... ABSTRACT Nowadays, heavy metal pollution in seabed silt is becoming more and more serious. In this study, a new disposal method of using dredged sludge mud mixed with quicklime, sand and cement to produce bricks was proposed. Taking the water absorption and compressive strength of unburned...

... by the chloride ion ingress and subsequent spalling due to volume expansion of steel rust. Besides, a damaged surface is prone to water absorption and loss of effective buoyancy in the case of floating structures. This paper presents two chloride resistance tests and a long-term water absorption test on LWACs...

... ABSTRACT The authors have developed a new lightweight coarse aggregate whose surface is covered by a high molecular paraffin to prevent water absorption into the aggregate under high pumping pressure. The coated aggregate makes it possible to produce lightweight concrete with high durability...
