Unit 9 text reinforced – concrete elements production

With the rapid growth in the employment of precast-concrete products, and particularly of wall panels, slabs, beams, etc., to serve a multitude of building needs, this industry has inevitably incurred an obligation to maintain and improve the quality of the products. A vast amount of excellent work has already been done to raise the standards of this still comparatively young industry to their present level. Machinery and equipment designers have made important contributions by creating better machines and tools for the industry.

A great number of plants producing precast reinforced-concrete elements are now in operation in our country and abroad. Before the decision is made to establish a precast concrete products plant in a given area, a number purely economic consideration deserves particular attention. A careful appraisal of the potential requirements provides valuable information for determining the size of the plant which should be built. A well-designed plant must have sufficient capacity for the normal output plus a reasonable margin for a possible increase. The design should specifically and carefully anticipate the future installation of additional equipment for increased production without disrupting the original lay-out.

It is axiomatic now that materials can be handled more cheaply with machinery than with manpower. At present the trend is definitely toward the practice of elevating all raw materials into overhead storage bins. For obvious reasons, it is preferable that the elevation be sufficient so that the materials may move by gravity from the bins to the mixers and moulding machinery without re-elevating. With such an arrangement the mixers are located on a separate floor level directly above the mouldig machinery.
