The drying device that object is dried and the meausring apparatus that the quality for the filler to outflow measures.The dry dress
Set concretely sopping rag or fan etc..For example, after filler flows out and is collected, air-flow can be generated by fan
The vapor on filler surface is taken away, the evaporation of residual moisture in filler is accelerated.Later, by meausring apparatus, such as balance, electricity
Son claims etc., is measured to the quality of the filler after drying, is calculated according to the mass density relationship of filler and to be collected into
The volume of filler, you can obtain the total volume of crack area.
Based on the system of above-mentioned measurement cement base test specimen cracking degree, referring to Fig. 3, the utility model also provides a kind of survey
The method for measuring cement base test specimen cracking degree comprising following steps：
S100, filling concrete base test specimen：Cement base test specimen with several crack areas is placed in the filler of liquid
In, make the inside of several crack areas of the filler full of cement base test specimen of liquid；
S200, filler to be measured is obtained：The filler of cooling liquid state simultaneously makes its solidification, cement base test specimen is taken out, to cement
Base test specimen heats so that the filler of the inside of several crack areas is melted out；
S300, crack area volume is acquired：It collects the filler of outflow and weighs its quality, pass through scheduled mass density
Relationship calculates the volume of the filler of outflow, to obtain the total volume in cement base test specimen all slits region.
Further, further include step before the step S100：
S101, the portion envelops other than several crack areas on cement base test specimen are sealed using sealing element.
Further, further include step before step S1001：
The position in all slits region of S102, label cement base test specimen.It can will specifically generate and there are several
