1912 The Edison Aggregate COPYRIGHT 1912 BY THE EDISON PORTLAND CEMENT CO. T HE photograph reproduced above shows a type of concrete floor con- struction which has been developed by The Concrete Products Co. of New York and known as "Ribcrete” to meet the demand for a low priced fire-proof floor for dwellings, factories, garages and other buildings. The joists are placed not to exceed 18 inches on centers and are set, framed and finished without the use of wooden centers and without concrete mixed on the site. After the joists are set in place, the ceiling slabs are set on the lower bevel and grouted in. Holes 5 inches in diameter spaced 17 inches on centers are left in the web of the beams both to lighten the construction and to facilitate the running of pipes, conduits, etc. The entire construction is light enough to be readily installed by hand with unskilled labor without the use of derricks or other mechanical devices. Where a wooden floor is to be laid, furring strips are fastened to the upper side of the joist before being sent to the building. The “Tilecrete” residence shown on the cover was designed by C. Ritter- busch. Architect, Cqncrete Products Co., manufacturers of “Tilecrete.” ✓ #\vERY CGLl OLD MINT BUILDING (Reinforced Concrete) 37-39 N. 7th St., Philadelphia Edward S. Bertolett, Architect W.

EDISON PORTLAND CEMENT USED EVERLASTING WATERING TANKS M ANY PERSONS want to know how to build their own concrete water- ing tanks and troughs. The method is easy and a tank is not expen- sive. To explain the plan, a tank is described below which holds 30 barrels of 31p> gallons each. If desired, smaller or larger troughs, round or square, may be built in exactly the same manner. Such tanks, well made, never crack, wear out or cause mudholes. To build a tank like the one shown in the picture mark cut the ground plan 5 by 14 feet. Within these lines scrape away all trash and dig a founda- tion trench 10 inches wide and 2)4 feet deep around the entire tank. Lay all in-flow and overflow pipes (not less than l l /> inches in diameter) so that the ends, fitted for connections, will be even with the finished bottom of the tank. Concrete Tank with Removable Tank Heater Before digging the foundation trench, build the forms and have all mater- ials on hand. For forms use 1-inch siding on 2-by-4-inch uprights spaced 2 feet apart. The outside form is a bottomless box o feet wide by 14 feet long, inside measurements. Make it 3 feet high to provide for a 6-inch floor and a clear depth of 2 l /> feet. The inside form must be narrower and shorter to make provision for walls 5 inches thick at the top and flaring to a thickness of 8 inches at the bottom of the tank. When ice forms, this slope allows it to slip up the tank walls instead of pushing directly against them. The sides , and ends of the forms may be made separate and put together in place; or i each form may be entirely completed and set up as one piece. The forms are j held in position by 2-by-4-inch liners at top and bottom and, if necessary, j by sloping braces nailed to stakes driven in the ground, Cut strips of heavy ! woven wire fencing long enough to cover the bottom of the tank crosswise and to project up into the walls to within 6 inches of the top, and likewise a strip 4 feet longer than the inside length of the tank. With the forms ready, mix the concrete, 1 part Portland Cement to 2 parts 1 sand to 1 parts crushed rock. In measuring the materials, count 1 bag of ' cement equal to 1 cubic foot. If bank-run gravel is used, mix the concrete, 1 j part cement to 4 parts gravel. Fill the foundation trench with concrete. Set the outside form in place. Sec that it is level, so that the tank will he level ; and can be entirely filled with water. Lay the 6-inch bottom reinforced \/i j inches from the under side with the short lengths of woven wire crosswise and 1 ]/z inches from the upper side with the long strip of fencing. Bring up the extra length of wire so that the ends will project up into the future side- walls and can be fastened to the reinforcing rods. (This wire reinforcing in the bottom will prevent possible cracking due to heaving by frost.) Finish the surface of the bottom the same as for a sidewalk. Do not let concrete get into the in-flow and over-flow pipes. Cross Section Showing Forms and Tank with Reinforcement W ith the bottom finished, immediately set the inside form in place and fill the wall space with concrete mushy wet. Half-way up the side, and 1 inch from the outside, lay a 3/6-inch rod (or several hooked together) entirely around the tank. Again 2 inches from the top and 1 inch from both inside and outside, imbed two more jBj-inch rods in the concrete. Round the top edges of the tank with a trowel or a sidewalk tool. If a tank cover is desired, insert Id-inch bolts, heads down, in the soft concrete with sufficient length above the top of the wall to pass through the wooden cover and to receive a nut and washer. \\ hen the tank is three days old, remove the inner form and paint the inside of the tank with a mixture of cement and water as thick as cream. Screw into the over-flow connection the necessary length of over-flow pipe. 1 he tank may be used in ten days provided the outside form is left in place. If the outer form is removed at the same time as the inner, do not use the tank for two weeks.

New York EDISON PORTLAND CEMENT USED GATE BOX FOR THE CITY OF BOSTON D URING the past year, Charles J. Jacobs Company, Boston, have used about 1,000 barrels of Edison Portland Cement in making meter, Post hydrant, lowery, blow-offs and gate boxes for the City of Boston. The proportion of concrete used is one, two and four with reinforcements of quar- ter-inch twisted steel. The photograph reproduced above is one of the gate box. The slab was one and three-quarter inches thick ; the total area of the slabs 35.7 square feet. 125 pounds Edison Portland Cement 250 “ Charles J. Jacobs Co.’s Medfield Sand 500 “ washed stone 07.8 lineal' twisted J4" steel .7 “ of No. 13 guage galvanized wire The boxes were made to take the place of tile old wooden ones which were used by the City of Boston and which in time decayed. These boxes were left in forms for seventy-two hours; were taken out, stored for three weeks when they were shipped. There was no breakage in the shipments, and some of the boxes were used immediately and set in the ground and have given good satisfaction. EDISON PORTLAND CEMENT USED TEN GOOD REASONS WHY YOU SHOULD USE Edison Water-proofing Paint 1. It is colorless and does not stain. 2. It is easily applied at any time. 3. Mixed with a fast evaporating oil, it penetrates the surface and stays in the mass ; not on the surface as a skin. 4. It is economical ; one gallon covers (2 coats work) from 90 to 135 square feet of surface. 5. It is permanent. The surface once treated, remains water-proofed forever. 6. It is not attacked by weather, rain, frost, acids or alkalies. 7. It prevents disintegration of soft brick and when used as a “filler” insures a smooth even coat to the paint which may afterward be applied. 8. It prevents efflorescence on brick or concrete. 9. It prevents staining of joints in masonry. 10. Because it is used by the U. S. Government after exhaustive tests of other so-called water-proofing Paints and Compounds. DIRECTIONS 1. No expert is needed to apply it, as it is put on with a brush like any other paint. 2. The surface must be dry and carefully brushed with a stiff brush or a broom. 3. The material should be carefully brushed in and the second coat not applied until the first is dry. For ordinary concrete or stucco, two coats are sufficient. If the wall is very porous, more may be required. 4. As this material is transparent, do not expect it to remove or cover up stains. 5. Shake the can before using, and if it is not transparent, but cloudy or milky, stand in a warm place for a few hours. Should it not clear readily, stand the can in hot water or on steam pipes, etc., but do not bring it near an open flame. 6. Have plenty of ventilation where it is used. 98% THRU 100 85% THRU 200 UNIFORMLY 10 % FINEST GROUND IN THE WORLD The Cement of National Recognition MARK PORTLAND CEMENT .
