a provo construction company offers concrete recycling services. chunks of old concrete are pulverized at the construction yard to produce particle-size distributions suitable for aggregate base material. many contractors like this product because the crushing process exposes previously unhydrated cement that will effectively stabilize the base material after water is added. in the laboratory, a sample of reclaimed concrete material obtained from this company was determined to have an apparent specific gravity of 2.59 and an absorption of 5.2 percent. in the field, a layer of this material was determined to have a water content of 9.4 percent by weight of dry aggregate and a wet density of 117.2 pcf. compute the dry density of the layer.
