See the experimental rig of a kind of quantitative assessment pitch shown in Fig. 1 to Fig. 4 and coarse aggregate adhesiveness, including thermostatted water
Case 5, is provided with heating pipe 9, is additionally provided with temperature sensor 10, described constant temperature in described constant temperature water tank 5 in described constant temperature water tank 5
Water tank 5 outer wall is provided with temperature controller 11, and described temperature sensor 10 is connected with described temperature controller 11, described temperature
Controller 11 is connected with described heating pipe 9, described constant temperature water tank 5 is additionally provided with electric machine support 2, on described electric machine support 2
It is provided with power part 3, the rotary shaft 8 of described power part 3 is connected with netted experimental provision, described netted experimental provision position
Internal in constant temperature water tank 5 and do not have any contact with constant temperature water tank 5, described netted experimental provision includes test bracket, appearance of gathering materials
Device 7, described dump vessel 7 is fixed on test bracket.
Further, described constant temperature water tank 5 is arranged on base 1.
The utility model process when in use is as follows, 1., weighs quality in 25 DEG C of tanks for the netted experimental provision
M0.By the ready loading dump vessel 7 that gathers materials, put in 25 DEG C of water tanks, then it is common with gather materials to weigh netted experimental provision
Mass M1。
2. opening heating pipe 9, setting constant temperature water tank 5 temperature as 80 DEG C, concrete is detected wherein by temperature sensor 10
Temperature, and control water temperature by temperature controller 11.
