basalt as concrete aggregate

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.

Mechanical properties of epoxy/basalt polymer concrete

We found that increasing the amount of epoxy resin to the basalt aggregates to 25 wt% improved mechanical properties of the concrete. After determining the optimum weight percentage of basalt in epoxy, the mechanical properties of the optimized PC were experimentally investigated at three different temperatures 50°C, 75°C, and 100°C.

Model Test on Bearing Characteristics of Basalt Fiber

It can be seen from Tables 2 and 3 that the basalt fiber contributes to the improvement of the compressive strength and the bending strength of the concrete. After the basalt fiber is added to the plain concrete, a reliable network structure is formed in the concrete, which cooperates with the aggregate to bear the stress.
