Due to the high water absorption capacity, the expanded shale lightweight aggregates were pre-soaked for a minimum of 72 h. The saturated surface dry expanded shale aggregates were mixed for 5 min with 75 % of the mixing water then added to the cementitious materials and mixed for an additional minute. Finally, the remaining water …

We judiciously select raw materials that possess unique physical characteristics to produce our high performance, rotary kiln expanded shale aggregates. The extreme heat makes our unique shale raw material expand and bloat creating a new ceramic product that is both stronger than common shale and 30% lighter by volume.

to produce expanded shale, clay, and slate. LWAs are manu-factured by heating small particles of shale, clay, or slate in a rotary kiln. A particle size was discovered that, with limited crushing, produced an aggregate grading suitable for making lightweight concrete (Expanded Shale, Clay and Slate Insti-tute 1971).

Arcosa Lightweight is the largest producer of rotary kiln expanded shale and clay lightweight aggregate in North America, with production facilities in Alabama, Arkansas, …

Before heating the samples, the materials' usefulness for producing lightweight aggregates was examined by detecting the elemental and mineralogical composition of the shale samples. The presence of aluminosilicates and flux content confirmed and met the required conditions discussed by Riley's theory for the bloating …

Expanded shale is used by orchid and bonsai enthusiasts to create lightweight, aerating, water retentive potting soils. It can be used with other containerized plants as well. Put a third of the shale in the bottom of the pot and then mix the shale with potting soil 50-50 for the rest of the container. To lighten heavy clay soil, lay a 3-inch ...

3.1.12 Lightweight expanded clay aggregate (LECA) LECA [80,98,112–114] is a cellular material produced exploiting the clay expansion processes at high temperatures. The granular material can be used loose or mixed with plaster. It is also used to produce lightweight concrete [115]. The thermal conductivity of these materials …

Abstract. In recent years lightweight aggregates are being used increasingly in geotechnical applications. This paper presents results of large-size one-dimensional compression and direct shear tests performed on lightweight aggregate. The compressibility and shear strength characteristics of the lightweight aggregate are …

TruGro Expanded Shale. TruGro® is a lightweight aggregate produced from raw shale. Fired in a rotary kiln at over 2,000 degrees Fahrenheit and then rapidly cooled, it transforms into a porous, lightweight, chemically inert and hard material useful for many applications. Expanded shale is approximately half the weight of sand and gravel, which ...

Arcosa Lightweight is the largest producer of rotary kiln expanded shale and clay lightweight aggregate in North America, and is uniquely situated to supply expanded shale and clay lightweight aggregate to markets in …

In this paper, for a wide application of high-performance steel fiber reinforced expanded-shale lightweight concrete (SFRELC) in structures, the shear behavior of reinforced SFRELC beams without web reinforcements was experimentally investigated under a four-point bending test. Twenty-six beams were fabricated …

Structural lightweight concrete (SLC) made from expanded shale, clay or slate (ESCS) aggregate not only provides several benefits to make foundations more durable, but it also alleviates concerns ...

These expanded materials make it possible to reduce weight without sacing strength. This is accomplished by using only slightly richer mixes than would be required to obtain …

Committed to manufacturing the finest quality, high strength, low absorption lightweight aggregate in the world. As a part of this commitment to quality, we procure the highest grade raw material, utilize current testing and manufacturing technologies, employ the most knowledgeable and experienced people, and constantly research new approaches that …

This paper presents the development of lightweight self-consolidating concrete (LWSCC) using three types of lightweight aggregates, namely furnace slag, expanded clay, and expanded shale.

rticle sizes ensures a high interstitial void content that approaches 50% in the loose state. North American rotary kiln plants producing expanded shales, clays, and slates currently supply coarse [and fine] aggregates to ready-mix and precast concrete manufacturers with 20 to 5 mm (3/4 -#4), 1. to 5 mm (1/2 -#4), or 10 to 2 mm (3/8 -#8 ...
