CONCRETE SURFACE STRENGTH MEASURING DEVICE AND CONCRETE SURFACE STRENGTH MEASURING METHOD USING STRENGTH MEASURING DEVICE
To provide a concrete surface strength measuring device determining a surface finish time of placed concrete by measuring a physical numerical value without depending on a specific sense of a floor finisher, and concrete surface strength measuring method using the strength measuring device.SOLUTION: A concrete surface strength measuring device includes a body part having a groove at a tip end, a pressing part stored inside the groove and having a pressing surface projecting from the groove to press a concrete surface, an elastic member stored inside the groove and energizing the pressing part toward the concrete surface, and a measuring mechanism for measuring pressing force of the pressing part pressing the concrete surface. A concrete surface strength measuring method includes: pressing a pressing surface onto a concrete surface, with a tip end face of a body part of the strength measuring device brought into contact with the concrete surface; and determining a finish time of the concrete surface based on a measured numerical value of the pressing force.SELECTED DRAWING: Figure 1
【課題】打設したコンクリートの表面仕上げ時期を、床仕上げ職人の勘に頼ることなく、物理的数値を計測して決定することができる、コンクリート表面の強度測定装置、及び該強度測定装置を用いたコンクリート表面の強度測定方法を提供する。【解決手段】コンクリート表面の強度測定装置は、先端部に溝部を有する本体部と、溝部の内部に収容され、溝部から押圧面が突き出してコンクリート表面に押圧する押圧部と、溝部の内部に収容され、押圧部をコンクリート表面に向かって付勢する弾性部材と、コンクリート表面に押圧させた押圧部の押圧力を測定する測定機構と、を有する。コンクリート表面の強度測定方法は、強度測定装置の本体部の先端面をコンクリート表面に当接させた状態で、押圧面をコンクリート表面に押圧し、測定した押圧力の数値に基づいて、コンクリート表面の仕上げ時期を決定する。【選択図】図１
