LIGHTWEIGHT CONCRETE FLOOR SLAB WITH EXPANSION MATERIAL, AND CONCRETE CASTING METHOD
To provide a lightweight concrete floor slab with expansion material and the like capable of improving durability and weight reduction at low cost.SOLUTION: A road structure 3 includes a floor slab 31 and a pavement layer 35. The floor slab 31 is formed of concrete. The concrete is lightweight concrete with expansion material that contains expansion material added to the light-weight aggregate and cement. The amount of expansion material is 0.75 times or more and 1.1 times or less of the standard mixture amount, and the water binder ratio of concrete is 30% by weight or more and less than 38% by weight.SELECTED DRAWING: Figure 1
【課題】耐久性向上と軽量化を低コストで実現可能な膨張材併用軽量コンクリート製床版等を提供する。【解決手段】道路構造３は、床版３１と舗装層３５とを有する。床版３１はコンクリートにより形成される。コンクリートは、軽量骨材およびセメントに加えて膨張材を含有する膨張材併用軽量コンクリートである。膨張材の量は、標準混和量の0.75倍以上1.1倍以下であり、コンクリートの水結合材比は、30重量%以上38重量％未満である。【選択図】図１
