Developing a Low Shrinkage, High Creep Concrete for Infrastructure Repair

Investigations to develop a durable concrete full depth pavement repair mixture with a four hour cure time and 4000 psi compressive strength that will minimize cracking were carried out. Current high early strength concrete mixtures have natural cracking and shrinkage problems due to the high content of cementitious material or their chemical components. Using Internal Curing (IC) allows for early strength, enhanced durability, reduced shrinkage and providing water that can be absorbed by the cement paste after the final set. Different ordinary portland cement (OPC) and calcium sulfoaluminate (CSA) mixtures were prepared, with and without IC. Mixtures with IC had reduced early strength and delayed hydration, however, when combined with CSA cement, were able to obtain about 4000 psi of compressive strength in 4 hours of curing. Significant improvements in volume stability were also noted in the IC mixtures. Drying and creep shrinkage were reduced by factors of up to 15% and 30%, respectively. A CSA mixture with IC is recommended by the authors.
