Structure durability is particularly significant.Contraction fissure caused by concrete shrinkage accounts for the 80% of total crack, to reduce the crack of concrete, first
First to control the contraction distortion of concrete.Therefore, the research to cement paste contraction distortion is very urgent.
At present, the method for test cement paste contraction distortion both at home and abroad includes eyes with non-contact method and the class of contact method two.Noncontact
The method mainly pre-buried sensor before slurry is poured, determines that test specimen volume (length) changes by the change of other signals, energy
Its shrinkage value of Accurate Determining when slurry early stage there is no intensity, measurement accuracy is higher.But when using this device, one
Embedding two sensors are usually required inside test specimen, hundreds of thousands is first easily for test battery equipment, and cost is prohibitively expensive.Contact method is
Gauge head is pasted after pre-buried or shaping when cement paste is molded, the distance change between the gauge head of two ends is measured by horizontal metroscope,
So as to react the change in size of test specimen.This method is easy to operate, but can not ensure to survey when early stage, slurry there is no sufficient intensity
Head deformation synchronous with early stage slurry, so such a method testing result has larger discrepancy with actual value.Now urgently develop one
Planting both can accurately test the deformation of cement paste early-age shrinkage, and cheap shrinkage test device.
With reference to the actual conditions of job site, a kind of brief test device is have studied, cement paste can be measured and poured certainly
Terminate total contraction to 3d and drying for 3d to 28d is shunk.The data stabilization of the device to test, can be realized complete close in 3d
Envelope, and the floor space very little per complete equipment, cost are less than 500 yuan, compensate for the deficiency of existing setting out method.
The content of the invention
The purpose of this utility model is that current method of testing cost is high or test result is differed with actual value in order to solve
Larger the problem of, so as to propose a kind of easy cement paste shrinkage test device, under the premise of lower cost, can accurately it survey
Obtain the contraction of cement paste overall process from after the completion of pouring.
To achieve these goals, technical solution adopted in the utility model is：
A kind of to test the easy device that cement paste shrinks overall process, described device includes iron stand, base, steel pipe, set
Hoop, steel disc and measuring instrumentss；The bottom center of the iron stand is fixed with base, and base is used to fix steel pipe；The steel pipe is
One section diametrically wire cutting be two halves steel pipe, after the two ends of steel pipe are entangled with cuff, wherein the base is inserted in one end；By water
Cement paste is poured into steel pipe, slurry surface is poured into sealer after it is cooled down, then place the steel disc of circle；The measurement
Instrument is adjustable to be fixed on iron stand, for measuring cement paste amount of contraction.
It is preferred that, the measuring instrumentss are dial gauge, and the measurement end of dial gauge is contacted with steel disc.
It is preferred that, encapsulation process is carried out at the cutting gap of steel pipe and at the gap of steel pipe and base.
It is preferred that, sealer is the fused mass of butter and paraffin.
It is preferred that, base diameter is 40mm-70mm, and diameter of steel tube matches with base diameter.
It is preferred that, steel disc diameter is less than pipe diameter 0.2mm-0.5mm.
The beneficial effects of the utility model are：It can be achieved to pour the total contraction for being accomplished to 3d and 3d to 28d from cement paste
The measurement shunk is dried, test process is closer to engineering practice, and test data is stable.It is less than 500 per complete equipment cost
Member.
