Lightweight concrete can be specified using the notation LC for the strength class, e.g LC30/33, which denotes a lightweight concrete with a cylinder strength of 30MPa and a cube strength of 33MPa. The lighter the concrete, the greater are the differences to be accounted for in the properties of the concrete.

Applications of Lightweight Concrete. Lightweight concrete is used in many different construction projects, including:. Residential buildings: Its better insulation makes it ideal for homes, improving energy efficiency.; Roofing and floors: Due to its lighter weight, it's perfect for flat roofs or floors where traditional normal weight concrete would add too much load.
Keywords: lightweight concrete, lightweight aggregate concrete, infra-lightweight concrete, LC, LAC, ILC, lightweight aggregate, LWA, production, mix design. 1. Introduction. Lightweight concretes are not a modern achievement of concrete technology. They have been known since ancient times and are basically the predecessors of today's concrete.
Lightweight concrete has a history of more than two-thousand years and its technical development is still proceeding. This review starts with a retrospective that gives an idea of the wide range of applications covered by lightweight concrete during the last century. Although lightweight concrete is well known and has proven its technical potential in a wide range of …
Lightweight concrete is defined as having an oven dry density not exceeding 2000 kg/m 3, but can be as low as 800 kg/m 3 depending on the materials used (EN 206:2016). Compressive strength can vary between 1 and 65 N/mm 2. Lightweight concrete has: • Improved thermal properties

Limited investigations have evaluated the potential of using layered sections of normal-weight and lightweight concrete (NWC and LWC) mixtures in structural beams and slabs. The main objective of this paper is to assess the flexural strength properties of layered reinforced concrete (RC) beams, which help conserve natural resources and reduce construction weight. …
Lightweight concrete is primarily used to reduce the weight or load of a concrete structure, thus allowing for smaller sized columns and footings. Manufactured using lightweight aggregates, lightweight concrete can help in the construction of high rises and other buildings that require sturdy and safe flooring. The lightweight aggregates used ...
Lightweight polymer concrete composites have been developed with excellent insulating properties. The composites consist of lightweight aggregates such as expanded perlites, multicellular glass nodules, or hollow alumina silicate microspheres bound together with unsaturated polyester or epoxy resins. These composites, known as insulating ...
lightweight concrete. Lightweight concrete consists of cementitious materials, lightweight coarse aggregate, fine aggregate, admixtures if used, and water. Due to the nature of the aggregates, use of lightweight concrete is more technical than portland cement concrete. Proper planning and quality assurance can reduce problems
Lightweight Roof Pavers were invented to follow the natural slope of the roof and where an existing roof or new roof construction requires a lighter load. Cast with 1" of concrete laminated to a 1 1/2" of expanded polystyrene these pavers have the look and feel of a full weight paver yet weigh in at roughly half the load.

Lightweight concrete is a special type of concrete which weighs lighter than conventional or normal concrete. Density of light weight concrete is conventionally low. Generally 300 kg/m³ to 2200 kg/m³ and thus normal concrete has density between 2200 kg/m³ to …
Lightweight concrete. T.W. Bremner, in Developments in the Formulation and Reinforcement of Concrete, 2008 8.1.1 Terminology. The term " lightweight concrete " which is preferred by the American Concrete Institute (ACI) will be used rather than the more scientifically correct term of lower density concrete (1).The Institute also defines normalweight as one word.
