Abstract
The utility model relates to a measuring device for the initial shrinking rate of a concrete material, which pertains to the performance measuring field of the architecture material; the device comprises a sample mould and a length measuring device, wherein the sample mould is a corrugated pipe provided with straight pipe shaped terminals at both ends, and the terminals are provided with pipe pistons; when in use, the stirred concrete sample is added into the corrugated pipe mould and allowed to stand until the solidification ends of the concrete. Both ends of the mould are sealed with the pistons, thus determining the shrinking rate of the sample according to the change of the length; the utility model has the advantages of simple structure and economic cost, which meets the new requirements of the technology and art development of concrete materials.
Description
Technical field
The utility model relates to a kind of measurement mechanism, and especially a kind of device that is specifically designed to the early-age shrinkage performance measurement of materials such as cement concrete belongs to the building materials technical field of performance test.
Background technology
Understand according to the applicant, the various devices that existing cement concrete material shrinkage factor is measured are basic engineering with GB GB751-81 all.During use, must first sample moulding, again through leaving standstill, operation such as precuring, initial length and later length variations are measured in the demoulding after common 24 hours then.Be that sample must be measured the initial length of sample then earlier through stripping process.
In fact, common cement slurry has been finished through 7～9 hours and has been condensed, and newly mixes flowability complete obiteration before cement slurry condenses end of cement mortar material or fresh concrete material, and the material appearance volume is definite.Therefore, should measure the initial length of sample setting time after the end immediately at cement slurry.But cement slurry has just been finished when condensing, and concrete sample intensity is very low, can not carry out the stripping process operation, and sample must leave standstill maintenance a period of time (being generally 24 hours), and intensity just can reach the requirement of the demoulding.This shows that existing cement concrete material shrinkage factor measurement mechanism can not be measured concrete sample and condense from cement slurry and finish contraction situation to finishing in this section of stripping process period.
Along with the development of cement concrete material technology, complementary Binder Materials addition content increases considerably in the concrete, water cement ratio reduces significantly, causes concrete early-age shrinkage rate, and particularly rate of self-contraction obviously increases.The early-age shrinkage rate of concrete material is fairly obvious to effect of material performance.Therefore need measure accurately concrete material early-age shrinkage rate.
Summary of the invention
The purpose of this utility model is: at the problem that existing measuring technique exists, proposes a kind of can concrete material condense finish after, without stripping process, directly carry out the cement concrete material early-age shrinkage rate measurement mechanism of shrinkage measurement.
In order to reach above purpose, cement concrete material early-age shrinkage rate measurement mechanism of the present utility model comprises sample mould and horizontal metroscope, and it is characterized in that: described sample mould is the corrugated tube that two ends are shaped on the straight tube-like port, and described port is furnished with pipe close.
During use, the setting time of pressing national standard method test water slurry body earlier.The concrete sample that will mix and stir joins in the corrugated tube mould then, two ends seal with pipe close, leaving standstill sample finished up to the setting time of cement slurry, the sample of mould of will ining succession is immediately put into horizontal metroscope and is measured, can measure sample initial length and later length variations, thereby determine the shrinkage factor of sample according to length variations.
Obviously, the utility model is simple in structure, and cost economy after can be implemented in concrete material final set and finishing, is carried out shrinkage immediately and measured, thereby satisfies the new demand of cement concrete material technology development.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment sample mould of the utility model.
Fig. 2 is an embodiment user mode of a utility model synoptic diagram.
Embodiment
Embodiment one
The cement concrete material early-age shrinkage rate measurement mechanism of present embodiment as depicted in figs. 1 and 2, sample mould is a plastic film capicitor 3, two ends are straight tube-like port 2.Two-port 2 is furnished with round table-like pipe close 1 respectively.Horizontal metroscope is referring to Fig. 2, mainly falls the fixed bar 6 that " product " font distributes by the back-up block 8 at two ends and three at middle part and is formed by fixedly connecting, and passes through fastening nail 5 fixedly dial gauge 4 and gauge head 7 on two back-up blocks 8 respectively.Horizontal metroscope is furnished with length standard bar 9.
During use, the concrete sample that mixes and stirs is joined in the plastic ripple pipe mold, two ends seal with pipe close 1, leave standstill sample up to the concrete material end of condensing, the sample of mould of will ining succession is afterwards put on two fixed bars 6 of horizontal metroscope, by par 9, can measure sample initial length and later length variations easily by the dial gauge reading, thereby determine the shrinkage factor of sample.
Facts have proved, the cement concrete material early-age shrinkage rate measurement mechanism cost economy of present embodiment, easy to use, measure accurately, can satisfy after concrete material condenses end, carry out the demand that shrinkage is measured immediately.
