Abstract— Computational Private Information Retrieval (cPIR) protocols allow a client to retrieve one bit from a database, without the server inferring any information about the queried bit. These protocols are too costly in practice because they invoke complex arithmetic operations for every bit of the database. In this paper, we present pCloud, a distributed system that constitutes the first attempt toward practical cPIR. Our approach assumes a disk-based architecture that retrieves one page with a single query. Using a striping technique, ....etc

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

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
