Quality signals, pressure signals and temperature signals are displayed on the main interface of system detecting software through the wireless temperature and pressure transmission module and the wireless quality transmission module, so that the water-gel ratio, the respective water consumption, the air content, the volume weight and the temperature of concrete mixture can be detected through the multiple arithmetic by the system detecting software on the basis of inputting related parameters concerning the concrete mixture ratio. The utility model can accurately, rapidly and conveniently detect the five indexes of the concrete mixture in twenty minutes and is suitable for concrete construction quality control on the spot.
Description
Technical field
The utility model relates to concrete mix combination property field quick detection instrument, be mainly used in the fast measuring of concrete mixture characteristic water-cement ratio, folk prescription water consumption, air content, unit weight and mixture temperature, be specially adapted to concrete on construction site mixture performance detection.
Background technology
Concrete material is as one of most important construction material in the world today, and the quality of concrete quality both had been related to the operation safety of cement concrete constructions thing, has influence on the expense of works later maintenance again.Mostly concrete durability is at the concrete hardening body to have hysteresis quality, limitation and be difficult to reparation property.If with the concrete mix is research object, be target with control concrete mix integrated performance index, concrete quality is controlled, can overcome the hysteresis quality and the limitation of existing concrete permanance detection means.Yet also do not have to detect fast, accurately and simultaneously now the instrument and equipment of a plurality of performance index of concrete mix, in addition one suitable, can measure accurately that concrete important parameter the most---the instrument of water-cement ratio does not have yet.
Water is the concrete key component of preparation, and water plays very important effect to the formation of xoncrete structure, also is the carrier and the necessary condition of destroying concrete structure simultaneously.Therefore; accurately measure actual used water amount in the concrete; to guaranteeing that concrete permanance has important role, but because the deficiency of detection means, detection method and the evaluation index to concrete on construction site water-cement ratio and folk prescription water consumption also do not have corresponding pressure standard at present.
Britain has researched and developed FCT101 type fresh concrete tester, is used for the detection of the on-the-spot quality of fresh concrete.This method is to refuse to calculate the water cement ratio of concrete mix by turning round of concrete mix, but this measuring technology is still in conceptual phase, and it records data need carry out comprehensive comparative analysis with actual actual value, has influenced the popularization of this assay method.The domestic people of having proposes with material analysis method and pairing comparision concrete mix to be carried out the technology of real-time oversight, the material analysis method is to adopt the method for drying-weighing to calculate concrete mixture ratio, need calculate saturated aqueous rate, silt content and the influence coefficient of coarse-fine aggregate, this method is to carry out part in existing Standard for test methods of properties of ordinary concrete mixture standard to improve, but still need to sieve and dry, human factor is big, and influence factor is many, and its precision can't be guaranteed.The assay method that also has a kind of water-cement ratio is to calculate concrete water-cement ratio according to Archimedes principle, and this method will be set up the rule between water-cement ratio and the sand glue ratio on the basis of a large amount of laboratory tests, just can be used to detect water-binder ratio.
At present, also do not have fast, accurately to detect concrete mix combination property rapid detection apparatus, especially be applicable to the working-yard environment, can detect a plurality of performance index of the concrete mix instrument of (mainly comprising water-cement ratio, folk prescription water consumption, air content, unit weight and mixture temperature) simultaneously.
Summary of the invention
Patent of the present invention has overcome the existing concrete water-cement ratio and folk prescription water consumption checkout equipment measuring accuracy is low, human factor big and can't be applicable to the on-the-spot shortcoming that detects, develop one and contained the concrete mix field quick detection instrument that three kinds of sensors (pressure, quality and temperature), wireless transmit receiver module and system detect software and container, in 20 minutes, can determine water-binder ratio, folk prescription water consumption, air content, unit weight and five performance index of mixture temperature.
The technical solution of the utility model, as illustrated in fig. 1 and 2, temperature sensor 7 and temperature and pressure wireless transport module 8 are contained in the gland bonnet 6 that pressure transducer is housed, gland bonnet 6 can be fixed on the right cylinder light aluminum alloy container 9, and circular measuring apparatus 10 links together with quality wireless transport module 11.During detection, the container that is stamped gland bonnet is placed on the measuring apparatus.
The utility model is to mention the original pressure of front and back and the quality before and after equalized pressure and the water-filling according to equalizing valve, measure concrete unit weight and air content, in conjunction with the concrete mix correlation parameter, calculate the water-cement ratio and the folk prescription water consumption of concrete mix, the mixture temperature is by temperature sensor measurement.
The utlity model has wireless transmission function, quality signal, pressure signal and temperature signal are realized by wireless transport module, the occurrence of signal shows in the main interface of system's detection software, behind to be tested the finishing, system detects software can provide the index that will measure concrete mixture characteristic automatically.
The utlity model has that concrete 's air-containing calculates automatically, numeral shows and calibrating function, eliminated traditional air content instrument by personal error that total indicator reading produced, this system in use for some time, or when data that this equipment is surveyed are produced query, can demarcate the air content instrument, by the accurate mensuration of change air content instrument correction factor realization air content.

Fig. 1 is gland bonnet and container johning knot composition, and Fig. 2 is the measuring apparatus that the mass transport module is housed.1. vent valves among the figure, 2. gas admittance valve, 3. equalizing valve, 4. water filling port, 5. water delivering orifice 6. is equipped with the gland bonnet of pressure transducer, 7. temperature sensor, 8. temperature and pressure wireless transport module, 9. container, 10. measuring apparatus, 11. quality wireless transport modules.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: operation steps of the present utility model, concrete mix is packed in the container 9 of known volume, and make concrete be full of container, gland bonnet 6 that pressure transducer is housed with seal of vessel, is accurately taken by weighing its quality with measuring apparatus 10; From water filling port 4 water-filling to container 9, there is water to discharge up to water delivering orifice 5, accurately take by weighing the quality behind the water-filling again; After treating that quality signal is stable, inject air from gas admittance valve 2, regulate micrometering valve 1, make pressure stability at 100kPa, open equalizing valve 3, gas is entered be equipped with in the concrete container 9, during the equal pressure balance, automatically read concrete force value, measure the concrete mix temperature according to temperature sensor 7; Detect software by concrete mix combination property system and measure concrete folk prescription water consumption, water-cement ratio, air content, unit weight and mixture temperature.
