كواحد من قادة perlite ore is used in concrete الصناعة ، تسعى SBM دائمًا إلى الابتكار والتميز.
As consumers, we''ve seen expanded perlite used as a plaster, concrete aggregate and insulation material in the construction industry. However, since the production of expanded perlite requires onsite expanders or prior expansion and the distribution of the expanded product, it can be argued that raw perlite ore is a better pozzolanic fit for this application. Alternatives to Fly Ash. Oil ...

Perlite was then used to replace sand at 30, 40, and 50% by mass (resulting in concrete of a strength less than the targeted 30 MPa). The compressive strength of the control group concrete was increased by 25 and 50% (by increasing the cement content) for the next trial mixes. The workability of the fresh concrete was controlled to have a slump at 80100 mm. It was found that the 125% ...

Perlite is substituted for sand or heavier aggregates in concrete and plaster mixes to reduce weights and achieve better insulation and fire protection. Perlite is naturally incombustible, resistant to thermal transmission and lightweight. Using lighter perlite materials means that, in turn, structural building elements can be smaller, lighter and less expensive.
