Chemical shrinkage and autogenous shrinkage of Portland cement—metakaolin pastes
Advances in Cement Research, 1998Portland cement (PC)-metakaolin (MK) pastes of compositions 0, 5, 10, 15, 20 and 25% MK and water/binder ratio 0·55 have been subjected to tests for chemical shrinkage, autogenous shrinkage and expansion during soaking. Chemical shrinkage was carried out in 200 ml containers on water-covered 12 mm thick layers of paste, and the volume changes were ...

Autogenous Shrinkage in Plain Cement Mixtures
Key Engineering Materials, 2008Determination of a realistic model for the estimation of autogenous shrinkage in plain cement mixtures has been an ongoing research among researchers in high performance concrete. While no standard test method exists for the determination of autogenous shrinkage, various researchers have designed different test methods for measurement of autogenous ...

Roadmap for autogenous shrinkage control of UHPC
2021Ultra-high-performance concrete (UHPC) demonstrates extremely large autogenous shrinkage due to its high content of cement and very low water-to-binder ratio (w/b). Many techniques can be used to mitigate the autogenous shrinkage developed in cement-based materials. Based on their action mechanisms, they can be classified into the following categories:

An Experimental Study of Autogenous and Drying Shrinkage
2017Shrinkage of concrete is the time-dependent strain in an unloaded and unrestrained specimen at constant temperature. It is usually considered to be the sum of drying shrinkage and autogenous shrinkage. Drying shrinkage is the reduction in volume caused principally by the loss of water during the drying process and this continues perhaps for years after
