L-Shaped Steel Collars: An Alternative External Confining Retrofit for Improving Ductility and Strength of Rectangular Concrete Columns [PDF]

Confinement in concrete column has been well known to improve its strength and ductility. Such enhancement is primarily essential when needed to improve the behavior of concrete columns particularly in terms of ductility during the earthquake strike ...

Improving the performance of concrete using 3D fibres

, 2012
This paper examines whether 3D fibre reinforcement can improve the toughness and flexural strength of concrete, when compared to equal dosage of straight steel fibres. This work was carried out to determine structural qualities that may lead to potential

Influence of section depth on the structural behaviour of reinforced concrete continuous deep beams

, 2007
YesAlthough the depth of reinforced concrete deep beams is much higher than that of slender beams, extensive existing tests on deep beams have focused on simply supported beams with a scaled depth below 600 mm.

Experimental study on mechanical properties of basalt fiber reinforced nano-SiO2 concrete after high temperature

Frontiers in Materials
In enhancing the high-temperature resistance of concrete, incorporating fiber materials was established as an effective approach. This study focused on evaluating the cubic compressive strength, splitting tensile strength, prism compressive strength, and

Evaluation of Fly Ash in Water Reduced Paving Mixtures;MLR-84-07, June 1985 [PDF]

, 1985
Fly ash was used to replace 15% of the cement in C3WR and C6WR concrete paving mixes containing ASTM C494 Type A water reducin9 admixtures. Two Class C ashes and one Class F ash from Iowa approved sources were examined in each mix.
