The concrete mixture is made with a lightweight coarse aggregate. In some cases a portion or the entire fine aggregate may be a lightweight product. Lightweight aggregates used in structural lightweight concrete are typically expanded shale, clay or slate materials that have been fired in a rotary kiln to develop a porous structure.
Norlite is a manufactured lightweight, porous ceramic material produced by expanding and vitrifying select shale in a rotary kiln. The process produces a consistent and predictable high quality ceramic aggregate that is structurally strong, physically stable, durable, .
According to Riley, the chemical composition of the bloating raw materials used to obtain the lightweight aggregates should meet the following requirements: SiO 2 48–70%, Al 2 O 3 8–25%, Fe 2 O 3 + FeO 3–12%, CaO + MgO 1–12%, and K 2 O + Na 2 O –7% (Riley, 1951).This desirable composition covers the required conditions for the bloating process by forming the glassy phase with ...

lightweight aggregates, including pumice, expanded shale and bottom ash. The characteristics of these lightweight aggregates are correlated with thermal conductivity and resistance of concrete slabs made with the lightweight aggregates. Versaliteª is a manufactured lightweight aggregate, which is currently produced from spray dryer ash
Most lightweight aggregate is produced from materials such as clay, shale, or slate. Blast furnace slag, natural pumice, vermiculite, and perlite can be used as substitutes, however. To produce lightweight aggregate, the raw material (excluding pumice) is expanded to about twice the original volume of the raw material.
The clay clasts or particles in shale are less than millimeters in diameter, which means the structure of the rock only becomes visible under magnification. The clay comes from decomposition of consists of at least 30 percent clay, with varying amounts of quartz, feldspar, carbonates, iron oxides, and organic shale or bituminous also contains kerogen, a mixture ...
The Expanded Shale, Clay and Slate Institute (ESCSI) had experience that seemed to indicate this wasn''t true so they teamed up with Peter Craig for some research. The team performed a 13month study comparing normal weight concrete to lightweight in an unconditioned space in Dalton, Ga., with both burnished and unburnished floor finishes.
4) Lightweight chert CHEMICAL PROPERTIES The chemical properties of aggregates ha ve to do with the molecular structure of the minerals in the aggregate particles. COMPOSITION The chemical composition of aggregate is significant in determining the difference between limestone and dolomite. Limestone is a rock consisting

Expanded Shale, Clay and Slate is the Lightweight Aggregate of Choice for Adhered Manufactured Stone Masonry Veneer Stone veneer has been used in construction since the Roman Empire. Today, Adhered Manufactured Stone Masonry Veneer is a lightweight concrete manufactured synthetic stone made to resemble natural stone in size, shape and texture. The
Manufacturing of lightweight aggregates (6) Manufactured lightweight aggregates are produced by expanding some raw materials in a rotary kiln, on a sintering grate, or by mixing them with water. The most common lightweight aggregates are pumice, scoria, expanded shale, expanded clay, expanded slate, expanded perlite, expanded slag and

Two general types of lightweight aggregates are covered by this specification: aggregates prepared by expanding, pelletizing, or sintering products such as blastfurnace slag, clay, diatomite, fly ash, shale, or slate; and aggregates prepared by processing natural materials, such as pumice, scoria, or tuff.
aggregates refers to an aggregate that is lightened in weight by sintering expanded shale, clay, slate, and/or coal fly ash [1–3]. Recently, the production of lightweight aggregates using various types of waste has been studied [4–8]. The development of lightweight aggregates using waste materials is extremely promis
