Comparative Study About Mechanical Properties of Strutural Standard Concrete and Concrete with Addition of Vegetable Fibers [PDF]

open access: yesMaterials Research, 2017
This paper explored the effect of adding organic fibers from either bamboo or sugarcane on the mechanical properties of concrete. Cylindrical and prismatic specimens were made containing 2% and 5% v/w (volume to weight) of vegetable fibers to concrete.

Assessment of Printability of Concrete based on Packing of Aggregates [PDF]

open access: yes
The fluidity of concrete is a key parameter that determines the printability of the mixture in an extrusion-based printing process. The printability of concrete is influenced by the relative proportions of aggregate and paste, paste rheology and the ...

Advancements in sustainability of 3D concrete printing: Presenting low-carbon mixtures for additively manufactured concrete structures in practice [PDF]

open access: yes
3D concrete printing (3DCP) is regarded as an environmentally friendly construction technique with minimum waste generation. However, challenges persist, particularly in the composition of 3D printable concrete mixtures. The need for specific rheological

Enhancing Sustainable Concrete Properties by Green Vegetable Substance

open access: yesInternational Journal of Engineering and Technology, 2018
From several points of view, disposal of waste materials in an environment is respected to be a significant problem because of its very low biodegradability and existence in huge quantities. Waste of plastic and metal bottles caps, cans of juices and soft drink, and tires rubber being among the most pronounced.

The role of vegetation science in the conservation of cultural landscapes [PDF]

open access: yes, 2023
Cultural landscapes are defined as the results of the combined action of nature and humans on the territory. Millennia of human presence on most of the Earth resulted in the current existence of many different cultural landscapes, shaped by different ...

Measures to improve the Strength Development of Low Carbon Sprayed Concrete

open access: yes
A characteristic feature of sprayed concrete is the fast setting and hardening. This is typically achieved through a high content of Portland Cement clinker in the concrete in combination with a liquid alkali-free accelerator, which is added at the ...

Rheological Modifiers in Optimizing Quick Nozzle Mixing Technology for 3D Concrete Printing [PDF]

open access: yes
Quickly mixing concrete at or near the printing nozzle is a new technique developed by the authors to improve 3D concrete printing technology. Quick nozzle mixing (QNM) solves the inherent problem in 3D concrete printing due to the opposing rheological ...

Nonlinear finite element of FRP reinforced concrete structures.

open access: yes, 2012
reinforcement is a non-corrosive alternative to steel and is gaining popularity for use in reinforced concrete structures exposed to corrosive environments. A major difference between the two reinforcing materials is their behaviour at failure.
