Answer 1

1)Precast concrete tower for turbine is a construction product produced with the help of casting concrete in a re usable mold or it is cured in good environment, transported to the construction site and lifted into place. The different tower segments are casted.
After casting and hardening of previous tower segment, next tower segment is cast coaxially on top of the first tower segment. After hardening the second tower segment is removed from the first tower segment. The step of casting a next segment on top of an earlier cast segment can be done again and again until all tower segments are casted. Finally tower is erect­ed by stacking the tower segments with the same position as at the time of casting.

2)1.Compared with steel and concrete tubular towersa number
of unique benefits can be said such as
they can give efficient on site and off site prefabrication
2.they do not require any specific design of formwork.
3. site prefabrication modules can be tailored to avoid the need
for special transportation.
4.it is easier to locate a precast concrete plant in close area to any future wind farm

3)1. PRECAST USES LESS CONCRETE THAN IN-SITU CONCRETE
2. PRECAST CONCRETE IS ENVIRONMENTALLY FRIENDLY
3. PRECAST CONCRETE IS A SAFE, LONG TERM, LOW COST INVESTMENT
4. Being manufactured in a factory-controlled environment, manufacturing precast leads to evoluted technologies in reuseable steel molds, gives in high quality products and less waste.
5.it will not emmit toxic fumes when exposed to fire nor will get affected by
6. It offers design flexibility thus gives winning results. Shapes, colours and textures can all be designed to suit.
7. off-site manufacturing takes place thusthere is less noise pollution and dust pollution

5)The best places for precast concrete wind turbines are in coastal areas, at the top rounded hills, open plain area and gaps and valleys in mountains at the places where the wind is strong and reliable. Some are offshore. And wind speed very high around 25 kmph

6)we can increase the tower heights easily while used precast method and engineers always prefer this method because -
in any country, tall towers with high hub heights have access to high wind speeds and steady wind conditions, both of which will increase the wind-energy-harvesting time and the total wind-energy production.

7) there are few papers on researchgate
And refer concrete structure for wind turbines reference book
