REACTIVE POWDER CONCRETE


INTRODUCTION
A composite material & ultra high strength with mechanical properties.

Mixture of fiber reinforced, super plasticized, silica fume, cement & quartz sand

with very low water cement ratio.

Quartz sand used instead of ordinary aggregate. Therefore increases compressive

strength.


COMPOSITION
It is composed of similar modulus of elasticity and size increasing homogeneity

reducing differential tensile strain.

The material having the largest partic ....etc

History of Portland cement
Joseph Aspdin, a Leeds builder and bricklayer took patent of portland cement on October 21, 1824. The name of portland was given owing to the resembalance of this hardened cement to the natural stone occuring at Portland in England. German, British and ASTM standard specifications for Portland cement were drawn in 1877, 1904 and 1904 respectively. In India also Portland cement was first manufactured in 1904.

GEO POLYMER CONCRETE-Concrete without cement


Whatâ„¢s wrong with cement concrete?
Many concrete structures deteriorate after 20 years.

Cement production releases high amounts of CO2 to the atmosphere(1tonne of cement production releases 1tonne of CO2) thus contributing to 7% of world CO2 emissions.

Cement is one of the most energy intensive material.



How to reduce the use of cement
Partially replace the use of cement in concrete.
example: high volume fly ash concrete


Develop altern ....etc
