Curing Methods01:26

Curing Methods

282
Concrete members with a small surface-to-volume ratio are cured by oiling and moistening the forms before casting the concrete member. These forms can be left in place for a prolonged period to prevent moisture loss, and can be wetted if made of a material suitable for wetting. If the forms are removed early, the concrete member is moistened and covered with polythene sheets to maintain moisture. For large horizontal concrete surfaces exposed to dry weather, a temporary covering is suspended...

Accelerated Curing of Concrete01:25

Accelerated Curing of Concrete

447
Accelerating concrete curing is achieved by applying heat and additional moisture. This process accelerates the hydration of the cement, resulting in an earlier strength gain in the concrete. Steam curing is a method wherein the concrete products are either transported through a chamber on a conveyor belt or encased in plastic, allowing steam at atmospheric pressure to circulate freely around them. This process begins with a phase of moist curing that typically lasts between 3 to 5 hours, after...

Curing of Concrete01:20

Curing of Concrete

351
The hydration of cement takes place within the water-filled capillary pores. However, environmental elements can disrupt this process by evaporating water from the concrete surfaces. Sealed concrete with a water-cement ratio below 0.5 experiences self-desiccation, leading to water loss. The water loss in concrete is mitigated by curing. This technique involves keeping the concrete saturated to maintain the necessary temperature and moisture conditions, to optimally fill the spaces in the cement...

Setting Time of Cement01:12

Setting Time of Cement

591
The setting time of cement refers to the process of cement paste transitioning from a plastic state to a solid state. This process is crucial in construction as it dictates the timeframe for concrete placement, compaction, and finishing. The onset of this solidification is termed the initial set, indicating when the paste becomes unworkable. The final set is when the paste has solidified completely, and further handling or manipulation can no longer affect its shape. The cement strength is...

Retarders01:19

Retarders

257
Retarders are chemical admixtures designed to extend the setting time, which is especially useful when there is a delay in sequential concrete pours to prevent cold joints and to achieve a cohesive structure. Retarders, when used in appropriate amounts, can also enhance the architectural appearance of exposed aggregate finishes.
The function of retarders is to delay the setting of concrete, and this effect can be measured using a penetration test. The retardation process involves adding...

Soundness of Cement01:17

Soundness of Cement

524
The soundness of cement refers to the ability of cement paste to retain its volume after setting. Unsound cement can lead to expansion and structural damage due to the presence of free lime, magnesia, and calcium sulfate. Free lime hydrates very slowly, expanding and causing unsoundness, which is difficult to detect because it intercrystallizes with other compounds. Magnesia also reacts with water, forming crystals that can disrupt the cement's structure. Calcium sulfate can create...

Summary

Light-cured veneer luting agents show reduced curing under ceramic veneers. Using touch-cure activators can improve curing, but instructed tack-curing leads to difficult excess removal.

Area of Science:

  • Dental materials science
  • Biomaterials engineering
  • Restorative dentistry

Background:

  • Light-cured luting agents are crucial for veneer restorations.
  • Light attenuation through ceramic veneers and challenges in excess removal pose clinical issues.

Purpose of the Study:

  • To assess the curing capacity of five light-cured veneer luting agents (VLAs) under lithium disilicate veneers.
  • To evaluate the effect of touch-cure primers and two tack-curing modes (contact and distant) on VLA setting.

Main Methods:

  • Utilized Attenuated Total Reflectance Fourier-Transform Infrared (ATR-FTIR) spectroscopy to measure degree of conversion (DC%).
  • Employed Vickers hardness (VHN) tests to assess material hardness.
  • Tested five VLAs (CH2, GCV, PNV, PMS, VEV) with and without primers under ceramic simulation.

Main Results:

  • All VLAs showed significantly lower DC% under ceramic compared to controls, with VEV and CH2 performing best.
  • Primers improved DC% by 4-13% in veneer groups.
  • Contact tack-curing yielded 37-78% conversion and 31-57% hardness relative to controls, indicating a vitreous state.
  • Distant tack-curing resulted in minimal conversion (0-7% of controls) and untraceable indentations.

Conclusions:

  • Low translucency lithium disilicate veneers significantly reduce VLA curing efficiency.
  • Touch-cure activators can enhance VLA conversion under veneers.
  • Current tack-curing protocols result in vitrified materials, complicating excess removal and highlighting the need for standardization.
