...Tara L. Cavalline; Ross A. Newsome; Brett Q. Tempest; Jacob W. Leach Internally cured concrete has been shown to help mitigate early-age cracking and to provide improved durability performance in concrete elements. The increased absorptive capacity of lightweight aggregates (LWA) facilitates...

... that internal curing with saturated lightweight aggregate would prevent or delay restrained shrinkage cracking in the rapid repair media. The fresh properties (slump, setting time), mechanical properties (elastic modulus, compressive and tensile strength), and volume stability (autogenous shrinkage, drying...

...B. J. Mohr; K. L. Hood This research aims to answer several outstanding questions that must be addressed before internal curing materials can be commonly used in structural concrete. The wide range of possibilities for internal curing material properties can dramatically alter the effectiveness...

...Matthew J. Krafcik; Baishakhi Bose; Kendra A. Erk The objective of this research is to define the fundamental structure-property relationships of water-swollen polymer hydrogel particles that are employed as internal curing agents in cementitious mixtures, in addition to reporting a novel synthesis...

...Rouzbeh Khajehdehi; Muzai Feng; David Darwin; James Lafikes; Eman Khalid Ibrahim; Matthew O’Reilly Internal curing (IC) using prewetted lightweight aggregate (LWA) has often been used to improve the cracking performance of concretes with low water-to-binder (w/b) ratios (<0.42) when autogenous...

... the possibility of including internal curing (IC) in cementitious grouts with the aim of partially reducing or mitigating most of the shrinkage observed in these materials. The research discusses the particularities encountered in designing IC cementitious grouts, as opposed to conventional concretes...

... as a new natural plant-based internal curing agent in cement paste and concrete. For the concrete specimens, the primary focus was on workability effects and compressive strength. In the concrete study, twelve batches with different CNF volumes were prepared, and the corresponding slump results were...

...Luca Montanari; Prannoy Suraneni; W. Jason Weiss The use of superabsorbent polymers (SAPs) in cementitious materials has attracted much attention recently due to the potential benefits associated with internal curing. In this study, a commercially produced SAP is characterized using pore solution...

... replacement powder with internal curing properties. The results show that for a high cementitious mix, where internal curing would be recommended to achieve maximum hydration, up to 10 % replacement with DWTW provides equivalent strength and heat of hydration without negatively impacting setting time. 17...

...Wesley A. Jones; W. Jason Weiss The paper presents results from an experimental investigation on the freezing and thawing behavior of internally cured concrete. Air-entrained internally cured concrete was tested in a series of mixtures. The internally cured concrete was designed where a portion...

...A. E. Miller; T. J. Barrett; A. R. Zander; W. J. Weiss Internally cured (IC) concrete is frequently produced using pre-wetted lightweight aggregate (LWA). One important aspect associated with preparing quality IC concrete is being able to determine the absorbed moisture and surface moisture...

...Michael Golias; Jason Weiss; Dale Bentz Internal curing uses pre-wetted fine lightweight aggregate (LWA) to supply cementitious systems with water. This increases the hydration of cement and reduces the influence of self-desiccation resulting in concrete with increased compressive strength, reduced...
