Abstract:
Crushing strength-age relationships for several mixes of concrete made with different aggregates cured out-doors, under water, and in air indoors feature this re- port. Over 2000 concrete cylinders, also many auxiliary mortar specimens for strength-age determinations and absorption, freezin and expansion tests are included. l and thawing, Ana ysis of cements are listed. For the outdoor and underwater curing conditions the strength of the concrete increased approximately as the logar- ithm of the test aqe up to 20 years, for the indoor storage no 3 months. increase-in concrete strength occurred after
