Development in the field of concrete construction during the past two decades has been little short of marvelous. This increase may be accredited to the wide variety of uses to which concrete may be put and to the demand on the part of the American public for construction that is permanent, reasonable in cost, and fireproof. The concrete industry has brought in to the field of labor a new type of skilled workmen and its varied phases each call for men with distinct, definite training. Indications point to a greatly increased demand for men in this line of industrial activity. If the increase in the production of Portland cement during the last few years is reviewed one can easily see the constantly increasing importance with which concrete construction is being regarded. The shipments of cement leaped from 8,000,000 barrels in 1900 to 92,000,000 in 1917. A vivid imagination will not be needed to picture a still greater and wider field for its use in the future.

With the cessation of hostilities new construction work of many kinds is being planned in every section of the country. Millions of dollars will be spent for new buildings, highways, bridges, and various other types of public and private improvements. There will be a demand for trained workmen which will probably tax every effort to supply. A large percentage of the occupations in this line of work can be filled efficiently by men who have suffered some disability in the service of their country. The handicap in the loss of a leg or an arm on the battlefields of France can be overcome with the aid of a “Made in America” leg or arm, fitting the wearer to fill efficiently many occupations in the concrete industry.

A careful study has been made of the limitations imposed by various injuries. There are many cases on record where injured men have overcome all handicaps and have made good in positions which from the survey of the re-educationist appeared quite impossible. Many instances have come to light which show that the statement, “A handicap is merely a state of mind,” holds true for a great variety of cases.

The wage question is no doubt one of the first which arises in your mind. It is natural that one should ask, “What wages or salary does this job pay?” and, “What are the chances for advancement?” In a review of the wages of men engaged in concrete construction as compared with the men engaged in other lines of construction work this fact was noted, that although in 1913 the average wage for the concrete worker was somewhat lower, during the year 1916 wages for concrete workers advanced 60 per cent while for workers in the other line the advance was only 20 per cent. For the man with training in this work the salary will average near $150 per month. As regards opportunities for advancement, few other lines of activity seem to hold forth comparable opportunities, when it is considered that a large proportion of competent workers eventually become partners or managing owners in contracting concerns, while the demand for construction superintendents is usually greater than the supply.

For convenience, concrete-work employments may be classified in three distinct groups, namely: (1) Structural group, including the building of reinforced concrete structures, ships, bridges, dams, retaining walls, and a multitude of small structures; (2) roads and highway group, including the construction of concrete roads and highways, pavements, and alleys; (3) products plant group, including the making of blocks, brick, tile, sewer and pressure pipe, and ornamental trim work.
