This will divide the concrete arch ring into 11 concrete, together with a keystone at the center or crown.  Indoor concrete work such as concrete floors, the making of concrete posts, etc., is quite feasible during the winter providing the temperature where the work is being done does not go below 450 Outside work requires considerable care during cold weather and the aggregates must be properly heated before being used. This is usually done on small work by having a hot fire under a metal arch on which the sand or gravel may be thrown. Warm water should be used in mixing and the finished job properly protected with straw or other materials until it has obtained a sufficient set to prevent freezing. The first step in calculating quantities is to figure the total cubic space to be occupied by the concrete. This is done by reducing all dimensions to like units, such as multiplying length, width or height, and thickness together in feet or fractions thereof.

For illustration, if a walk was to be laid 75 ft. long, 6 ft. wide and 6 in. thick, we would have 75 x 6 x Y2 or 225 cu. ft. dividing this by 27, which is the number of cubic feet to a yard, we have 8 cubic yards as the volume to be filled with concrete. We will assume that we have a house foundation 1 ft. thick, 10 ft. high, 28 ft. wide and 42 ft. long. This would figure 1 x 10 x 26 or 260 cu. ft. for the short concrete wall and 1 x10 x 42 or 420 cu. ft. for the long concrete wall. In the short concrete wall 26 is used instead of 28 because of the figure of the long concrete wall the full length or 42 ft. We must lessen the width, therefore, by 2 ft. (1 ft. on each end) to allow for the thickness of the concrete wall itself, which is 1 ft. Since there are two short concrete walls and two long concrete walls, it is necessary to double the totals 260 and 420, making them 520 and 840, totaling 1,360 cu. ft., from which must be deducted window and door spaces.

Assuming that there are two doors 7 ft. x 3 ft. and eight windows 3 ft. x 2 ft., there must be deducted the following amounts: Two doors would equal 7 x 3 x 1 x 2 or 42 cu. ft., eight windows, 3 x 2 x 1 x 8 or 48 cu. ft., totaling 90 cu. ft. This leaves the total cubical contents 1,360 less 90 or 1,270 cu. ft. It is always necessary, in measuring the height of concrete walls, to take into consideration the depth that the footings or foundations go into the ground and if the footing is thicker below the ground than above, as is quite common, it is better to figure their volume separately. In figuring curved work, such as a road, which is crowned, the average thickness should be taken. Assuming that the earth fill weighs 100 pounds per cubic foot, the lines of division between the 11 sections of the earth fill should each be reduced to or of its actual depth. if we further assume that 160the pavement is a little over six inches thick, and that its weight is equivalent to six inches of solid stone, we may add a uniform ordinate equal to six inches in thickness (according to the scale adopted), and this gives the total dead load on the concrete arch. We shall assume further a live load amounting to 200 pounds per square foot over the whole bridge.

This is equivalent to 2 0% of a foot, or 1 foot 3 inches, of solid masonry over the whole concrete arch. This gives the reduced load line for the condition of loading that the entire concrete arch is loaded with its - maximum load. As another condition of loading, we shall assume that the above load extends only across one-half of the concrete arch. We shall probably find that, owing to the eccentricity of this form of loading, the stability of the concrete arch is in much greater danger than when the entire concrete arch is loaded with a maximum load. We shall also consider the condition which would be found by running a twenty-ton road roller over the concrete arch.
