The study presented here investigated a low cost calcined shale, sourced from a lightweight aggregate producer, and compared its performance as an SCM to that of a commercially available metakaolin. The effect of both SCMs on compressive strength, resistance to alkali silica reaction and mixture workability were by: 2.

Coating is a layer of substance covering a part or all of the surface of an aggregate particle. The coating may be of natural origin, such as mineral deposits formed in sand and gravel by ground water, or may be artificial, such as dust formed by crushing and handling.

Carolina Stalite Company. Salisbury, NC. 2 2 Structural Lightweight Aggregate LWA is a manufactured aggregate – Raw material is shale, clay or slate – Expanded in a kiln at deg.
F lightweight aggregate is a. Light weight aggregate concrete: Basically two types of light weight aggregates Natural aggregates Artificial aggregates Natural light weight aggregates are less preferred over artificial aggregates.
Important natural aggregates – Pumice & Scoria Artificial aggregates are usually produced by expanding the rocks such as Shale, Slate, Perlite. Lightweight aggregates (LWAs) can be used as aggregates to produce lightweight concretes (LWCs) in a wide range of densities and strengths with different applications.
The low density LWCs with compressive strengths ranging from to MPa are usually employed as insulating by: CLAY OR SHALE DEPOSIT—CERAMIC TEST SAMPLE LOCALITY Low grade—common "brick" clay Intermediate grade—stoneware or refractory clay Clay with no apparent value for ceramic use QUARRY edC N -B/S TCHO s Il 1 R IT O 81 A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the : Chris Neuzil.

Deltac. Two high-performance lightweight concrete (HPLC) mixtures with average compressive strengths of and MPa ( psi) were developed.
Internal Curing Using Expanded Shale, Clay and Slate Lightweight Aggregate The text and references are from ASTM D Significance of Test and Properties of Concrete and Concrete Making Materials, Chapter 46 – “Lightweight Concrete and Aggregate,” American Society of Testing Materials, West Conshohocken, PA Expanded shale can be utilized in structural high strength concrete or as a supportive high strength material with strong insulative qualities in underground applications.
" The Canadian lightweight aggregate supplier " Mix design, strength and deformation test results of lightweight aggregate concrete suitable for structural applications in reinforced and prestressed concrete are presented. It is shown that a wide range of concretes of high strengths and high early strengths can be obtained by suitable mix designs.
CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Common river sand is expensive due to excessive cost of transportation from natural sources.
Also large-scale depletion of these sources creates environmental problems. As environmental transportation and other constraints make the availability and use of river sand less attractive, a substitute or replacement product.

Stout and W. Scott Preliminary Report on Coated Lightweight Concrete Aggregate from Canadian Clays and Shales by H. Wilson Phone: () Many geographical areas and geological formations were missed when the ceramic suitability of materials was studied early this century.
This study provides new data on the ceramic properties of nearly every geological formation in Alberta with ceramic potential and brings together all previously published data in a consistent format.

Sahinkaya and E. Kalıpcı (Editors) Nevsehir, TURKEY, May 20. —Common clays and shales were used to manufacture a wide variety of construction materials, including expanded aggregates, hydraulic cement, and structural clay products. Expanded Clay and Shale.—Approximately Mt of clay and shale was used in the production of lightweight aggregates in compared with Mt in (table 12).
Achieving energy efficiency of building in north part of Kazakhstan is very critical due to the large temperature difference during long harsh and severe winter and short hot summer seasons.
