  • Autogenous and total shrinkage of limestone calcined clay ...

    2022-1-3 · In this study, the developments of autogenous and total shrinkage of limestone calcined clay cement (LC3) concretes were investigated. Three concrete grades including 25 MPa, 32 MPa and 45 MPa of both LC3 and general purpose cement (GPC) concretes were considered. Compressive strength and tensile strength were measured until curing of 28 days.

    2017-10-30 · As can be seen, the autogenous shrinkage of the samples increases when the dosage of the limestone powder is low (≤30%), but decreases when further increasing the LP content (≥50%). On the other hand, the autogenous shrinkage of mixture LP 30% overtakes that of the reference samples after 1 d, which is in line with the calorimetric results.
