What is minimum pressure gauge for GI testing?
Komal Bhandakkar
Minimum pressure gauge for galvanized iron testing : Minimum yield strength of finished top tube should be 50000 psi Minimum tensile strength for the finished tube shall be 55000 psi The mechanical property of the finished surface of the cube is mainly depended upon the tube size and gauge. GenerallRead more

Lime stabilization with deep injection :
yes definitely it is possible that the embankment settlement can be reduced at embankment junction by lime stabilization with deep injection
The process of injecting a lime slurry into the subsurface up to some depth of some feet it is one of the innovative and comparatively very good technique for an engineer as well as for labour.
The main purpose of constructing climb up to some depth is to fill voids with a chemical compound
Thank you.

In OPC, the main alkali is cal. Hydroxides formed from limestone, the cal. Carbonate. The second material in OPC is silica in the form of sio2 and aluminate to some extent. This proportion of silica and alumina wrt ca(oh) 2 mainly decides the properties of cement.
When fly ash or any other substances like slag, rice husk ash, quartz, or feldspar (all contains silica) is added to some extent with OPC – the result is PPC. This PPC takes a long time to harden, the hydration at a considerable rate even continues for months together. But after a prolonged period, it achieves qualities like good waterproofing, weather resistance, and strength equal to or greater than that of OPC, with a lower cost than 100%OPC.
This unique quality of OPC, that it achieves 90 % of its strength in 28 days, makes it vulnerable to replace lime or every cementitious material.
So to achieve the equal or more strength than OPC with less cost – activation of today’s pozzolanic material, the coal fly ash, is mixed or activated with sodium hydroxide before it is acted with cal oxide/hydroxide. Experiments with diff. Percentage of activated fly ash has shown very encouraging results with a higher strength but not before three months curing. Research is going on with diff. percentage of silica and aluminate with sod. hydroxide to achieve quick strength.
In future this sod. hydroxide may replace the requirement of limestone completely for the making of cement.

All the 5 are positioning system used for navigation purpose. The different positioning system is originated from different countries. the positioning system you mentioned belongs to different countries and because of that names are different.
- GPS(GLOBAL POSITIONING SYSTEM) is made by the United States.
- QZSS(QUASI-ZENITH SATELLITE SYSTEM). It is made by Japanese.
- BEIDOU(1 & 2) -it is a satellite navigation system of China.
- GALILEO– this is a European positioning system which is divided into three parts i.e space, ground, the user.
- GLONASS– it is a Russian version of the positioning system has five versions till now.

GPS (Global Positioning System) and GLONASS (Global Navigation Satellite System) are two systems of satellites with the primary objective to provide an accurate positioning in terms of latitude, longitude and altitude to any reciever on the planet surface.
GPS is a system launched and maintained by the US while GLONASS by Russia. GPS was launched four years earlier than GLONASS. The latter began production in the USSR days back in 1976 and was launched in 1982. GLONASS after being refueled in Vladimir Putin’s precidency has put up all 24 geostationary satellites required to provide complete coverage. GPS on the other hand was launched with 22 and now has 31. GPS is overall considered to have a better accuracy though GLONASS has a better accuracy as we go closer to the poles.

As a civil engineering point of view for accurate measurement of any material weight batching is preferred over volume batching for large constructions.
Refer IS 4925(2004) 40 tales of concrete batching plants and their volumes
- The volume of transit mixer is around the 6.1-metre cube.
- The volume of the batching plant is based upon the size and quantity of manufacturing capacity. So it may vary from plant to plant according to requirement.
- Also, you can prefer a mix design of concrete to get an idea about transit mixer and batching plants in brief.

Dear student,
Nowadays we use IS 3370:1965 for water tank design which permits only the working stress method.
The reason behind the design of water tanks using the working stress method only are as follows;
- Serviceability of working stress method is more as compared to Limit state method and hence the lifespan of the structure will automatically extend.
