The objective of this research was to improve the bearing capacity soil located on Kampung Juhut Street, Pandeglang Regency, which initially had a 3.01%, through stabilization methods. plastic powder selected as an additive due its non-cohesive characteristics, counterbalance cohesive nature clay soil. study aimed identify type and classification, evaluate impact physical properties, examine ch...

objectives: maintaining pulp vitality is a main goal in restorative dentistry. introduction of pulp capping agents paved the way to eliminate the shortcomings of these materials and obtain successful restorations. on the other hand, nanotechnology is an emerging field of science with increasing use in dental materials. this study sought to assess the effect of addition of nano-tio2, nano-sio2 a...

An experimental technique is developed to impose a planar lateral confinement in a prismatic specimen (with rectangular cross-section); the setup enabled a controlled and homogeneous stress state with high lateral compressive stresses. A transparent polycrystalline aluminum oxynitride (AlON) specimen was used for the study. The statically pre-compressed specimen was then subjected to axial dyna...

This paper explores a set of new equations to predict the bond strength between fiber reinforced polymer (FRP) rebar and concrete. The proposed equations are based on a comprehensive statistical analysis and existing experimental results in the literature. Namely, the most effective parameters on bond behavior of FRP concrete were first identified by applying a factorial analysis on a part of t...

The predictability of masonry arch bridges and their behaviour is widely considered doubtful due to the lack of knowledge about the conditions of a given masonry arch bridge. The assessment methods for masonry arch bridges are MEXE, ARCHIE, RING and Frame Analysis Method. The material properties of the masonry and fill material are extremely difficult to determine accurately. Consequently, it i...

This study reports the synthesis and evaluation of a novel furanone-containing antibacterial resin composite. Compressive strength (CS) and S. mutans viability were used to evaluate the mechanical strength and antibacterial activity of the composites. With 5% to 30% addition of the furanone derivative, the composite showed no change in CS but a significant antibacterial activity with a 16% 68% ...

Freezing-thawing resistance is a very significant characteristic for concrete in severe environment (such as cold region with the lowest temperature below 0°C). In this study, ordinary-air-entrained (O-A-E) concrete was produced in a laboratory environment; the compressive strength, cubic compressive strength of C50, C40, C30, C25, and C20 ordinary-air-entrained concrete, tensile strength, and ...

Granite is a typical crystalline material, often used as a building material, but also a candidate host rock for the repository of high-level radioactive waste. The petrographic texture-including mineral constituents, grain shape, size, and distribution-controls the fracture initiation, propagation, and coalescence within granitic rocks. In this paper, experimental laboratory tests and numerica...
