UNIVERSAL PORTLAND CEMENT CO. .-1 Time Required to Build Concrete Silos ditions of weather, and the height of wall accommodated l).v the forms at a single filling. Where the work is done by home labor occasionally more than 2 weeks are required. The block silo can usually be put up in 4 days to a week, depending upon its size and the number of block masons employed. Alter com- pletion it should be allowed to stand at least two weeks before filling, to allow the mortar to become firm and hard. Cement stave silos are commonly erected complete in 3 days, and cement plaster silos in about a week. If the silo is to be filled during the early part of September, work on the foundation should be commenced no later than August 20th. In all cases the silo should be completed two weeks before being subjected to the strain caused by filling. Two general methods of concrete construction are available for silo work—the monolithic and the concrete block. With the former method, the materials are hauled to the site of the silo and there mixed and placed within forms; the latter method requires that the block be made and cured in some convenient place, and later hauled to the site to be laid up in the wall. Each method has certain advantages and disadvantages, but the matter of personal choice generally influences the decision to build either with monolithic walls or with block. The monolithic silo is generally the easier of the two for inexperienced persons to build, and is usually a little cheaper than the block, as it does not require the service of good masons or the use of a block machine; the block silo, however, makes the use of forms unnecessary, produces a wall with continuous vertical air spaces, and slightly reduces the amount of materials used.
