Bonding and Strength of Aggregate01:12

Bonding and Strength of Aggregate

482
The bond between aggregate particles and the cement matrix is significantly influenced by the shape and surface texture of the aggregates. High-strength concretes benefit from a rougher texture, which leads to stronger bonding due to greater adhesion. Angular aggregates with larger surface areas also enhance this bond. The bonding quality, however, is complex to assess as no universally accepted test exists. Good bonding is indicated when a crushed concrete specimen shows some aggregate...

Bond Energies and Bond Lengths

31.3K
Stable molecules exist because covalent bonds hold the atoms together. The strength of a covalent bond is measured by the energy required to break it, that is, the energy necessary to separate the bonded atoms. Separating any pair of bonded atoms requires energy — the stronger a bond, the greater the energy required to break it.

Ionic Bonds

Overview
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.

Binary Acids and Bases
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...

Peptide Bonds02:43

Peptide Bonds

82.5K
A peptide bond covalently attaches amino acids through a dehydration reaction. One amino acid's carboxyl group and another amino acid's amino group combine, releasing a water molecule. The resulting bond is the peptide bond. The products that such linkages form are peptides. As more amino acids join this growing chain, the resulting chain is a polypeptide. Each polypeptide has a free amino group at one end. This end has the N-terminal, or the amino-terminal, and the other end has a free...

Covalent Bonding and Lewis Structures

Compared to ionic bonds, which results from the transfer of electrons between metallic and nonmetallic atoms, covalent bonds result from the mutual attraction of atoms for a “shared” pair of electrons.

Area of Science:

  • Dental Materials Science
  • Biomaterials Engineering
  • Ceramic Research

Background:

  • Aesthetic translucent zirconia is increasingly used in dental restorations.
  • Understanding the long-term bond strength of different zirconia compositions is critical for clinical success.
  • Aging effects on material properties require thorough investigation.

Purpose of the Study:

  • To compare the bond strength of two aesthetic translucent zirconia compositions.
  • To evaluate the influence of aging on the bond strength of these materials.
  • To assess fracture types and analyze material performance under simulated aging conditions.

Main Methods:

  • Specimens of ICE Zirkon TZ and Prettau Anterior zirconia (PAZ) were prepared.
  • Samples were aged in distilled water at 37°C for 24 hours (T1) and 90 days (T2).
  • Microshear bond strength, fracture type, and scanning electron microscopy were used for evaluation.

Main Results:

  • Statistically significant differences in bond strength were observed between the ceramic types and aging times (p < 0.01).
  • Prettau Anterior zirconia (PAZ) demonstrated significantly higher bond strength than ICE Zirkon TZ at both aging periods.
  • Aging significantly impacted the bond strength of both zirconia types.

Conclusions:

  • Prettau Anterior zirconia (PAZ) exhibits superior bond strength compared to ICE Zirkon TZ.
  • The findings suggest PAZ is a more durable material for long-term dental applications.
  • Aging negatively affects the bond strength of translucent zirconia, with varying degrees based on composition.
