Concrete From Sand Molds e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. The low cost of molds, using simply the cheapest and most common of materials; the ease and rapidity with which work may be produced; the increased density and strength of the concrete; perfect details to the lines of ornamental designs, together with the perfect curing of the work without the least attention, as it remains enclosed by the wet sand until the final set or hardening of the cement has taken place; these facts alone are convincing that this process is not only the one probably first employed in this work, to produce orna mental efiects in concrete, but will be the first in efficiency at the present day to enable the concrete worker to mold any design he may desire, without restrictions as to releasing the mold from the finished work.
