This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 Excerpt: ...probable cost of forme I find the following method most reliable: First, after ascertaining the time limit within which the work must be completed, determine the number of cubic yards of concrete that must be laid each day, after allowing liberally for delays. Knowing the number of cubic yards, estimate the number of thousand feet board measure of forms required to encase the concrete to be placed in a day. This will give the minimum amount of lumber required, for it is never permissible to move the forms until the concrete has hardened over night. This brings us to a very important question in economics. Thousands of words have been written on the advantages and disadvantages of using "wet" or "dry" concrete, but I have never seen mention of one of the most forceful objections to the use of concrete mixed so wet that it is sloppy. I refer to the slowness with which such concrete hardens. Obviously, the more slowly it hardens, the longer must the forms be left in place; and the longer the forms are left in place the more lumber will be required; the more the lumber, the greater the cost of forms per cubic yard of concrete. A concrete mixed "dry," and rammed, will harden over night, so that in retaining wall construction it is safe to remove the forms the next morning; but, where the concrete has been mixed "sloppy," I have seen whole sections of wall fall out upon the removal of forms twelve hours after placing the concrete. In cold weather the setting is further delayed, and in very cold weather it may cease entirely unless proper precautions are taken. Specifications relating to sloppy concrete usually provide that wall forms shall not be moved within 48 hours after placing the concrete; but in hot weather it is oft...
