The early strength of the concrete can be increased if it is kept damp during the curing process. Minimizing stress prior to curing minimizes cracking. Highearlystrength concrete is designed to hydrate faster, often by increased use of cement that increases shrinkage and cracking. The strength of concrete changes (increases) for up to three

5.1 Care must be exercised in the interpretation of the significance of compressive strength determinations by this test method since strength is not a fundamental or intrinsic property of concrete made from given materials. Values obtained will depend on the size and shape of the specimen, batching, mixing procedures, the methods of sampling, molding, and fabriion and the age,
CONCRETE MIXING RATIOS Everything About Concrete
Concrete mixing ratios for cement, sand, aggregate, and water are generally mixed as 1 part cement, 3 parts sand, and 3 parts aggregate or stone with just enough water to make it workable. The ratio of aggregate to sand to cement is an important factor in determining the compressive strength of the concrete mixture.
