright; (3) a leveling bubble is installed, and a thermodetector is connected with the temperature probe; (4) the height of the slump cone is read; (5) concrete is pored and vibrated, and the casting temperature of concrete is recorded; and (6) the slump cone is taken off, a height value is read after slumping is over, and the difference between the readings is the slump. Compared with the prior art, the device and the method have the advantages that (1) the device is simple in structure, convenient to assemble and suitable for a construction site; (2) the casting temperature of the concrete can be measured while the concrete slump is measured, and evaluation on concrete quality is more accurate; and (3) difficulties existing in current concrete construction are solved, and an effective technical means is provided for achieving a concrete building construction goal with higher precision.

Description

technical field [0001] The invention relates to the technical field of concrete detection, in particular to a device and method capable of accurately detecting concrete slump with multiple parameters. Background technique [0002] Slump (Slump) mainly refers to the plasticizing performance and pumpability of concrete. It is a quantitative index to measure its degree (plasticization and pumpability) and is used to judge whether the construction can proceed normally. Concrete slump is mainly affected by changes in gradation, water content, weighing deviation of the horizontal device, the amount of admixtures, and the temperature of cement that is easily overlooked. Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, and is a comprehensive index that can reflect the water retention, fluidity and cohesion of concrete. [0003] The slump is mainly carried out at the construction site. It is an important factor to judge whether...
