Description
Technical Field
The utility model belongs to the technical field of the concrete detection equipment, especially, relate to a concrete slump check out test set for construction.
Background
The slump of concrete mainly refers to the plasticizing performance and pumpability of concrete, and factors influencing the slump of concrete mainly include grading change, water content, weighing deviation of a weighing apparatus, the dosage of additives, cement temperature and the like which are easy to neglect. Slump refers to the workability of concrete, and particularly to the normal operation of construction, wherein the workability includes the water retention, the fluidity and the cohesiveness of the concrete. The workability of concrete refers to whether the concrete is easy to construct and operate and uniform and compact, and is a very comprehensive performance including fluidity, cohesiveness and water retention. The influence on the workability mainly comprises the water consumption, the water-cement ratio, the sand rate, the cement variety, the aggregate condition, the time, the temperature, the additive and the like.
The slump of concrete is determined according to the conditions of the structural section, the content of reinforcing steel bars, the transportation distance, the pouring method, the transportation mode, the vibrating capability, the climate and the like of a building, and the slump is comprehensively considered when selecting the mixing proportion and is preferably smaller.
At present, no measuring method capable of comprehensively reflecting the workability of concrete mixtures exists, slump tests are usually carried out in construction sites and laboratories to measure the fluidity of the mixtures, and visual experience is used for evaluating the cohesiveness and the water retention. Specifically, the slump test method is as follows: the concrete mixture is filled into a standard cone slump cylinder according to a specified method, after the cylinder is filled and scraped, the cylinder is lifted vertically upwards and moved aside. Concrete mixes will slump due to their own weight. Then, the size of the slump downward was measured, and this size (mm) was taken as the slump, and as an index of fluidity, the larger the slump, the better the fluidity. When the slump is more than 220mm, the slump cannot accurately reflect the fluidity of the concrete, and the average diameter of the concrete after being expanded, namely the slump expansion degree, is used as a fluidity index. While slump tests are carried out, the cohesiveness and the water-retaining property of the concrete mixture should be observed so as to comprehensively evaluate the workability of the concrete mixture.
In the prior art, the slump detection process is mainly completed manually, namely, concrete is filled into a standard conical cylinder in a manual mode, and the conical cylinder is lifted upwards manually after being filled and strickled off. The method is labor-consuming in operation, and on the other hand, the cone barrel cannot be lifted upwards vertically in the manual lifting process, but always inclines and disturbs to a certain degree, so that the slump measurement is inaccurate. Therefore, it is necessary to develop and design an auxiliary inspection apparatus capable of performing the above-described standard inspection process.
