  3. Methodsofmanufacture • Brickmakingatthebeginningofthe 20th century. • Madefromclay, shale, softslate, calciumsilicate, concrete, orshapedfromquarriedstone.Clayisthemostcommonmaterial, withmodernclaybricksformedinoneofthreeprocesses - softmud, drypress, orextruded. • ingredients: • Silica (sand) - 50% to 60% byweight • Alumina (clay) - 20% to 30% byweight • Lime - 2 to 5% byweight • Ironoxide - 5 to 6% (notgreaterthan 7%) byweight • Magnesia - lessthan 1% byweight

  4. SolfMudbricks • - SoftMudMethodisthemostcommon. • RawClay+ 25-30% Sand+ Water • Theshapedclayisthenfired ("burned“) • at 900-1000 °C • to achieve it’s strength,But in • modern brickworks, this is • usually done in a continuously • fired tunnel kiln.

  5. Drypressedbricks • Similartomudbrickbutstartswith a muchthickerclay. • It formsmoreaccurate, sharper-edgedbricks. • Greaterforceinpressingandthelongerburn • Makethismethodmoreexpensive

  6. Solid (left) and hollow extruded brick.

  7. Extrudedbricks • Claywith 10-15% water (stiffextrusion) or 20-25% water (softextrusion). • Moststructuralbricksaremadebythismethod, asitproduceshard, densebricks. • - Hollowinbricksarelighterandeasiertohandle, • andhavethermalpropertiesdifferentfromsolidbricks. • Cutbricksarehardenedbydryingfor 20 to 40 hoursat 50 to 150 °C

  8. Application • Bricks have been usedforbuildingandpavement for centuries. Untilrecently, almostallhouseswerebuiltalmostentirelyfrombricks. • Althoughmanyhousesarenowbuiltusing a mixtureofconcreteblocksandothermaterials, manyhousesareskinnedwith a layerofbricksontheoutsideforaestheticappeal.

  9. Characteristic Of Good Brick • - GoodThermalShockResistance • - Refractoriness UnderLoad • - HighMeltingPoint • - SatisfactoryPorosity.
