摘要： PURPOSE:To manufacture a concrete composition which can eliminate or simplify the process of vibrating compaction and fill densely upto the corners of a mold and can be manufactured by an existing plant and equipment and existing materials. CONSTITUTION:In a concrete composition composed of a cement material containing at least rough aggregate, small aggregate, water content and a high performance AE water reducing admixture, the water to bonding material ratio (W/C) is 35-41% when the cement material is represented by C and the water content represented by W, and the small aggregate rate (S/A) is 45-55% when the aggregate is represented by A and the fine aggregate in the whole of aggregate is represented by S, and the unit water amount (W) is 165-175kg/m. Said concrete composition is of high fluidity and provided with superior deformation properties and resistance to material separation.

摘要： PURPOSE:To produce concrete having strength close to the limit of lightweight concrete by using a high-performance water reducing agent, making a specific weight ratio of water/cement and an amount of air and blending a concrete base with an artificial lightweight aggregate utilizing a specific surfactant. CONSTITUTION:A high-performance water reducing agent is used, a water cement ratio of mortar is 15-35%, water gap is almost removed, a sulfuric ester salt, sulfonate or ethylene oxide adduct of nonylphenol is used as a surfactant to give aerated mortar providing wall surface with slight unevenness and having excellent balance of strength and lightweight further by limiting an amount of air to 20-40vol.%. The aerated mortar is blended with an artificial lightweight aggregate to produce high-strength lightweight concrete.

摘要： PURPOSE:To more remarkably enhance strength than that of conventional cellular mortar and obtain a concrete having a strength close to the limit of lightweight concrete but with a further light weight by carrying out quantitative analysis of cells and water voids contained in the interior of the cellular mortar. CONSTITUTION:The aforementioned high strength cellular mortar has water voids of the following shape. That is the average value of roundness [(cell perimeter) /{4pi(cell area)}] of cells having >=50mum size (maximum chord length) exposed to a cut surface is =50mum size (maximum chord length) exposed to the cut surface is and the number of cells, having perforated walls and exposed to the cut surface is =50mum size (maximum chord length). The above-mentioned mortar is kneaded with an artificial lightweight aggregate to afford high strength lightweight concrete.

摘要： PURPOSE:To prevent cracks in the positions except extensible joints, even in an external concrete wall fitted at the front end of a handing floor slab of a building. CONSTITUTION:Tiles 16 are neatly laid down on the outside face of an external concrete wall 14 of a building 10. A handing floor slab 26 is extended at the outside end of the inside floor slab 24 of the building 10. The external concrete wall 14 is attached to the front end of the hanging floor slab 26. Extensible joints 25 of the post center are provided in the vertical direction at the opposite position to the post center P of columns 18 of the external concrete wall 14 and ordinary extensible joints 28 are provided with a specified interval between the extensible joints 25 of the post center of the external concrete wall 14. Accordingly, cracks are concentrated at the extensible joints 25 of the post center and the ordinary extensible joints 28 and hence, cracks in the positions except the extensible joints are prevented.
