- Which component occupies the most weight and volume in concrete?
Cement
Sand (Fine Aggregate)
Crushed Stones (Course Aggregate)
Water
- Low Heat Portland Cement is preferred in mass concrete work such as dams because...
Rapid hardening of concrete is required for such structures
They have higher ultimate strength
Development of cracks is minimized
- In the making of concrete,
Water reacts with stones to give the strength to concrete.
Stones and sand react with each other to give the strength to concrete.
Cement reacts with sand to give strength to concrete.
Cement reacts with stone to give strength to concrete.
Cement reacts with water to bind all the materials together that give strength to concrete.

Using a flow chart diagram EXPLAIN in detail the various proformas used for preparation and implementation of development schemes. All the proformas should be in proper sequence and with sufficient details showing purpose and requirements of each proforma. The flow chart diagram can be drawn on a paper or any computer tool can be utilized for this purpose. The diagram should be sufficiently detailed and shouldn't be a copy of already available figures.

1. Define the terms "geodetic height", "geoidal height", and "orthometric height", present the equation that expresses the relationship between the geodetic height and orthometric height, and state which one these heights are measured by GNSS survey method.
2. What are the geocentric coordinates in meters of a station which has a latitude of 44°53′52.1918′′ N, a longitude of 68°40′07.3487′′ W and height of 130.405 m (use the WGS84 ellipsoidal parameters)?
3. The geodetic heights of two stations are 324.685 m and 309.879 m, and their orthometric heights are 356.496 m and 341.707 m, respectively. These stations have model-derived geoid heights of −31.828 and −31.836, respectively. What is the orthometric height of a station with a GNSS measured height of 305.645 m and a model-derived geoid height of −31.802 m?
4. A GNSS survey has a reported error of ±(12mm + 2ppm) at a 95% probability. What is the error for a control baseline with a length of 4 miles at the 95% probability?
