REQUIRES CONCENTRATION: A job as technical as this machinery would indicate appears to be requiring a lot of concentration by these two boys. The pair--Johnny Malott (left) and Donnie Spragg--are shown as they "supervised" operations yesterday at the Ann Arbor Construction C. parking lot at 221 Felch St. The equipment at the left, razing of which was begun yesterday, was used in the making of "heavy" concrete in the construction of a University atom research building.

CENTER OF OPERATIONS: This tower is the center of operations in a transit mix concrete plant. The crane is depositing stone which, along with sand, constitutes the "aggregates." In this tower, stone, sand, water and cement are mixed by weight (volume in the case of water) and deposited into the waiting truck seen underneath the tower. The blended ingredients are mixed en route to the job.

Here, asphalt or bituminous concrete is made of sand, stone, fly ash, water and asphalt cement. The firm has three other similar plants - one near Pontiac and two portable plants.
