Deicing Concrete Pavement Containing Carbon Black/Carbon Fiber Conductive Lightweight Concrete Composites

ICTIS 2011, 2011
The electrical and mechanical performance of carbon fiber (CF)/carbon black (CB) lightweight concrete (LWC) depends on CF content, preparation method and sand ratio. As CB content is 0.83 vol.%, CF content is more than 0.49 vol.%, and resistivity of CF/CB LWC is less than 102 Ω·cm, Compressive strength and flexural strength reach more than 30 MPa and 5

Fibre optic strain sensor for carbon concrete composites

2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017
The work introduces textile based carbon structures that are functionalized with optical fibre sensors for structural health monitoring (SHM) of concrete based composites. The concept of the functionalized carbon reinforcement structure is shown in Fig. 1a. The optical fibre (that contains the sensors) is integrated directly during the manufacturing of

Using carbon fiber composites for reinforcing pervious concrete

Construction and Building Materials, 2016
Abstract Pervious concrete (PC) pavement applications are growing in popularity due to the environmental and stormwater management benefits that PC can offer. However, relatively low mechanical properties and durability of PC, comparing to conventional Portland cement concrete (PCC), limit its use for vehicular applications.

Behavior of concrete columns confined by carbon composite tubes

Canadian Journal of Civil Engineering, 2004
The carbon composite tube can play an important role in replacing or complementing longitudinal and transverse reinforcing steels by providing ductility and strength for conventional columns. In this study, both experimental and analytical investigations of axial behavior of large-scale circular and square concrete columns confined by carbon composite

Towards Standardization: Testing and Design of Carbon Concrete Composites

2017
The standardization of testing methods and design approaches is one key to overcome barriers which interfere radical innovation in the AEC (Architectural, Engineering and Construction) industry. Currently, the radical innovative Carbon Concrete Composite, including textile reinforced concrete (TRC), embraces a widespread set of testing methods ...

Strengthening of Reinforced Concrete Beams by Carbon Fiber Composites

Materials Science Forum, 2018
The paper considers the results of the experimental study of the reinforced concrete beams strengthened by carbon fiber reinforced plastics (the CFRP). Eight reinforced concrete beams of the 80x160 mm section and 1500 mm designed span have been manufactured and tested.

Oxygen and carbon isotopic composition of marine carbonate concretions; an overview; discussion and reply

Journal of Sedimentary Research, 1993
In their review of isotopic data from marine carbonate concretions, Mozley and Burns (1993, p. 8 i) incorrectly associate our work (Dix and Mullins 1987) with their interpretation of the effects of recrystallization on isotopic compositions in concretions. Mozley and Burns (1993, p.

Carbon and Oxygen Isotopic Compositions of Carbonate Concretions of the Talchir Formation and their Palaeoenvironmental Implications

Journal of the Geological Society of India, 2002
Abstract: Ubiquitous presence of carbonate rich nodules in glaciogene sediments of various Permo-Carboniferous basins (Talchir) in peninsular India offers promise for delineating the climatic condition and environment of deposition at that time.

Cement Composites with Carbon‐Based Nanomaterials for 3D Concrete Printing Applications – A Review

The Chemical Record, 2023
Abstract3D concrete printing (3DCP) is an emerging additive manufacturing technology in the construction industry. Its challenges lie in the development of high‐performance printable materials and printing processes. Recently developed carbon‐based nanomaterials (CBNs) such as graphene, graphene oxide, graphene nanoplatelets, and carbon nanotubes, have
