Description

A kind of device measuring the concrete batching system slump and divergence

Technical field

The utility model relates to the devices of a kind of measurement concrete batching system slump and divergence.

Background technique

The weight of quality control when the concrete batching system slump and divergence test are concrete mix proportion experiment and construction Reference index is wanted, is the parameter often detected in concrete works.The slump is that concrete batching system collapses under self gravity Height, divergence is the diameter that concrete batching system extends after slump.Concrete batching system is before concrete is unhardened Intermediate products are tested by concrete batching system performance detection, and test data can be used as concrete mix adjustment foundation, also It can be used as concrete construction property guidelines foundation.The slump and divergence two indices are that concrete batching system is most common, The special slump is the index that all concrete batching systems must measure, and divergence is that high lift pump send concrete, underwater coagulation The concrete batching systems such as soil, self-compacting concrete must survey index, and measuring capital equipment used in two parameters is equally to set It is standby, so the accurate and operability of equipment detection is crucial.The current measurement concrete batching system slump on the market is set Standby mainly common slump cone, structure is simple, is made of a truncated cone-shaped iron sheet, cylinder cap and tamper, and equipment self-weight is light, operation Simply, but test result difference is big；Height is required for test operator, testing crew will plug and pound on one side in operating process, Foot pedal again, slump cone are easy disturbance, and generation situations such as have spillage, influence test result；Due to the slump Cylinder be generally made of the iron sheet of one layer of 1mm thickness, be easily deformed, concrete batching system charge weight is inconsistent, cause collapse highly with True value has differences；Having a step during test is that will promote the slump in 3~7s of slump cone to complete, this mistake It varies with each individual in journey, when promotion can not balance rising and be easy to encounter concrete batching system, cause concrete batching system to collapse high Degree is inaccurate, collapses on one side or generation situations such as failure by shear, influences testing result.The concrete batching system slump and divergence examination The process of testing must be carried out from two testing crews with progress, people's primary operational, another person carry out concrete batching system Charging and auxiliary, it is indispensable, otherwise it is unable to complete test.Such a extremely simple test is not enough closed because of the equipment used It manages and two people must be expended simultaneously and tested, waste of manpower cost.
