Abstract:
Commercially available concrete batching and recording equipment, were tested to obtain performance data. Six mixtures were employed using pea gravel (100 percent passing 3/8-in. sieve) to simulate the materials normallv contained in concrete mixtures. A minimum of 500 batches was used to evaluate the weighing and recording equipment,. One material or group of materials was selected from every fifth batch to be weighed to rherk the accuracy of the weighing equipment. These tests form a part of the Corps of Engineers Civil Works Investigations Program.
