Findings from the Use of Compensated Shrinkage Portland Cement in the Lodi Free- Way Experimental Pavement
An experimental portland cement concrete pavement section designed to evaluate concrete using a type of expanding portland cement referred to as 'compensated shrinkage cement' was incorporated into a Central California highway project known as the Lodi Freeway, in the summer of 1963. This was the second project of its type. The compensated shrinkage cement used on these projects was formulated to produce an expansion to offset or compensate for the drying shrinkage that normally occurs. The concrete in each of the six 1/4-mile units of the Lodi experimental pavement was placed monolithically with no expansion or contraction joints. Pavement and anchors were used in the compensated shrinkage cement units. The only discontinuities were the construction joints at the ends of the 1/4-mile units. Related factors evaluated in conjunction with the use of the special cement were: the effect of air entrainment and the effect of a moist earth blanket cure compared to polyethylene sheet cure. Evaluation of the behavior and the properties of concrete in the experimental sections was aided by the use of Carlson electrical strain gages embedded in the concrete, surface gage points, crack surveys, and testing of field fabricated test specimens.
