Internal curing of high strength concrete based on saturated microporous cenospheres
Case Studies in Construction MaterialsThe development of high-strength concrete is hindered by its substantial autogenous shrinkage. However, the implementation of internal curing technology has been shown to mitigate this autogenous shrinkage of concrete effectively.

Shape correction factor for drying shrinkage in a concrete cross-section [PDF]
, 2015 A concrete member is subjected to loads for a long period of time, during which creep and shrinkage of concrete develop gradually. The prediction of this time-dependent behaviour is important as it may cause serious serviceability problems in concrete ...

Journal of Clinical Periodontology, Volume 53, Issue 2, Page 299-307, February 2026.ABSTRACT Aim To test the hypothesis that a volume‐stable collagen matrix (VCMX) can serve as an effective rhBMP‐2 carrier for bone regeneration while compensating for the volume instability of absorbable collagen sponge (ACS). Materials and Methods (i) rhBMP‐2 release kinetics from VCMX and ACS were measured over 7 days by enzyme‐linked immunosorbent ...

Autogenous Shrinkage of HPC and Ways to Mitigate it
Key Engineering Materials, 2014 Autogenous shrinkage strains may cause cracking of brittle cement-based systems. The lower the water/cement ratio of a mixture, the higher the autogenous shrinkage and the higher the probability of cracking. Cracking increases the probability of ingress of aggressive substances into the concrete, jeopardizing the durability of the material.

Effect of external expansive agent addition on the strength and shrinkage deformation of UHPC [PDF]
E3S Web of ConferencesThis study explored the dosage-dependent influence of two types of external expansive agents on the strength, early-age autogenous shrinkage, and drying shrinkage deformation of ultra-high-performance concrete (UHPC). By analyzing the impact of expansive

Self-desiccation and self-desiccation shrinkage of silica fume-cement pastes [PDF]
, 2017 Self-desiccation is one common phenomenon of high-performance cementitious materials, which are characterized by low water/binder (w/b) ratio and high mineral admixture incorporation. As a consequence, large magnitude of self-desiccation shrinkage, a key

Extrudable Reactive Powder Concretes Hydration, shrinkage and transfer properties [PDF]
, 2012 International audienceThe behavior of five reactive powder concretes (RPC), with four of them being extrudable, has been studied since the first minutes up to more than 90 days. The extrusion force, hydration rate, free autogenous shrinkage at early age,
