[Shear bond test of HF acid etching machinable porcelain bonded to enamel with different concentration and disposing
Abstract:
After HF acid etching under 5 different HF concentrations and 6 exposing times, shear bonding strength of porcelain to enamel were tested. The results showed that HF acid etching technique had a positive influence on the bonding strength of porcelain to enamel. The most favorable concentration-time groups were 2.5%-5.0 min, 5.0%-5.0 min, 7.5%-2.5 min, 10.0%-1.0 min, 15.0%-0.5 min, and the debonding type of porcelain-resin-enamel composite body was mixed debonding.

Testing Water Quality
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
Bonding and Strength of Aggregate
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...
