This study is conducted an experiment to unifyprovide a method to estimate the method of measuring the condensationsetting time and estimating the initialearly age compressive strength using the existingD type ddurometer. into a single device and to adopt the best estimation guidelines of the estimator. As a result of the experiment, Test results indicated that it is analyzed that the use of D type Durometer attached with modified needle, which was designed to secure improved accuracy in setting and compressive strength, enables to estimate it is possible to estimate the condensationsetting time of mortar and estimate the compressive strength ofat early age. the initial age when the estimation No. 2 is adopted for the Durometer D type.
