Mechanical Behavior of Concrete Modified by Replacement of Cement by Rice Husk Ash
Construction industry is in need of lump sum quantities of materials which has increased both their demand and price. The use of large quantities of cement leads to increasing CO2 emission and as a consequence, the greenhouse effect.

Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.

A New Approach for Determining the Curvature Ductility of Reinforced Concrete Beams
This paper presents a numerical parametric study of the moment-curvature and curvature ductility of doubly-reinforced beams with different parameters. The effects of the strength of the concrete and the amount of the reinforcement, including the tensile ...

Effect of vertical circular openings on flexural strength of reinforced concrete beam
Modern building construction techniques sometimes involve the passing of pipes or ducts for water supply, electrification, and telecommunication through reinforced concrete beams to protect them against mechanical damages and add aesthetic value to ...

Temperature-dependent resistivity of suspended graphene
In this paper we investigate the electron-phonon contribution to the resistivity of suspended single layer graphene. In-plane as well as flexural phonons are addressed in different temperature regimes.
