Metromix concrete driveways

  1. 1. METROMIXCONCRETE PREMIX CONCRETE, CONCRETE DRIVEWAYS
  2. 2. CONCRETE • The word comes from the Latin word Concertos (meaning compact or condensed). Cement + Coarse aggregate + Fine aggregate + Water + Chemical Admixtures • Concrete is a mixture of binding material, fine aggregates, coarse aggregates and water in suitable proportions. • Concrete is used than any other man made material in the world. As of 2006, about 7.5kms of concrete is made every year.
  3. 3. AGGREGATE AND ITS TYPES • Aggregate is a general term applied to those inert or chemically inactive materials which, when bonded together by cement form concrete. • Cement and lime are generally used as binding materials, fine aggregates are Sand, Surkhi etc. while coarse aggregates are crushed stones, gravel, broken pieces of bricks, etc.
  4. 4. PROPERTIES OF CONCRETE • It is a brittle material • Strong in compression but weak in tension. • To overcome the weakness steel bars are used in construction. • Our Site http://metromixconcrete.com.au/services/
  5. 5. MANUFACTURING OF CONCRETE • Mixing • Transporting • Placing • Compacting • Curing
  6. 6. TYPES OF CONCRETE • Cement Concrete • Lime concrete • Reinforced Cement concrete • Pre-stressed concrete • Precast concrete • Mass concrete • Light weight concrete • Non-fines concrete • Colored concrete
  7. 7. PREMIX/READY-MIX CONCRETE • Ready-mix concrete is concrete that is manufactured in a factory or batching plant, according to a set recipe, and then delivered to a work site, by truck mounted in–transit mixers. • Also referred as the customized concrete products for commercial purpose. • It is delivered to the customer's construction site in a freshly mixed and plastic or unhardened state.
  8. 8. CONCRETE DRIVEWAYS • Driveways (a type of private road), can be made decorative with materials like concrete called as concrete driveways. • Also other materials like decorative brick, cobblestone, block paving, asphalt, and decomposed granite can also be used.
  9. 9. PROPERTIES OF CONCRETE IN PLASTIC FORM • Good workability • No segregation • No bleeding
  10. 10. PROPERTIES OF CONCRETE IN HARDENED FORM • Adequate strength • Durability • Impermeability • Elasticity • Low shrinkage • Least thermal expansion
  11. 11. ADVANTAGES • Economically used in the long run as compared to other building materials. • It possesses high compressive strength and also resist well to weathering effects. • Green or Fresh concrete can be molded to any size and shape. • Durable, Fire resistance and requires very little maintenance.
