Accelerated Curing of Concrete

Accelerated Curing of Concrete

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 Concrete

Curing of Concrete

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...

Cationic Chain-Growth Polymerization: Mechanism

Cationic Chain-Growth Polymerization: Mechanism

The cationic polymerization mechanism consists of three steps: initiation, propagation, and termination. In the initiation step of the polymerization process, the π bond of a monomer gets protonated by the Lewis acid catalyst, which is formed from boron trifluoride and water. The protonation of the π bond generates a carbocation stabilized by the electron‐donating group. In the propagation step, the π bond of the second monomer acts as a nucleophile and attacks the generated carbocation,...

Characteristics and Nomenclature of Copolymers

Characteristics and Nomenclature of Copolymers

Copolymers are the products obtained from the polymerization of multiple monomer species. So, in a polymer chain itself, there can be multiple repeating units that come from different monomers. The process of synthesizing a polymer from different monomer species is called copolymerization. When two monomers are involved, the polymer is known as a bipolymer. Polymers with three and four monomers are termed terpolymers and quaterpolymers, respectively. Figure 1 depicts the copolymerization of...

Step-Growth Polymerization: Overview

Step-Growth Polymerization: Overview

Step-growth or condensation polymerization is a stepwise reaction of bi or multifunctional monomers to form long-chain polymers. As all the monomers are reactive, most of the monomers are consumed at the early stages of the reaction to form small chains of reactive oligomers, which then combine to form long polymer chains in the late stages. Hence, the reaction has to proceed for a long time to achieve high molecular weight polymers.
Many natural and synthetic polymers are produced by...

Olefin Metathesis Polymerization: Overview

Olefin Metathesis Polymerization: Overview

Recently, the development of olefin metathesis polymerization advanced the field of polymer synthesis. Simply put, the reorganization of substituents on their double bonds between two olefins in the presence of a catalyst is known as the olefin metathesis reaction. The use of metathesis reaction for polymer synthesis is called olefin metathesis polymerization.
Ruthenium-based Grubbs catalyst is the most commonly used catalyst for olefin metathesis polymerization. Grubbs catalyst consists of a...

Summary

Light-curing (LC) initiation improved dual-cured buildup restorative materials (DCB) conversion compared to self-curing (SC) mechanisms. However, dedicated SC and LC materials generally outperformed DCB, except for LuxaCore DC in LC mode.

Background:

Dual-cured buildup restorative materials (DCB) combine self-curing (SC) and light-curing (LC) properties.
Understanding the curing efficiency of different mechanisms is crucial for material selection and clinical success.

Purpose of the Study:

To compare the curing efficiency of SC and LC mechanisms in DCB materials.
To evaluate the impact of polymerization mode on the conversion of C=C bonds in DCB.

Main Methods:

Four DCB materials were tested: Clearfil DC Core Automix (CD), Cosmecore DC (CM), LuxaCore DC (LX), and MultiCore DC Flow (MC).
Specimens were stored in dark, dry conditions for up to 60 minutes or light-cured immediately.
Remaining C=C bonds (%RDB) were quantified using ATR-FTIR spectroscopy.

Main Results:

Polymerization mode significantly affected DCB efficacy (p<0.0001).
Dedicated SC and LC control materials generally showed higher conversion than DCB materials.
LuxaCore DC (LX) and MultiCore DC Flow (MC) exhibited better SC conversion initially; CM maintained >60% RDB after 60 minutes.

Conclusions:

LC initiation enhanced C=C conversion in DCB compared to their native SC mechanisms.
Dedicated SC and LC materials generally outperformed DCB, with LX in LC mode being an exception.
Clinical performance may vary based on the material's specific curing characteristics.
