17. Aggregates are those chemically inert materials
which bonded by cement paste form concrete .
Fine Aggregates
e.g. sand
Coarse Aggregates
e.g. stone chips

18. Sand



fine aggregate
form of silicate of small grains
formed by the decomposition of sandstone due to various weathering
effects.
Classification based on fineness
 Fine
sand: FM= 0.1-0.5
 Medium sand: FM= 0.8-1.25
 Coarse sand: FM= 2.75-3.20

19. Classification according to source

20. Extraction of sand from riverbed
Transportation by steamer
Carried by pipes
Transportation by truck

21. Mainly river sand is used in our country.
In local market there are two types of river sand:
Sylhet Sand (FM 2.5)
Local Sand (FM 2)

22. Sylhet Sand
In local market there are three types of sylhet sand available.
Sand from Fajilpur
Sand from Sunamganj
Sand from Dayer

25. Coarse aggregate is that aggregate whose
particles completely pass through 7.5 cm
mesh sieve and which are entirely retained
on 4.75 mm sieve.

Price: 65 tk /cft.

32. Rebar
(Reinforcement bar)



Rebar, a portmanteau for reinforcing bar or
reinforcement bar, is commonly used in reinforced
concrete and reinforced masonry structures.
It is usually formed from carbon steel.
Concrete is very strong in pure compression, but
relatively weak in tension .Steel reinforcing helps
share the tensile stresses

33. Classification of Rebar
According
to
pattern:
• Deformed
(have repeating
pair of edges)
• Straight
(no edges)

34. According
to Grade
• grade 40(equivalent of
metric grade 280), which
can resist tensions of 40
ksi.
• grade 60(equivalent of
metric grade 420), which
can resist tensions of 60
ksi and
• grade 75(equivalent of
metric grade 520), which
can resist tensions of
70ksi.

59. • Green Cement
 Produced by using Recycled Materials
 doesn’t emit Carbon-Dioxide, but absorbs it
 Resists Sulphate Attack
 Resistant to Chemical Attack
 Resistant to Heat
exposure
 Stronger than
ordinary cement

60.  FRP products help in reaching 3 times the strngth of
steel in 24 hours
 Retrofitting an
existing structure
is needed when
crack develops
 Jamuna
