International Journal of Cement Composites and Lightweight Concrete, 1980
In order to reduce the density of concrete for load bearing and stiffening structural members and to improve the thermal insulation properties and thus extend the scope of application for structural lightweight concrete, closed-texture lightweight concretes are required which, while possessing adequate compressive strength, have densities of less than ...

Lightweight mineral aggregates as discussed herein are those used in the manufacture of portland-cement concrete having a unit weight less than about 120 lb. per cu. ft. Air-cooled blast-furnace slag is excluded, not only because it produces concretes of unit weight greater than about 130 lb. per cu. ft. but also because it is specified and used in the

Journal of Building Engineering, 2017
Abstract Structural lightweight concrete plays an important role in the construction industry, especially for the high-rise buildings. It can only be produced using lightweight aggregates. Oil-palm-boiler clinker (OPBC) is a solid waste from the oil palm industry and could be used as lightweight aggregate in concrete mixture.

Lightweight Aggregates From Incinerated Sludge Ash
Waste Management & Research: The Journal for a Sustainable Circular Economy, 1989A range of artificial aggregates has been developed from incinerated sewage sludge ash. The ash is either pelletized or slabbed and subsequently fired until it sinters and expands to form lightweight products which are later graded for use as aggregates in concrete.

Structural lightweight aggregate concrete offers several benefits as compared to the normal weight concrete. Most common methods of producing structural lightweight concrete is by using artificial lightweight aggregates. However, the cost of the production of artificial lightweight aggregates is high due to energy and raw materials consumption. The use

Surface Modification of Lightweight Aggregate and Properties of the Lightweight Aggregate Concrete
2008Structural lightweight aggregate concrete (LWAC) offers design flexibility and substantial cost savings by providing less dead load [1]. Because of higher water absorption of lightweight aggregate (LWA), process of mixing LWAC is more complex than that of normal weight concrete (NWC).
