Relationships among degree hours of maturity and compressive strengths of untreated, 1 to 3-day-old concrete cylinders are used to develop equations for predicting minimum potential 28-day strength. The one-sided confidence limit on values is approximately predicted at f - 600 psi (f - 4140 kPa). From the results of early tests, one equation produces predicted values for mixtures of the known maturity and the known cement factor, one requires only that specimens be tested at a constant maturity… CONTINUE READING
