Improving the fluid transport properties of heat-cured concrete by internal curing
Construction and Building Materials, 2018Abstract Heat curing accelerates cement hydration, leading to a coarse pore structure. This undermines the transport properties of concrete, which is essential in evaluating concrete durability. In this study, effect of saturated lightweight fine aggregate (LWFA) on the mechanical and transport properties and the microscopical characteristics of heat-

Reducing Curing Requirements for Pervious Concrete with a Superabsorbent Polymer for Internal Curing
Transportation Research Record: Journal of the Transportation Research Board, 2012This paper presents the results of a research project to investigate reducing the need for curing pervious concrete under plastic by incorporating a superabsorbent polymer (SAP) normally intended for internal curing. Pervious concrete samples were produced with and without the SAP along with additional curing water.

Internal curing – A suitable method for improving the performance of heat-cured concrete
Construction and Building Materials, 2016Abstract Heat curing decreases the maximum achievable degree of hydration, long-term rate of increase of compressive strength, anti-permeability, and durability of concrete as it ages. In this study, we explored the suitability of internal curing for solving these problems and improving the performance of heat-cured concrete.

Superabsorbent Polymers for Internally Cured Concrete
2022Two commercial superabsorbent polymer (SAP) formulations were used to internally cure cement pastes, mortars, and concretes with a range of water-to-cement ratios (w/c 0.35–0.52). The following properties were determined as a function of cement chemistry and type, use of chemical admixtures, use of slag, and batching parameters: SAP absorption capacity,

Is international migration a cure for Moroccan unemployment?
The Journal of North African Studies, 2010Recently, much research interest has been directed towards the impact of migration on the sending country. However, we think that this literature does not successfully analyse the effects of migration on unemployment and wage rates, especially in urban areas.

Effect of internal curing on concrete properties
Proceedings of the 3rd International Conference on Engineering and Innovative TechnologyInternal curing has improved the strength and performance of concrete buildings. Insufficient curing of concrete has been shown to result in a considerable loss in its strength, leading to the deterioration of the building's structural performance. This study aimed to investigate the effect of internal curing on concrete properties.

Internal Curing of Concrete Pavements and Overlays
Proceedings of the International Conference on Concrete PavementsInternal curing is an innovative technology to improve the mechanical properties and performance of concrete. The internal water was supplied by fine saturated lightweight aggregate particles (LWA) in this study. The LWA was used to replace a portion of the conventional fine aggregate in the mixture.

Pumice aggregates for internal water curing
International RILEM Symposium on Concrete Science and Engineering: A Tribute to Arnon Bentur, 2004A novel concept in internal curing of High Performance Concrete is based on dispersing very small, saturated lightweight aggregates (LWA) in the concrete, containing sufficient water to counteract self-desiccation. With this approach, the amount of water in the LWA can be minimized, thus economizing on the amount of the LWA.
