By adopting the specific forming device, a circular test piece different from a conventional test piece is formed, the defect that the surface and the internal condition of the conventional cubic and cylindrical test piece are difficult to observe is overcome, the comprehensive evaluation on the compatibility of the cementing material and the additive can be realized, and the technical blank of the existing detection standard is filled.
Description
Technical field
The present invention relates to a kind of building materials compatibility detection technique and specimen molding device.
Background technology
In building operation, the compound use of Binder Materials and additive is increasing. and along with the increase in the concrete component number, the consistency problem between the various starting material of concrete also shows especially out.Yet, still there is not unified content in the existing building materials method of testing about the comprehensive evaluation material compatibility, cause in work progress, the evaluation subjectivity of material compatibility is bigger.Simultaneously; Cube or right cylinder test block that existing test method adopts usually; It is very suitable that cube or right cylinder test block are used for estimating the test specimen mechanical property; But for the comprehensive evaluation cracking resistance, because main surface crack and the development condition thereof of observing, the test cube and the solid right cylinder test specimen that have corner angle all are not best sample types.Therefore, the relevant scientific and technical personnel of building materials test are necessary to seek a kind of test method and desirable sample type that can objective, easy comprehensive evaluation compatibility.
Summary of the invention
The purpose of this invention is to provide a kind of Binder Materials and the additive compatibility annulus method of inspection and shaped device, solve the technical matters of the method for no material compatibility in the existing building material tests related specifications; And the problem of solution test material compatibility shaping test piece.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of Binder Materials and the additive compatibility annulus method of inspection, step is following:
Said step 1, the time of stirring is at least 3min.
Said step 2; Before the shaped device of packing into; Between base (2) and side form (4), side form (4) splicing seams place seals, and with scraper the slurry layering is blown into the headspace between side form (4) and the core (3); And the air of carrying secretly in the eliminating slurry, simultaneously with slurry upper surface and core (3) and the strickling of side form (4) upper surface.
The method of the air of carrying secretly in the said eliminating slurry is jumped 30 times on the jumping table or direct labor's vibration for the shaped device that will install slurry is placed on.
In the said step 4, the content of consistency check is: it is no abnormal to check that (A) condensing of test specimen has; (B), check the hardness or the intensity of test specimen at the side form of the time of expection form removal dismounting test specimen; (C) whether the surface of inspection test specimen crack performance occurs, and the material stability is made a determination; (D) observe the lateral dehiscence situation of test specimen with reading microscope, the responding ability that the contraction rate of test specimen or microdilatancy performance and tension are crept makes a determination.
The shaped device of described test Binder Materials and additive compatibility; It is characterized in that: comprise base (2), side form (4), core (3) and top cover (1); Said base (2) end face has the bulge loop concentric with it (2.1), and there is the ribs (2.2) of radial distribution its bottom surface, and said side form (4) is stuck in bulge loop (2.1) outside; Said core (3) is stuck in the bulge loop inboard; Said side form (4) and height such as core (3) grade, said top cover (1) is buckled in side form (4) and core (3) end face, and said base (2), core (3) and top cover (1) are fixed as one through the bolt A (5) that runs through above-mentioned three.
Said side form (4) is combined into the domain by two semi-rings, all has pick up the ears (4.1) of evagination on each semi-ring side, and relative two pick up the ears (4.1) are fixedly connected through bolt B (4.2).
The internal diameter of said bulge loop (2.1) is 90mm, and external diameter is 140mm, highly is 5mm.
Said core (3) is cylindrical, and its end face has the interior scrobicular ring (3.1) concentric with it, and its internal diameter is 25mm, and external diameter is 55mm, highly is 10mm.
Compared with prior art the present invention has following characteristics and beneficial effect:
Having filled up present building materials does not have the method for the comprehensive compatibility of unified objective evaluation; Through adopting this method, before construction, carry out the test of multiple proportioning to intending mix, seek out best compatibility; Carry out extensive mix in this ratio then; Effectively avoided in the work progress, caused the construction quality defective because material is incompatible, even do over again.In addition, the shaped device that method of testing according to the invention adopted, volume is little, and convenient in carrying is more suitable for using at the construction field (site).
Adopt special specimen molding device, form the test component of ring-type, overcome traditional right cylinder or cube specimen and had the position, corner, can not reflect the material for test compatibility strictly according to the facts, the inner material compatibility of test specimen can't intuitively be observed.
In addition, annular side form is assembled into the domain through two semi-rings, is convenient in demoulding, and has avoided in knockout course, defective being caused on the test specimen surface, the very big accuracy that has guaranteed test structure.
Also have, ribs is set, increase the stability of installing in the process of the test, and make test unit be convenient to move through base end face at test unit.
The present invention can be widely used in the test and the comprehensive evaluation of Binder Materials and additive compatibility.
