Enhancing Mechanical Strength of Inorganic Geopolymer by Using Phenol Resin

The effect of organic phenol on the compressive and flexural strength of a metakaolin based geopolymer is studied. It was found that 12 wt% phenol resins can increase the compressive and flexural strength by 30% and 65% respectively. In addition, the reinforcing effect of phenol resin is higher in Na-PS and Na-PSS type geopolymers rather than Na-PSDS. Two distinct endothermic peaks were detecte...

Numerical investigation on the pullout shear strength of soil-nail interface using finite element method

Soil nailing is a popular reinforcement method for stabilizing slopes, excavations, and retaining walls in many countries. The pullout capacity of the soil-nail interface is a critical parameter for the design and safety assessment of soil-nailed systems. In this paper, a three-dimensional (3D) finite element (FE) model is developed using the commercial program ABAQUS to simulate the pullout te...

Strength and Interface Analysis

fiber post (GFP) treated or not with phosphoric acid, silane coupling agent, and unfilled resin. GFPs were etched or not with 37% phosphoric acid and different surface coating applied: silane coupling agent, unfilled resin, or both. Composite resin blocks were built around a 4-mm height on the GFP. Unfilled resin (20 s) and composite resin (40 s) were light activated by a light-emitting diode u...

Enhancing usability using automated security interface adaptation (ASIA)

This paper investigates users’ understanding of security features and application and examinesperceptions relating to usability. The study made use of an online survey consisting of fivesections and recruited a total of 564 participants. Respondents were presented with a range ofquestions designed to measure their experience and knowledge of security. In addition, 2scenarios wer...
