Abstrak. Penelitian ini bertujuan untuk membuat kalsium karbonat terendapkan atau precipitated calcium carbonate (PCC) dari cangkang kerang mutiara melalui pelarutan dengan larutan HNO3, karbonasi dengan karbondioksida, dan sonikasi. Cangkang kerang denga... see more

The clarification of sugar cane juice is a major unit operation in producing white sugar. In Brazil, the traditional method for this process is sulfitation, a technique that uses gaseous SO2 and lime. However, this process has shown some restrictions in i... see more

Carbonation is one of the factors that can influence the chlorides transport. Despite the combined action of chlorides and carbonation being a reality, there is no consensus on the effect of this coupled deterioration on chloride transport. Accelerated te... see more

In this work the technique of impedance spectroscopy electrochemistry (EIS) was used to evaluate the effects of carbon dioxide on the corrosion of ASTM A 706 structural steel embedded in concrete with alkali activated slag (AAS), AAS concrete is a mixture... see more

One of the most important depassivation mechanisms of steel reinforcement in concrete is that caused by the neutralisation of the cement matrix. In this work, a summary of the development of a model for the carbonation of cementitious matrixes (UR-CORE) i... see more

This paper discusses the effects of carbonation on the microstructure of portland cement concrete for longtermdurability applications. A class C40 concrete (characteristic compression strength between 40 MPa and 44 MPaon the 28th  2  th and 91st... see more

The effect of CO2 flow rate and carbonation temperature were studied in the synthesis of PCC from limestone using carbonation method. The synthesis was started by dissolving CaO that was obtained from calcination of limestone into HNO3 6M. The solution wa... see more

The paper presents the results of an investigation conducted to examine carbonation resistance of Self Compacting Concrete (SCC) made with coarse Recycled Concrete Aggregates (RCA). In total, five SCC mixes were prepared by systematically replacing coarse... see more

The paper reviews the studies on one of the important durability properties of concrete i.e. Carbonation. One of the main causes of deterioration of concrete is carbonation, which occurs when carbon dioxide (CO2) penetrates the concrete’s porous system to... see more
