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 […]

Concrete Durability Improvement in a Sulfate Environment

To do so, seven groups of 70-mm concrete prisms were made using two different bacterial strains accompanied with mixing water; the effects of sulfate solution exposure on durability properties of tested specimens including mass variation, volume variation, water absorption, and compressive strength were then determined.

Water Permeability Characteristics of Normal Strength

Water permeability characteristic of concrete made from crushed clay bricks as coarse aggregate is investigated and compared with concrete made from natural stone aggregate. For this, six different brick and five different natural stone samples were selected. Crushing strength of brick samples and water absorption of aggregate produced from them were also measured. Concrete samples of three different compressive strengths were prepared as per ACI mix design method from each of these aggregate sa
