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

Carbonation and distressed concrete
Structural Survey, 1990Discusses the properties of concrete and the process of carbonation which can lead to corrosion and its ultimate destruction. Outlines the conditions which lead to carbonation, detailing design faults which facilitate the process, and suggests preventatives which can protect the surface.

Mechanical properties of carbonated concrete
Journal of the Chinese Institute of Engineers, 2003Abstract In this paper, mechanical properties of carbonated concrete were studied. Com‐pressive strength, splitting tensile strength, elastic modulus, bond strength and hardness for carbonated concrete subjected to various carbonation conditions were evaluated.

Concrete carbonation in arid climate
Materials and Structures, 2002Fifty-four different concrete mixes were exposed to hot arid weather in Kuwait to monitor their extent of carbonation. Various parameters affecting carbonation such as water/cement ratio, cement content, type of cement, type and dosage of admixture, water-curing period, type of coating, and the addition of silica fume or pulverized fuel ash were ...

Carbon Sequestration In Concrete
2016Concern for the environmental impact of increased carbon dioxide in the atmosphere has focused attention on reducing emissions of both natural and industrial carbon dioxide. This thesis explores a method for inhibiting or preventing the oxidation of carbon in plant material by encapsulating biomass in a mortar composed of portland cement, natural sand,

Carbon resistance of corundum concretes
Refractories, 1988The resistance of the corundum concretes to carbon during direct interaction under the conditions of high temperature isothermal holding is quite high. After holding for a period of 120 h at 1580°C, the weight loss of the concrete specimens is insignificant (0.2–0.4%) without exception.

Lower-carbon concrete technologies
The Structural EngineerIn this article, we introduce the IStructE's new concrete technology tracker, which has been compiled to inform members about the development of lower-carbon alternatives to conventional Portland cement-based concrete. We also look in more detail at four emerging technologies: Limestone Calcined Clay Cement, Seratech, Cambridge Electric Cement, and ...

Concrete with Accelerated Naturally Carbonated Recycled Concrete Aggregates
Journal of Materials and Polymer ScienceRecycled concrete tends to be increasingly investigated with respect to the environmental needs, such as resource depletion, circularity and lack of landfill disposal spaces. A naturally accelerated carbonation procedure by using atmospheric CO2 concentration level and a cyclic wetting and drying of the recycled concrete aggregates was applied.
