This document provides information about concrete, including its composition, uses, manufacturing process, types, and properties. Concrete is a mixture of cement, coarse aggregate, fine aggregate, and water. It is the most widely used man-made material in the world. Aggregates give body to concrete while cement acts as the binding agent. Concrete has high compressive strength but is weak in tension, so reinforcing steel bars are often added. The manufacturing process involves mixing, transporting, placing, compacting, and curing concrete. Common types include reinforced concrete and precast concrete.

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. 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. 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.

5. MANUFACTURING OF CONCRETE
• Mixing
• Transporting
• Placing
• Compacting
• Curing

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. 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. 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. PROPERTIES OF CONCRETE IN PLASTIC
FORM
• Good workability
• No segregation
• No bleeding

10. PROPERTIES OF CONCRETE IN
HARDENED FORM
• Adequate strength
• Durability
• Impermeability
• Elasticity
• Low shrinkage
• Least thermal expansion

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.
