 note = {コンクリート床版において，配合および仕上げ時期が床版の表層品質に及ぼす影響について検討した結果，仕上げ剤を用いる場合，Fc27のコンクリートでは凝結始発時間に，Fc36のコンクリートではブリーディングが収まってから仕上げると，表層品質は最も良好になると考えられる．, The durability of concrete slab is apt to be influenced by finish timing of the concrete surface. And the best timing differs with mix proportion. Therefore, the finish timing which is considered the bleeding or the setting time of the concrete slab is very important. However, it is not obvious that relation between the finish timing and the surface properties of concrete. In this study, the effects of the finish timings on the surface properties of concrete slab with the normal portland cement were examined. As a result, in case of the nominal strength 27, the workability, the rebound number and the water absorption velocity of concrete surfaces could be making progress when the concrete slab was finished at the initial set. In case of the nominal strength 36, the workability of finishing was very hard at the initial set by using the finishing agent, therefore the timing of settling the bleeding water was best to finish the concrete surfaces. According to the SEM image, the finish timing of settling the bleeding water was observed more brightly than the timing before settling the bleeding, and it became clear that when concrete slab was finished appropriate time, hardened concrete of surface part became dense.},
