  • SYNTHETIC AGGREGATES TECHNOLOGIES Aggregate

    Synthetic aggregates can be produced yearround, stockpiled, used to offset aggregate shortages, and/or be manufactured where mineral aggregates are scarce or for specialized products There are various plant options A producing block plant can be readily modified to produce synthetic aggregate full time, or by just adding a shiftStabilized soils are also being substituted for aggregate in bases and subbases Another approach to the problem is to use synthetic rather than naturally occurring aggregates A study was made to identify existing and potential materials suitable for producing synthetic aggregates, to conceive new methods of producing such aggre­SYNTHETIC AGGREGATES FORTHE SYNTHETIC AGGREGATE MARKET 5th January 2005 THE SYNTHETIC AGGREGATE MARKETBy: David Shulman and Yvonne SmithSynthetic aggregates are recycled materials recombined into a lightweight mineral aggregate substitute No discussion of synthetics is complete without a quick background on the scope of the underlying natural/mineral aggregate marketTHE SYNTHETIC AGGREGATE MARKET • Aggregate

  • Producing synthetic lightweight aggregates from reservoir

    Abstract This paper proposes a procedure to produce lightweight aggregate (LWA) made of fine sediments, which were dredged from the Shihmen Reservoir in the northern Taiwan The synthetic aggregates were manufactured in a newly developed rotary kiln Physical and mechanical properties of the synthesized aggregates were subsequently assessedshown that synthetic aggregates can be developed from compounding coal fly ash and recycled high density polyethylene, HDPE (1,2) One objective here was to develop a new product from two materials currently sent to the disposal facilities The final product, lightweight synthetic aggregate, is a granular material to beSynthetic Lightweight Aggregate Highway ConstructionMiracote Synthetic Aggregate™ Product Technical Data Sheet Miracote Synthetic Aggregate is a single component additive that can be utilized to impart nonskid properties to assorted Miracote sealers It is easily incorporated into MiraGard HD 400, MiraGard HD 100, MiraGard HDWB, MiraThane WB, MiraFlor WB, MiraGard Colorbond XL, or MiraFlorMiracote Synthetic Aggregate™
