CONCRETE POLYMER
 Polymer is that big molecule weighing materials referred as
polymer, having structure and nature of complicated
because of amount of atom.
 A number of insoluble polymer materials generally solvent
and even so can be dissolve, its very high viscosity.
 Generally coalesce kovalen, liquid polymer materials
considerably jell and not condense. Materials that cannot
merger ravelled because heat become carbon, final phase
without evaporation.
 Polymer concrete: representing concrete materials which is
impregnation with polymer so that yield a[n materials which
in character is better the than its own concrete.

NATURE OF TYPICALLY MATERIALS POLYMER
Strong and light product can be made.
Good Electrics insulation. And earn also made by conductor with
alloy.
Very well in water resilience and chemical essence resilience.
Product enough differ in character.
Cheaper polymer.
Less hold up to heat.
Hardness of very surface less.
Less hold up to destroyer.
Easy to loaded by electrics electrostatically.
Some materials hold up abrasi, or have small coefficient of
friction.

COMPOSITE OF POLYMER CONCRETE
Requirement mount, Demand construction:
– Strength.
– Flexing, and.
– Durabel.
Make-Up of efektifitas.
1. Repair to the quality of concrete.
2. Merger of making technology various composite base on cement.
Polymer concrete usually hold up to corrosive environment.
Composite of polymer concrete.
Concrete strenghtened by polymer (PIC)
1. Concrete cement polymer (PCC), pasta mixture cement with aggregat
which have been added by monomer before setting.
2. Polymer concrete, representing bound by aggregate is polymer binder.
3. Concrete strenghtened by fibre (FRC)
4. Polymer concrete strenghtened by fibre.
Its process can be conducted by Termal, katalitik, and radiation.

STEEL
Iron and steel at most weared upon which industry
representing source very big, where some of determined by its
economic value, but most importantly because in character
which vary. That is that the materials have various nature of
from hardest made easy and mellowiest until keen and even
also for the knife of cutter can be made, or any kind of with any
form can be made with moulding. Of iron element various
metal structure form can be made, that is why steel and iron
referred by rich materials with nature of. Steel have the
important mixture is carbon. Besides carbon at steel and iron
consist in about 0,25% The, 0,3-1,5% Mn and other pollutant
element like P, S, etcetera
