�A series of investigations carried out by CECRI, (the results of which have been confirmed by the National Building Organisation, New Delhi, and the Central Building Research Institute, Roorkee) show that Indian Pozzolana cements offer less protection to steel subjected to aggressive conditions. Some recent foreign publications also suggest a cautious approach in using different pozzolanic cements. The durability factor for PPC is found to be 0.5 when compared to the OPC concrete. But if the use of PPC cannot be avoided the "Inhibitor" formulation developed by the CECRI may be used to improve the resistance of PPC concrete to a considerable degree�.

Views of cement manufacturing companies:

Pozzolana cements are much more durable, corrosion resistant and has every (best possible) things in their Pozzolanic cement products. And trying to get the approval from government to use the PPC in government projects.

Please put some light on this topic please

23 PERISH AS QUAKES ROCK JAPAN

October 25, 2004 -- OJIYA, Japan � Tens of thousands of people huddled in emergency shelters yesterday after a series of earthquakes in northern Japan flattened homes, toppled bridges and derailed trains, killing at least 23 and injuring as many as 2,000.
A 6.8-magnitude quake rocked the largely rural Niigata prefecture Saturday evening, rattling buildings as far away as Tokyo.

Several strong quakes followed through the night, and aftershocks jolted the area early this morning, one a magnitude of 5.6.

The government said 23 people were killed and 1,232 were injured.

Public broadcaster NHK, citing hospital data, said more than 2,000 were injured.

The dead included five children, the youngest a 2-month-old.

The quakes tore apart highways, burst water and sewage mains, and knocked out power to nearly 300,000 homes.

Some 61,000 people, many of them elderly, had to be evacuated.

Hospitals were so overwhelmed, the injured were being treated in the hallways.

The Islands of Japan lie on a ring of seismically active plate boundaries that surround the Pacific Ocean known as the Ring of Fire. Earthquakes throughout Japan are caused by the relative motion of several major and minor tectonic plates including the Pacific plate, the Philippine Sea plate, the Okhotsk plate, and the Amur plate. Earthquakes result from slippage on the interface between the plates and on faults some distance from the plate's boundaries. This thrust earthquake, of October 23rd 2004, occurred within the Okhotsk plate about 350 km west of the Japan Trench where the Pacific plate subducts beneath the overriding Okhotsk plate. Within the last 30 years, there have been several significant earthquakes in region nearby this earthquake. These include a June, 1964 magnitude 7.4 quake to the north and an April, 1995 magnitude 5.4 quake that occurred 90 km to the north. Since 1900, the country of Japan has suffered nine devastating earthquakes . These include the 1923
magnitude 7.9 earthquake that triggered the great Tokyo fire and the more recent 1995 6.9 Kobe earthquake .
With regards to you.
