Abstract : Leading manufacturers of concrete batching and recording equipment were contacted to determine various types of new or improved batching and recording devices available for evaluation testing. The tests were conducted, except for one, at the 2-cu-yd-capacity batch plant of the Waterways Experiment Station. Six mixtures were employed using pea gravel (100 per cent passing 3/8-in. sieve) to simulate the ingredients normally contained in concrete mixtures. A minimum of 500 batches was used to evaluate the weighing and recording equipment. One ingredient or group of ingredients was selected from every fifth batch to be weighed in order to check the accuracy of the weighing equipment. (Author)
