| Popis: | Test method for compressive strength of BOSS specimen is provided for NDIS 3424. However, test method for static modulus of elasticity of the BOSS specimen is not provided. In this study, static modulus of elasticity of the BOSS specimens using ordinary portland cement and blast-furnace slag cement class B were compared with core specimens. As a result, compressive strength and static modulus of elasticity of the BOSS specimens and the core specimens were almost the same, and it is considered that the static modulus of elasticity can be measured by sticking two strain gauges diagonally on the surfaces of BOSS specimen. If it is difficult to stick strain gauge on the top surface which reminded track of crater, two strain gauges should be sticked on the side surface and the split surface of BOSS specimen diagonally. 本研究では，普通ポルトランドセメントまたは高炉セメントB 種を用い，ボス供試体とコア供試体の静弾性係数を比較した．そして，ボス供試体を使用して構造体コンクリートの静弾性係数が測定できるのかどうか検討した． |
