FISRT: Before posting PLEASE clean up the SUBJECT line (remove all the [SEAOC] things) so it will be easier to read the SUBJECT line. Have you ever tried to find the Subject when there is 48 chars of garbage first? (Garbage = [SEAOC] Re[SEAOC] Re ... etc) THEN CONCRETE CRACKS: Normally cracs due to plastic shrincage is limitet in length (up to a couple of meters), remark that i say normally - there is times you get long cracks. Shrinkage cracks has often a relative long length (relative to the structure), for instance normal to the length of the structure and all across it. On a slab on grade you will normally get plastical shrincage crakcs at a 45° angle (with some exceptions). Shrinkage cracks will normally go paralell or normal to the structures main lines (depending on the structure support and whats on top of it.) Cracks due to external forsec (included erthquake) cracks get different directions according to the type of forces and how/where the attack. All types of cracks start at the week point of the strukture, for instance corners - holes etc. The trouble regarded with evaluating cracks is that You often have to see them (visual) to evaluate them. An idea in this matter is that if You have a picture/diaphgram etc. you man put them on WWW and post the URL here. Pleace do not attach pictures as some people pay for bytes mail received. (and there is always problems with conversion etc.) ____________________________________________________________________________ Mr. Øyvind Sæter (Alternative: OEyvind Saeter) M.
