METHOD FOR MEASURING CHEMICAL SHRINKAGE OF CEMENT-BASED MATERIAL AND APPARATUS FOR MEASURING SAME

摘要

The present invention relates to a method for measuring chemical shrinkage of a cement-based material and an apparatus for measuring the same. According to the present invention, in the method for measuring the chemical shrinkage of the cement-based material, Portland cement and water were continuously stirred during a measurement period, thereby minimizing a lumping effect caused by curing of a cement paste that progresses over time, such that external water is infiltrated into the paste regardless of the thickness of the paste. Accordingly, the whole chemical shrinkage of a sample may be obtained. The temperature of a whole testing body is adjusted in a water bath, thereby allowing measurement in various temperature ranges. Accordingly, the chemical shrinkage of a structure constructed under various weather environments may be measured. In addition, an obtained image is processed in a digital scheme to automatically measure the chemical shrinkage. Accordingly, the measurement is possible by uniformly adjusting a testing period, and the reproducibility and the precision of the result are enhanced, thereby providing convenience.;COPYRIGHT KIPO 2020
