Concrete carbonation prediction for varying environmental exposure conditions
… improve the durability performance of reinforced concrete structures. The DI approach is based on durability index tests, which are linked to transport mechanisms related to particular deterioration processes (Alexander et al., 1999a). Carbonation of concrete is governed, inter alia, by the …

Studies of moisture and alkalinity in self-levelling flooring compounds
… are used to level the substrates (mainly concrete slabs) before floor coverings are applied. Although such compounds are used extensively, only limited research on their moisture and alkali properties and their functioning in floor constructions has thus far been conducted. The aim of the …

Carbonated foamed cellular concrete
… bubbles in the paste. The density of cellular concrete usually ranges from 300 kg/m3 to 1800 kg/m3 and has been used for applications such as thermal insulation, dead load reduction, and lightweight fill. Foamed Cellular Concrete (FCC) is one potential material solution to decrease the carbon …

Service life extension of reinforced concrete structures using hydrophobic impregnation
… increasing premature deterioration of reinforced concrete structures, mainly due to rebar corrosion, has become a worldwide concern. This has been attributed to insufficient quality and quantity of cover concrete resulting from inadequate mix design and poor onsite workmanship respectively. …

Modelización del deterioro de tableros de puentes de hormigón por difusión de cloruros y corrosión de la armadura pasiva
… bars is a primary cause in the deterioration of concrete structures, which may be led to failure and even collapse. In any case, the cost of associated repair and maintenance is enormous. Hence, investigations relating to the durability assessment of concrete structures have shown a substantial …

ΜΕΛΕΤΗ ΤΩΝ ΦΥΣΙΚΟΧΗΜΙΚΩΝ ΔΙΕΡΓΑΣΙΩΝ ΕΝΑΝΘΡΑΚΩΣΗΣ ΤΟΥ ΣΚΛΗΡΥΜΕΝΟΥ ΤΣΙΜΕΝΤΟΠΟΛΤΟΥ ΚΑΙ ΤΩΝ ΕΠΙΠΤΩΣΕΩΝ ΣΤΗΝ ΑΝΘΕΚΤΙΚΟΤΗΤΑ ΣΕ ΔΙΑΡΚΕΙΑ ΤΟΥ ΟΠΛΙΣΜΕΝΟΥ ΣΚΥΡΟΔΕΜΑΤΟΣ
STEEL BARS IN REINFORCED CONCRETE ARE PROTECTED FROM CORROSION BY THE HIGH PH ENVIRONMENT OF THE SURRONDING CONCRETE. THIS ALKALINE ENVIRONMENT IS DESTROYED BY THE GRADUAL DIFFUSION OF ATMOSPHERIC CO2 INTO THE CONCRETE PORES, AND ITS REACTION WITH THE CA(OH)2 OF THE CONCRETE MASS. WHEN THIS …

Carbonation of Functionally Graded Concrete
In this thesis, the carbonation of functionally graded concrete is investigated through a combination of experimental and analytical approaches. The properties of functionally graded concrete vary throughout the cross-section to satisfy performance requirements in a resource-efficient manner. In …
