Abstract
The utility model relates to a device for measuring concrete shrinkage, which is characterized in that the device is composed of a container bottle, a bottle cap, a rubber plug, a glass tube and a sample bag, wherein, the sample bag filled up with concrete is arranged in the container bottle on which the bottle cap is covered, and the glass tube is vertically inserted in the upper opening of the bottle cap via the rubber plug. The container bottle is sealed with the bottle cap, a bottle cap mouth, the rubber plug and the glass tube; the container bottle, the bottle cap and the glass tube are all filled up with water. The utility model has the advantages of simple operation and high measuring precision reaching microstrain namely 1*10<-6 >, and can be used for measuring deformation of concrete pouring from zero-time, namely shrinkage in the next day of pouring, measuring volume shrinkage of cement, cement mortar and concrete, and measuring volume expansivity of some cement, mortar and concrete. Variance of the liquid level of the glass tube is convenient to match with computer continuous monitoring.
Description
Affiliated technical field
The utility model relates to the building materials testing tool, promptly a kind of device of measuring the concrete shrinkage rate.
Background technology
It is that foursquare rectangular examination is fast that the concrete shrinkage factor of present domestic detection is all used xsect, on comparator, measure the method for variation of the length of test block with clock gauge, the test block cast is after 24 hours, it is just long to measure test block, then at 2d, 3d, 5d, 7d, 14d, 28d...... equal time is measured the variation of test block length, reduction according to test block length calculates shrinkage factor, this way has been made the countries concerned's standard, troublesome poeration, and out of true in the actual measurement, can not measure the shrinkage factor of concrete in one length of time, therefore in engineering practice, seldom use.
Summary of the invention
The utility model places the water of container to concrete sample, by observing the decline of container middle water level, measures the shrinkage factor of volume of sample, and the utility model provides such covering device.
The device of this mensuration concrete shrinkage rate, form by container bottle, bottle cap, rubber stopper, glass tube and sample bag, fill concrete sample bag and place container bottle, bottle cap covers on container bottle, glass tube is by vertical being inserted in bottle cap suitable for reading of rubber stopper, container bottle and bottle cap all seal between bottle cap mouth, rubber stopper and the glass tube, have all filled water in container bottle, bottle cap, glass tube.
Advantage of the present utility model: 1, simple to operate, 2, the measuring accuracy height, can reach microstrain, promptly 1 * 10
-63, the distortion that rises in the time of can measuring concrete depositing zero can be measured the shrinkage factor in the cast one day after.4, the variation of glass tube liquid level is convenient to the computing machine continuous monitoring supporting.5, cement, sand-cement slurry, concrete volumetric shrinkage be can measure, some cement, mortar, concrete cubical expansivity also can be measured.
Description of drawings
Fig. 1 is a sectional view of the present utility model.Among the figure 1, container bottle, 2, bottle cap, 3, glass tube, 4 rubber stoppers, 5, sample bag, 6, concrete, 7, water, 8, proofread and correct glass tube.
Embodiment
In device shown in Figure 1, operation as follows: the 1. surface of contact of cleaning container bottle 1 and bottle cap 2, rubber stopper 4 is inserted in the end of glass tube 3, then the two is inserted the suitable for reading of bottle cap 2, the blended rubber sealing; 2. sample bag 5 is rubber bulbs, measure its volume; 3. water, cement, sand, cobble are weighed, mix system concrete 6, with concrete 6 sample bag 5 of packing into, tamping, the sealing-plug of screwing on is measured the cumulative volume of sample bag; 4. sample bag 5 container bottle 1 of packing into, cover bottle cap 2, gluing sealing between container bottle 1 and container cover 2; 5. pass through glass tube 3 topped up with water in container bottle 1, bottle cap 2, glass tube 3 after 30 minutes; 6. this device is placed constant temperature enclosure, the liquid level of manual record or installation computer monitor equipment records glass tube 3, record 1h, 2h......24h, the liquid level of 1d, 2d......180d, calculate the volume that sample bag 5 shrinks in view of the above, the volume ÷ (volume of the packed concrete cumulative volume-sample bag of sample itself) that then concrete volumetric shrinkage=sample bag shrinks.
Sample bag is getting in touch of closed concrete and external environment preferably, rubber bulb can be ignored to concrete parcel power, therefore the concrete shrinkage rate of measuring with this method can reflect the three-dimensional shrinkage rate of this material more really, and in traditional method, only can reflect the shrinkage factor on the length direction.Because evaporation of water in the glass tube 3, liquid level is descended because of water evaporates, can install one of the vertical placement in next door and the identical correction glass tube 8 of glass tube 3 internal diameters of glass tube 3 at this, opening suitable for reading, the end opening sealing, go out to load onto the water of same height in this pipe, its drop-out value can be used as the corrected value of drop-out value that the utility model is surveyed, and is deducted during calculating.
Claims (2)
1, a kind of device of measuring the concrete shrinkage rate, it is characterized in that it is made up of container bottle, bottle cap, rubber stopper, glass tube and sample bag, fill concrete sample bag and place container bottle, bottle cap covers on container bottle, glass tube is inserted in bottle cap suitable for reading vertically by rubber stopper, container bottle and bottle cap all seal between bottle cap mouth, rubber stopper and the glass tube, have all filled water in container bottle, bottle cap, glass tube.
2, according to the described a kind of device of measuring the concrete shrinkage rate of claim, it is characterized in that: on the next door of glass tube, vertically place an identical correction glass tube of internal diameter with it, opening suitable for reading, end opening seals, and loads onto the water of same height in this pipe.
