Slag Aggregate - an overview ScienceDirect Topics

A synthetic aggregate may also be the byproduct of manufacturing and a final burning process—blast furnace slag is an example of a synthetic aggregate. Briefly, blast furnace slag is formed when iron ore or iron pellets, coke, and a flux (such as limestone, CaCO 3, or dolomite, CaCO 3 MgCO 3) are melted together in a blast furnace. When the ...

differences in concrete properties using 10mm to 20mm ...

When you use a smaller aggregate, such as the 10mm as your nominal coarse aggregate size, the specific surface area of the total volume of coarse aggregate is much higher than for the 20mm aggregate. This means that your mix will require more cement, more water and more fine aggregate in order to provide adequate paste coverage of the coarse ...

Concrete Aggregates Boral

Coarse Aggregate is normally greater than 5mm. Fine Aggregate is aggregate less than 5mm. Can be a single sized material typically 20mm, 14mm, 10mm,or 7mm or a graded aggregate consisting of a blend of single sized aggregate. Concrete Aggregates are produced to Australian Standards (AS 2758) or to more specific customer requirements.

Your question is not clear. Do you want to use concrete with nominal maximum size of aggregate less than 20 mm (i.e. 10 mm, 12.5 mm or 6.3 mm) or you wish to have concrete with say NMSA 40 mm and jumping to 10 mm while grading. Scenario 1: This is...

The popout forms because a chemical reaction creates a substantial volume increase in the area immediately surrounding the aggregate piece. According to Mielenz (Ref. 1), this is a three-step chemical reaction. After the popout occurs, iron sulfide material becomes exposed to water and air.

Conc. Shrinkage vs Aggregate Size - Structural engineering ...

Jun 23, 2005 I believe the contractor would always prefer 20mm aggregate to 10mm aggregate due to the lower cost. The smaller the aggregate the higher the cost of the aggregate and also either a higher cement content or additional water reducing plasticiser will be needed to get the same workability.
