U bars are mainly used for arresting bursting stresses. In conventional structures they are used at supports mainly. In Pre-Stressing structures, they are used adjacent to anchorage set up on both sides. If your question is specific to a structure, we may elaborate the explanation. Thank you!

From the picture posted, the following may be the reasons, 1)The flood level of that region may be higher than normal building level at times of season. 2)The basement level to be filled upto the level of brickwork, so to draw seepaged water, pipes can be installed. 3)Other aesthetic reasons...

It's chair rod.

During casting it hardens from bottom. During curing, the surface hardens(irrespective of bottom or top). In general, the open surfaces get harder first as the bottom shuttering takes time to get removed that top and sides.

By commonsense: No issues. We can use. By specifications: We cannot use steel bar. B'coz tamping rod is made at a standard dimensions.

Obviously yes! One of my batchmates has done it.

Based on mix design and w/c ratio it changes. For standard mix design, it can easily taken from standard ratio. Otherthan standard mix design like M30, w/c ratio can be from 0.45-0.50, which requires 160L-180L of water.

It doesn't mean humid or rainy but the important thing is curing the concrete often. If the Nature does the job, fine, if not curing should be continously done. Concrete absorbs/utilize only certain amount of water. So if the concrete surface is dry, curing should be done.

Thank you for the document sir...
