Concrete Exposed to Seawater – Effects and Preventions

Introduction The concrete structures built in marine conditions are always exposed to seawater either directly or indirectly. The coastal and offshore structures are always in contact with seawater and there are number of physical and chemical deterioration processes takes place. So, Concrete structures effected by seawater requires special attention. Composition of Seawater The 71% of []

Types and Causes of Concrete Deterioration

2014. 4. 14. · Concrete and the Passivating Layer Although steel’s natural tendency is to undergo corrosion reactions, the alkaline environment of concrete (pH of 12 to 13) provides steel with corrosion protection. At the high pH, a thin oxide layer forms on the steel and prevents metal atoms from dis-

Batching by volume - DIY - The Concrete Society

Batching by volume - DIY. When concrete is to be mixed on site rather than ordered from a ready-mixed concrete supplier, an estimate of the materials needed is necessary. Materials can be purchased as individual constituents with either the fine and coarse aggregate pre-blended (ballast/all-in aggregate) or separately.The quantities of cement

Evaluation of Relationship between Water Absorption and

Environment has significant effects on the water absorption of concrete materials. This paper presents an experimental study of the influence of water absorption on the durability of concrete materials. A detailed analysis is also presented in order to establish useful relationship between them. Concrete specimens of different water absorption were prepared through different curing conditions, and results indicated that curing condition can significantly affect the surface water absorption. SEM

Performance and Microstructural Analysis of Lightweight

The influence of two lightweight aggregates (LWA) on concrete and the effects of cement substitution for nanosilica (NS) on the interfacial transition zone (ITZ) and cementitious matrix of concrete in resistance to attacks by magnesium sulfate (MgSO 4 ) are researched in this work. The aggregates evaluated were perlite, which is a lightweight aggregate of open porous structure, and expanded
