Practical application of the principles of products plant operation discussed in the 1924 report of Committee P-6 was made in a series of tests on 5 x 8 x 12-in. concrete building tile conducted at the plant of the Humboldt Gravel & Tile Co., Humboldt Iowa, and the Structural Materials Research Laboratory, Lewis Institute, Chicago. The tests were made to determine (1) Economical mixes for commercial use, (2) Effect of using concrete at various intervals after mixing, (3) Effect of mixing concrete part time dry and part time wet as compared with mixing continuously wet.
