Cellular Concrete Carbonation

Batiment International, Building Research and Practice, 1985
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 ...

Carbonate concretions—explained

Geology Today, 2013
Carbonate 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.

Biochar-augmented carbon-negative concrete

Chemical Engineering Journal, 2022
Abstract Biochar is a waste-derived carbon-based material that can sequester carbon. This study proposed a revolutionary design of carbon-negative concrete with a large volume of biochar incorporation and elaborated the roles of biochar in the cement hydration and microstructure development of biochar-augmented concrete.

Researches on Concrete Carbonation

Applied Mechanics and Materials, 2013
The 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 ...
