Differences in manufacture can account for variations in the absorbed moisture equilibrium of samples of lite same cellular concrete. But experiments at the Lithuanian Research Institute of Building and Design hare shown that the absorption capacity of cellular concretes, and thus the moisture content of the associated building envelopes, are greatly ...

Evaluation of concrete cover depth for green concretes exposed to carbonation
Structural Concrete, 2020AbstractCarbonation resistance of fly ash concrete (FAC) and recycled aggregate concrete (RAC) has been extensively tested in the past decade, but there are still no recommendations for their application in codes of practice. Therefore, the main objective of this study was to determine the minimum concrete cover depth of RAC and FAC exposed to ...

Carbonate concretions—explained
Geology Today, 2013Carbonate concretions are common features of sedimentary rocks of all geological ages. They are most obvious in sandstones and mudstones as ovoid bodies of rock that protrude from natural outcrops: clearly harder or better cemented than their host rocks. Many people are excited by finding fossils in the centre of mudstone‐hosted concretions (Fig.

Researches on Concrete Carbonation
Applied Mechanics and Materials, 2013The cause and prevention of concrete carbonation are core issues in the engineering community. With the improvement of the global CO2 concentration, more and more reinforced concrete buildings are faced with the problems of carbonation acceleration and following threats of steel corrosion which will heavily undermine the safety and durability of R.C ...

Cathodic Protection of Reinforcement in Carbonated Concrete
CORROSION 1998, 1998Abstract The protection mechanism of cathodic protection applied to carbonated concrete structures have been investigated. Tests were carried out on reinforced concrete specimens with alkaline concrete, carbonated concrete and carbonated concrete with 0.4% chloride by cement weight.

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.

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,
