Tester for cement hydration heat device general is at present as application number tester for cement hydration heat disclosed in the Chinese patent of 200820037954.X, be included on constant temperature calorimetric case and be fixedly installed hollow bearing, bearing is provided with motor pressing cover, motor pressing cover is fixedly installed motor, bearing is rotatably connected to stirring rod, and stirring rod bottom extend in constant temperature calorimetric case; And for example application number a kind of hydrated cementitious heat test heat measurement equipment disclosed in the Chinese patent of 201420515495.7, comprises water bath, self prime pump, data acquisition controller, electrically heated rod and shell, in sample plasma bottle, is inserted with temperature sensor.
Adopt above-mentioned existing determining instrument, test period is long, be unfavorable for the large formula ratio of testing laboratory, go out the demand of result fast, and hydration heat and actual temperature simply can not be equivalent to; The workload adopting the words of mass concrete then to test is large, waste material.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned prior art Problems existing, provide a kind of easy to operate, measure sand-cement slurry hydration heat warm raising measurement set fast.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of sand-cement slurry hydration heat warm raising measurement set, comprise temperature sensor, it is characterized in that: also comprise incubation chamber and thermometric line, the lid that described incubation chamber comprises box body, removably connects with described box body, the cup for splendid attire sand-cement slurry is provided with in described incubation chamber, one end of described thermometric line is connected with described temperature sensor, and the other end is inserted in the sand-cement slurry in described cup through described lid.
For ease of thermometric line through lid, described lid offers the hole passed for described thermometric line, described hole is by polyurethane seal, and polyurethane has the effect of insulation, can seal, again can to incubation chamber inside holding.
For ease of taking out after sand-cement slurry sclerosis, described cup is made up of the plastics of hard, and the external diameter of described cup is less than the internal diameter of described box body.
Carry out for ease of multiple sample measurement simultaneously, described temperature sensor has multiple port, each port connects a described thermometric line.
Described box body and lid are threaded, and the junction of described box body and lid is provided with urethane sealant layer, thus make the junction of the box body of incubation chamber and lid can realize sealing, can realize again insulation.
Compared with prior art, the utility model has the advantage of: by arranging incubation chamber, can avoid because the many temperature rise curves of small volume of water cement mortar heat loss are not obvious, make experimental data otherness large, be beneficial to the analysis of test figure; Directly measure sand-cement slurry hydration heat temperature, the test duration is short, and data conclusion has directive significance to concrete test; Apparatus structure is simple, easy to operate, few to manpower, Raw Material Demand, is well suited for the demand that laboratory test formula is many, result goes out fast.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of warm raising measurement set of the present utility model;
Fig. 2 is the cut-open view of incubation chamber first embodiment of warm raising measurement set of the present utility model;
Fig. 3 is the cut-open view of incubation chamber second embodiment of warm raising measurement set of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
Embodiment one
See Fig. 1 and Fig. 2, a kind of sand-cement slurry hydration heat warm raising measurement set, comprises temperature sensor 1 and incubation chamber 2, and incubation chamber 2 comprises box body 21 and lid 22, and box body 21 and lid 22 removably connect, thus is convenient to both separation.
The lid 22 of incubation chamber 2 offers porose 23, and one end of thermometric line 4 is connected with temperature sensor 1, and the other end enters in box body 21 through hole 23.Temperature sensor 1 is provided with multiple port, and each port connects a thermometric line 4, and the quantity of incubation chamber 2 is corresponding with thermometric line 4, so that multiple sample measurement carries out simultaneously.During test, after thermometric line 4 penetrates, the polyurethane 24 with heat-insulating property is utilized to be sealed in hole 23.
Be provided with cup 3 in incubation chamber 2, for splendid attire sand-cement slurry 5, cup 3 is preferably made up of the plastics of hard.The external diameter of cup 3 is less than the internal diameter of the box body 21 of incubation chamber 2, and preferably, the external diameter of cup 3 is slightly less than the internal diameter of the box body 21 of incubation chamber 2, can guarantee the amount of sand-cement slurry 5, is difficult to take out after preventing again sand-cement slurry 5 from hardening.
During use, first open temperature sensor 1 and make it be in normal temperature acquisition state, to mix cement mortar 5 contain jolt ramming in cup 3 according to experimental technique, put into incubation chamber 2, lid 22 is tightened sealing; Then thermometric line 4 is entered in box body 21 through the hole 23 on lid 22, and sand-cement slurry 5 certain depth be inserted in cup 3, then use polyurethane 24 seal bore 23, see Fig. 2, note thermometric line 4 degree of depth be inserted in sand-cement slurry 5 is a, and the degree of depth of sand-cement slurry 5 is b, preferably, a=0.5b; Record temperature sensor 1 gathers initial time and the temperature of sand-cement slurry 5 temperature, at the end of waiting until the length of time, copies and gets thermographic data, arrangement, and is taken out in incubation chamber 2 by cup 3, removes the cement block of sclerosis.
