The lightweight aggregate can be natural aggregate such as pumice, scoria and all of those of volcanic origin and the artificial aggregate such as expanded blast-furnace slag, vermiculite and clinker aggregate. The main characteristic of this lightweight aggregate is its high porosity which results in
01-07-1995· Structural lightweight concrete also resists fire better than normalweight concrete because of its lower thermal conductivity and its lower coefficient of thermal expansion. In many structures, these benefits justify the use of lightweight aggregate concrete, which generally costs more than normalweight concrete.

One way is to incorporate a lightweight aggregate. Natural lightweight aggregates such as pumice [most widely used], scoria, volcanic cinders, tuff and diatomite. Or artificial aggregates or rotary kiln produced lightweight aggregates such as expanded clays, slates, slag, perlite or shale's. Cenospheres
lightweight aggregate, there will be essentially no increase in strength. Figure 7.1 demonstrates that the compressive strength ceiling for the particular 3/4 in. (20.0-mm) maximum size lightweight aggregate tested was about 8,000 psi (55 MPa) at a concrete age of
Experimental Study of Light Weight Concrete by Partial Replacement of Coarse Aggregate Using Pumice Aggregate CASE STUDY14 Coarse Aggregate Crushed stone coarse aggregate conforming to IS 383 – 1987. The values of loose and compacted, bulk density values of coarse aggregates 4.417 kg and 4.905kg, Cement Ordinary Portland Cement (53 Grade) with 29%. normal consistency
The basic design for lightweight concrete is covered in Eurocode 2 Part 1-1, with section 11 having particular rules required for lightweight aggregate concretes. Concrete is considered to be lightweight is the density is not more than 2200kg/m 3 (the density of normal weight concrete is assumed to be between 2300kg/m 3 and 2400kg/m 3 ) and a proportion of the aggregate should have a density
Unfortunately the article above confuses lightweight aggregate concrete for aerated autoclaved concrete (AAC). AAC is not used to precast structures nor is it moisture cured using pre-wetted lightweight aggregates. It is fully cure-hardened in high-pressure autoclaves for about 12 hours in the form of blocks and structural panels.
Lightweight aggregate concrete is prepared by using lightweight aggregate or low density aggregate such as volcanic pumice, clay, slate, shale, scoria, tuff and pellite. Concrete is considered to be lightweight is the density is not more than 2200 kg/m3, when compared to normal concrete which is 2300-2400 kg/m3 and a proportion of the aggregate, should []
Our lightweight aggregates from Lytag® are made from fly ash generated by coal fired power stations. Our technology heats the fly ash to 1,100°C to create a hard pellet, with a honeycombed internal structure. Which can then be used as a superior, lightweight aggregate which is up to 50% lighter than natural aggregate.
Lightweight aggregate(sometimes is called as low density aggregate) is a generic name of a group of aggregates for structural concrete, mortar, or plaster that weighs

Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³).

Lightweight aggregate is a type of coarse aggregate that is used in the production of lightweight concrete products such as concrete block, structural concrete, and pavement. The Standard Industrial Classification (SIC) code for lightweight aggregate manufacturing is 3295; there currently is no Source Classification Code (SCC) for the industry.
LABORATORY INVESTIGATION OF LIGHTWEIGHT CONCRETE PROPERTIES H. Celik Ozyildirim, Ph.D., P.E. Principal Research Scientist INTRODUCTION Lightweight concrete (LWC) has been used for more than 2,000 years (ACI 213R) (American Concrete Institute [ACI], 2003). Early notable LWC structures include the Port of Cosa, the Pantheon Dome, and the Coliseum.
The basic design for lightweight concrete is covered in Eurocode 2 Part 1-1, with section 11 having particular rules required for lightweight aggregate concretes. Concrete is considered to be lightweight is the density is not more than 2200kg/m 3 (the density of normal weight concrete is assumed to be between 2300kg/m 3 and 2400kg/m 3 ) and a proportion of the aggregate should have a density
With Poraver®, special concretes are lightweight, cold- and moisture-resistant and durable. In particular, the combination of low bulk density and high strength makes Poraver® a suitable lightweight aggregate for exposed concrete, fiber-reinforced concrete as well as laminate and textile concrete.
