Scofield R. C. Fitch Dr. Fe. C,. Alien Department of Physical Education University of Kansas Dear Dr, Allen: Attached is a rather hurried estimate on approximate costs to build one reinforced concrete tennis court. This estimate is based on plans and specifications of the Portland Cement Association and in line with suggestions of Jx.Coen, who has written me quite fully. The cost may appear quite high and on an actual competitive bid it is quite likely you could get it done somewhat cheaper, although there is always the doubt if you would get as good a job as could be done by Buildings and Grounds, This work is quite similar to our reinforced concrete walks, which cost about 25¢ per sq. ft. finished. On this basis this cost would be 6720 sqe ft. at $ 0.25 = $1680.00, which is almost the same as above estimate. Junior Coen mentions a double court they built in Kansas City which cost $2500.00. The double court could, of course, be built somewhat more economically than a single court. In this estimate, nothing is included for the wire back stops or the tennis net. The construction, to be satisfactory, will have to be very carefully done, particularly regarding grades and surface finishing. I am getting other information on courts built on the west coast, and may have some changes to suggest later on. I trust this estimate will be of some service to yous Yours truly, ia — F, A.

Proportioning (Water-Cement Ratio Method) a.- Concrete shall be mixed with not more than six (6) U.S. gallons.of water per sack (94 lb. net) of-ce- ment. Surface water carried by the aggregates must be in- cluded as part of the mixing water in determining the amount of water to be added to the batch. Note: The quantity of mixing water used in each one sack batch shall not exceed 6 gals. with dry sand and 5 gals. with wet sand. The water should be carefully measured to secure uniform batches. Limiting the mixing water to these requirements will insure strong dense concrete which will resist effects of weather and will provide a good wearing surface. b. The coarse aggregate shall be not less than the amount of fine aggregate nor more than twice the amount of fine aggregate. Cc. Fine and coarse aggregates shall be used with the specified quantities of cement and water in such proportions to produce concrete that will work readily into the corners of the forms and around the reinforcement without excessive puddling or spading and without permitting the materials to segregate or water to collect on the surface. 18...

CONCRETE BUILDER Volume 6 Yo se EE - z SEEN MP RL OLE: ‘ 3 — Number 4 ishediby Publ Portland Cement Association “Concrete for Pccmvihenve and Firesefety me oR CONCRETE BUILDER Building Black-Colored Concrete Tennis Court with White Mortar Playing Lines By ALFRED SIMMONS Foreman, Bulley & Andrews, Concrete Contractors, Chicago, Ill. court which we built for the Uni- versity of Chicago has several fea- tures that will interest concrete contrac- tors. The plans, which were prepared by the building and grounds department of the university, called for black con- crete topping that would prevent glare from bright sunlight. The playing lines were to be of white cement mortar which would not need constant repainting. The surface was to have a mat- or canvas- like finish. The drainage system was to be different in that surface water was to be collected and carried away without allowing it to run over the edges of the slab or over the next court. All of these features interested me, and I could see that here was a chance to build something new in tennis court construction. at a black-colored concrete tennis Construction Details - N beginning this work we set stakes (about 10 ft. apart both ways) to the finished grade which allowed for a slope of 2 in. to one side. Next we laid 6-in. drain tile around the outside of the court, connecting it to the storm water drain. About 8 in. from the edge and near the net post on the low side of the court, we built up a riser pipe to pro- vide an outlet for the integrally formed gutter along the outer edge of the con- crete slab. Then we placed the base for the net posts. This was done early so that the forms could be taken off when we built the slab. After the surface of the old court was removed to 5 in. below the top of the grade stakes, we set the forms which con- sisted of 2-in. material. They were set along the single court playing lines, con- tinuing out to the edges of the court. In this way, the concrete slab was built in sections corresponding to the play- ing lines. Alfred Simmons To make the grooves for the white concrete playing lines, we used 2 by 2-in. wood strips beveled on one side to per- mit easy removal. These were lightly nailed to the form boards. For the double court lines, the 2 by 2’s were notched into the top of the cross forms and supported in between on small wooden stakes. Later, when the strips were pulled out, we drove the stakes down and filled the spaces with white portland cement mortar. All sections of the court were rein- forced with large-mesh metal reinforce- ment weighing 78 lbs. per 100 sq. ft. To tie adjoining sections of the concrete together and keep them even, we placed ¥%-in. round bars, 30 in. long, about 3 ft. apart in all construction joints. The work was laid out so we could keep going without having to work over any of the completed slabs before they were at least two days old. For the concrete in the 5-in. slab, we used a 1-214-314 mix for the base and a 1-214 mix for the top. To get the color in the topping that the inspector wanted, we. used 1 gal. of specially prepared liquid black mineral oxide to each sack of portland cement. We placed concrete that was quite stiff yet workable. I mean “placed” not “poured’’ because the concrete we used wouldn’t pour, but re- quired placing. I have found that quite stiff concrete can be worked into place easily when the mix has enough sand in it. Where the concrete is placed sloppy, the finishers are always delayed and more time is required to work out the high and low spots left when the excess water gets away. Speeding Up Work O speed up the job, we waited until two sections of the base course were filled, leveled and tamped before we put on the black-colored topping. We struck off the topping, wood-floated it and then steel-troweled it sparingly. Finish trow- eling was not needed since the court was to have a mat- or canvas-like finish. To get this finish we brushed the top both ways with a long-handled floor brush just as the water sheen disappeared from the surface. The brush had hair bris- tles. I found that if a brush is used too soon, the surface smears over; if too late, the brush will not score the surface. The right time to do this brush- ing, we found, was just when we wanted to go to dinner or go home at night, but we always stayed to complete th job. Curing Important E have found that it pays to cure concrete carefully, especially on high grade colored jobs or surfaces which will receive a lot of wear. As quickly as the surface was hard enough so it wouldn’t mar, we covered the finished sections with heavy waterproof paper to keep the concrete from drying out. After the last slab had cured for four days, we took off the paper covering and cleaned and washed the court with clear water. We waited for the wood strips in the marking lines to dry out before we attempted to remove them. In this way, we made sure that the edges of the slabs would not be damaged. We cleaned the grooves and surface of the concrete after the strips were taken out. White Playing Lines HE next step was to dampen the bottom and sides of the grooves with a whitewash brush and water. Then we filled the grooves with a mortar made of 1 part white cement and 2 parts coarse white sand. The mortar was mixed quite stiff. We tamped it thoroughly in place to make sure that the grooves were com- pletely filled. Care was taken in plac- ing the white mortar not to smear any of it on the black surface. The edges of all slabs and the white marking lines were finished with an Colored topping being placed over concrete base which is tamped to compact it.

We found that by running the edger first along the hardened concrete (Below) Finisher doing rough steel-troweling immediately after topping has been floated. that the white mortar is forced away from the black concrete top and then, when the white lines were edged, we had a clean, sharp break between the two colors. We covered the mortar in the marking lines with waterproof paper and let it cure for several days. Then we wet the entire court several times a day for a week, after which it was opened for play.
