4. TYPES OF CONCRETE
BASED ON DESIGN OF CONCRETE
PLAIN CEMENT CONCRETE-
• MAIN CONSTITUENTS ARE CEMENT, SAND , COARSE AGGREGATE
AND WATER
CEMENT SAND COARSE AGGREGATE PCC

5. • IT HAS NO REINFORCEMENT
• THIS IS MAINLY USED IN CONSTRUCTION OF BUILDINGS ,
ESPECIALLY IN AREAS WITH LESS DEMAND OF HIGH
TENSILE STRENGTH
• IT IS ALSO KNOWN AS MASS CEMENT CONCRETE

DOME OF PARTHENON, ROME
WORLDS LARGEST DOME MADE OF
UNREINFORCED SOLID CONCRETE

7. • THE CEMENT CONCRETE IN WHICH REINFORCEMENT IS
EMBEDED FOR TAKING TENSILE STRESS
• VIRTUALLY ANY GEOMETRIC SHAPE OR
STRUCTURE CAN BE CREATED WITH RCC
• CONCRETE IS STRONG IN COMPRESSION
BUT WEEK IN TENSION AND STEEL IS
STRONG IN TENSION SO THEIR COMBINATION
GIVES A STRONG STABLE STRUCTURE
REINFORCED CEMENT CONCRETE

9. PRESTRESSED CONCRETE
• Form of concrete used in construction which is pre-stressed
by being placed under compression prior to supporting any
loads beyond its own dead weight. The compression is
produced by the tensioning if high-strength “tendons”.
• Classified into two ways:
1 . Pre-tensioning.
2 . Post-tensioning.

10. Pre-tensioning
• The steel wires or tendon are
tensioned first and the
concrete is poured later.
• Tendons tries to shrink back to
the original length but resisted
by the bond between the
concrete thereby transferring
compressive force to concrete.

11. • Concrete is poured first, allowed to
harden and then tendons are
tensioned later. Tendons are placed
in sheathing at suitable places in the
member before casting and later
after hardening of concrete.
• Done after the concrete attains
sufficient strength.
• Cables are used in place of wires and
jacks are used for stretching.
Post-tensioning

13. FERROCONCRETE
• FERROCONCERTE IS A FORM OF REINFORCED CONCRETE
USING CLOSELY SPACED MULTIPLE LAYERS OF MESH OR
SMALL DIAMETER RODS COMPLETELY INFILTRATED WITH IN
MORTAR

14. APPLICATIONS
• FERROCONCRETE IS RECOMMENDED TO MEET THE
FOLLOWING REQUIREMENTS:
• TO PRODUCE HIGH EARLY STRENGTH IN A WIDE ARIETY OF
CONCRETES, MORTARS AND GROUTS.
• TO FACILITATE THE EARLY DEMOULDING.
• TO REDUCE FORMWORK AT STRIKING TIMES

15. • TO HELP MAINTAIN NORMAL CONCRETE PRODUCTION
DURING COLD WEATHER.
• TO RESIST FIRE UP TO 750 C FOR A PERIOD OF 48 HOURS OR
EVEN MORE
• TO RESIST RUST,ROT,OR BLOW DOWN IN STORMS

16. CONSTRUCTION METHOD
• THE FIRST STEP IS TO
PREPARE THE SKELETAL
FORMWORK ONTO
WHICH THE WIRE
MESH IS FIXED WITH A
THIN TIE WIRE (IN
SOME CASE BY
WELDING )
• A MIN OF TWO LAYER
MES IS REQUIRED AND
DEPENDING ON THE
DESIGN UP TO 12
LAYERSHAVE BEEN
USED https://i.pinimg.com/736x/2e/52/f1/2e52f12a71b2a880

17. • THE SAND CEMENT
AND ADDITIVES ARE
CAREFULLY
PROPORTIONED BY
WEIGHING ,MIXED DRY
AND THEN WATER
• HAND MIXING IS
USUALLY SATISFACTORY
,BUT MECHANICAL
MIXING PRODUCES
MORE UNIFORM
MIXES,REDUCES
MANNUAL EFFORT AND
SAVES TIME

18. • AFTER CHECKING THE
STABILITY OF THE FORMWORK
AND WIRE MESH
REINFORMENT,THE MOTAR IS
APPLIED EITHER BY HANDOR
WITH A TROWEL AND
THROUGHLY WORKED INTO
THE MESH TO CLOSE ALL
VIODS . THIS CAN BE DONE IN
A SINGLE APPLICATION THAT
IS FINISHING BOTH SIDES
BEFORE INITIAL SET TAKES
PLACE

19. PROPERTIES OF FERROCONCRETE
• IT IS A VERY DURABLE,CHEAP AND VERSATILE MATERIAL
• LOW WATER CEMENT RATIO PRODUCES AN IMPERMEABLE
STRUTURES
• LESS SHRINKAGE,AND LOW WEIGHT
• HIGH TENSILE STRENGTH AND STIFFNESS
• BETTER IMPACT AND PUNCHING SHEAR RESISTANCE
• UNDERGO LARGE DEFORMATION BEFORE CRACKING OR HIGH
DEFLECTIONS

20. USES OF FERROCONCRETE
1.WATER PROOFING
FERRO CONCRETE
MEMBRANE WATER
PROOFING IS A STRUCTURAL
TREATMENT
-IT CAN NOT BE PUNCTURED
-RESISTS WEAR AND TEAR IS
PERMANENT WITH
NEGLIGIBLE MAINTANANCE
-SOLUTION TO CHRONIC
LEAKAGE

23. FERROCONCRETE IN SUNSHADES

24. FERROCONCRETE IN SCULPTURES

25. FERROCEMENT BUILDING
• FERROCEMENT IS USED IN FLOORS
ROOFS WALLS FOR RESIDENTIAL
PLACES AND OFFICE BUILDINGS
AND ARE FABRICATED USING
FERROCEMENT COLUMNS, BEAMS
AND PANEL SYSTEMS THAT HELPS
REDUCTION IN CONSUMPTION OF
CEMENT AND STEEL
• THE WEIGHT OF A
FERROCONCRETE BUILDING IS 50%
LESS THAN THAT OF RCC BUILDING

27. INSITU CONCRETE
• THE CONCRETE IS POURED INTO THE FORMS AT THE
BUILDING SITE
https://media3.picsearch.com/is?C4O-Ybm4DtUNNwlcQ_qFPyyEugdGrJI3MX3FeusdLAA&height=154

28. ADVANTAGES OF INSITU CONCRETE
• ELEMENTS ARE MANUFACTURED IN A CONTROLLED CASTING
ENVIRONMENT AND HAVE IT IS EASIER TO CONTROL MIX,
PLACEMENT AND CURING.
• IT PROVIDES HIGHER DEGREE OF INSULATION.
• BETTER WORKING CONDITIONS FOR THE BUILDING
OPERATIVES

29. DISADVANTAGES OF INSITU
CONCRETE
• NEEDS HIGH LABOUR NUMBERS
• ERACTION OF FORMWORK IS TIME CONSUMING
• THE QUALITY CONTROL IS DIFFICULT
• ONCE THE CONCRETE IS CAST ITS DIFFICULT TO DO ANY
MODIFICATIONS

30. PRECAST
CONCRETE
Precast concrete is a
construction product by
casting concrete in a
reusable mould or form
which is then cured in a
controlled environment
and then transported to
the construction site.

HOLD THE REINFORCEMENT INTO CERTAIN CONFIGURATION
theconstructor.org

44. MIXING AND POURING OF
CONCRETE

CHIPS , WATER INTO A MIXER AND THEN POURED INTO THE
FORMWORK UNTILL RIGHT LEVEL IS REACHED
https://media5.picsearch.com/is?TIrKjAfTc7c4itT-PLARI8tAj1RTXem

45. CURING OF CONCRETE
IT IS THE PROCESS IN WHICH THE CONCRETE IS PROTECTED
FROM LOSS OF MOISTURE AND KEPT WITHIN A REASONABLE
TEMPERATURE

46. • CONCRETE GAIN ITS STRENGTH ALONG WITH THE PASSING OF
TIME DUE TO HYDRATION REACTIONS INORDER TO
COMPLETE THE HYDRATION PROCESS OF CEMENT WE HAVE
TO KEEP THE CONCRETE STRUCTURE WET AND MOIST TO
ENSURE THAT THERE IS NO LARGE SCALE ESCAPE OF WATER
FROM THE MIX DUE TO EVAPORATION WHICH MAY
DETERIORATE THE QUALITY OF CONSTRUCTION.EEN CEMENT

STRESSES THAT ACT IN THE PLANE OF THE
STRUCTURE.
• USUALLY CONSTRUCTED OF CONCRETE
REINFORCED WITH STEEL MESH.
• SHELL CONSTRUCTION BEGAN IN 1920S. SHELL

62. SHELL STRUCTURES ARE SOMETIMES DESCRIBED AS :
SINGLE CURVATURE - A SHELL WITH ONE CURVED SURFACE.
- EG. VAULTS
DOUBLE CURVATURE- A SHELL WITH DOUBLY CURVED SURFACE.
- EG. DOMES

63. THIN CONCRETE SHELLS
• LIGHTWEIGHT CONSTRUCTION COMPOSED OF RELATIVELY
THIN SHELL MADE OF RCC, WITHOUT THE USE OF INTERNAL
SUPPORT.
• TYPES – BARREL SHELLS AND VAULTS
FOLDED PLATE
HYPERBOLIC PARABOLOID ( HYPAR)
DOME

64. BARRELS SHELL AND VAULTS
STRUCTURAL BEHAVIOR-
VAULTS: IT IS SAME AS CONNECTED PARALLEL ARCHES WHICH
TRANSMIT THE LOADS TO ITS SUPPORTS.
• MATERIAL USED SHOULD BE ABLE TO RESIST
COMPRESSION AND THE THICKNESS IS USUALLY HIGHER.
• SHAPE SHOULD BE AS SIMILAR TO THE
ARCH AS POSSIBLE TO ACHIEVE
OPTIMUM STRUCTURAL BEHAVIOR.

65. BARREL SHELL: IT CARRIES LOADS LONGITUDINALLY AS A
BEAM AND TRANSVERSALLY AS AN ARCH.
• MATERIAL USED SHOULD HAVE THE TENDENCY TO RESIST
BOTH COMPRESSION AND TENSION STRESSES.
• FOR RCC THE SPAN TO THICKNESS RATIO CAN BE
INCREASED BY PLACING THE BARS WHERE THE TENSION
FORCES ARE NEEDED.

67. FOLDED PLATE
• ASSEMBLIES OF FLAT PLATES RIGIDLY CONNECTED TOGETHER
ALONG THEIR EDGES.
• STRUCTURAL BEHAVIOUR –
THE EXTERNAL FORCES ARE TRANSFERRED
TO THE SHORTED EDGE OF ONE
FOLDING ELEMENT, THEN THE
REACTION AS AN AXIAL FORCE
IS DIVIDED BETWEEN THE ADJACENT
ELEMENTS AND THEN TRANSFERRED
TO THE BEARINGS.

69. HYPERBOLIC PARABOLOID
(HYPAR)
• A SURFACE WHICH IS CURVED IN TWO DIRECTIONS I-E IT HAS
A CONVEX FORM ALONG ONE AXIS AND CONCAVE FORM
ALONG THE OTHER AXIS.
• THE CURVATURE OF THE SHAPE REDUCES ITS TENDENCY TO
BUCKLE IN COMPRESSION WHICH MEANS THAT THEY CAN
ACHIEVE EXCEPTIONAL STIFFNESS.
• BY BEING BRACED IN 2 DIRECTIONS THEY EXPERIENCE NO
BENDING AND ARE ABLE TO WITHSTAND UNEQUAL LOADING
(DEAD OR LIVE).

(21 June 1891 – 9 January 1979)
• HE WAS AN ITALIAN ENGINEER
AND ARCHITECT
• HE STUDIED CIVIL
ENGINEERING AND PRACTISED
AS A BUILDING ENGINEER
• HIS AESTHETICALLY PLEASING
DESIGNS OF REINFORCED
CONCRETE WERE USED FOR
MAJOR PROJECTS AND ALSO
GAINED HIM NAME IN THE
ARCHITECTURAL FIELD.
