The problem that the reference water consumption is difficult to accurately judge in the existing concrete test process is solved. Belongs to the field of concrete test research.
Description
Technical Field
The invention relates to a method for measuring the reference water consumption of a concrete test, belonging to the field of concrete test research.
Background
At present, in the process of a mix proportion design test of a concrete mixing plant, raw materials can be mixed into a cake shape after being mixed by adding water into the raw materials through visual inspection by means of empirical data and visual inspection when the water consumption is designed as a reference, the surface is glossy, but the visual inspection method has high requirements on experience and poor accuracy, the problems of inaccurate water consumption judgment and the like are easily caused, and the concrete performance is greatly influenced by inaccurate water consumption judgment.
Disclosure of Invention
The invention provides a method for measuring the reference water consumption of a concrete test, which aims to solve the problem that the reference water consumption is difficult to accurately judge in the existing concrete test process, and the reference water consumption is inaccurate to judge, thereby having great influence on the working performance, the strength and the long-term performance of the concrete.
In order to solve the problems, the method for measuring the water consumption of the concrete test standard is supposed to be adopted, and comprises the following steps:
the method comprises the following steps: mixing concrete, pouring aggregate, powder, water and other raw materials except additives into a mixer, mixing for 6 minutes, covering a mixer cover after mixing is finished, placing the mixture in the mixer, standing for 10 minutes, and pouring the mixture onto an iron plate;
step two: preparing a tool, namely wetting the surfaces of the slump cone and the bottom plate while mixing the concrete;
step three: loading the concrete mixture into a slump cone in two layers, wherein each layer is inserted and poured from the edge to the center for 25 times, the first layer is loaded to a half position of the cone, the second layer is full, and the cone mouth is leveled after the insertion and pouring are completed;
step four: measuring, namely after removing concrete on the cylinder edge, stably lifting the slump cylinder along the vertical direction and slightly placing the slump cylinder beside the slump cylinder, and measuring the distance from the highest point of the sample to the cylinder top by using a steel ruler after the sample does not slump for 30 seconds any more;
step five: judging that the water consumption is a reasonable reference when the distance is more than 5mm and less than or equal to 10 mm; when the distance is more than 10mm, the reference water consumption is excessive; when the sample does not undergo slump deformation, the amount of water used is insufficient.
Compared with the prior art, the slump constant determination method has the advantages that the slump value is adopted to determine the water consumption, the specific numerical value is used as a determination basis, the influence of human factors of the original water consumption visual measurement method is reduced, the test result is more accurate, the test amount of a visual measurement method is reduced, the method is more convenient and efficient, and the operation of concrete preparation personnel is facilitated.
