To quickly assess the difficulty of the text, read a short excerpt:
Va first heated the rile of sard and gravel, by means of a steam hose atliached to the boiler of the concrete mixer, After the sand was well heated, we turned the steam into the water, and then started to mix the concrete. In this way the sand, gravel ano water were hot, and this made the concrete wanrt when it was placed in the forms, and would thus set before freezing. The only other pre- cautions taken were to keep Ura snow and ice off the Page 10. top of the walls and keep the sun off the c...oncrete until it was v/ell d.ried out, We found that if the concrete once had set before freezing and ^vas not allOTred to alternately thaw and freeze, we had no trouble. I would not, hw/ever, assert that this is safe practice, As little ivater as possible is used in cold weather. In reinforced -jork such as hollow tile floor construct in, the added precaution of plac- ing coke fires in salamanders below the f Jjoor should be taken, and the slab covered "/ith a foot and a half of straw. If the weather is very cold j t Is good prac- tice to keep the coke fires going for a yeriod of three or foirr days.
