I was always led to believe that coolant froze if it didnt have water added....but I never had the ***** to find out if it didnt so have always added water as well

Think you're looking at "4life" here, that stuff is a special coolant mix that goes straight in the engine, no water added, same performance and lasts 10 years. I bought 2x 5 ltrs the other day for £24 - saves buying distilled water to mix with normal coolant/anti freeze.

as above when i get a new bottle of antifreeze i tip half the antifreeze out into a spare empty bottle and then top up both half full bottles with water. job done 50/50 tip it in from the bottle then.

I use neat coolant in mine and did in the previous few cars without any problems. Used to do it years ago when i was racing oval circuit cars.Could never get enough cooling when following other cars closely and water just boiled away to easily. It has a higher boiling point than water hence we never lost so much from boiling when we were really giving them some beans

Water as far as im aware is neutral ph so not corrosive.... chemical reaction with iron blocks causes corrosion to occure,not a good idea to run just water alone in alloy blocke either,antifreeze is a corrosion inhibitor ....... 50-50 mix is fine

Would running "just water" cause the coolant to boil up and prssurise the system, in view of the fact the coolant helps the car from overheating

There seems to be some confusion as to what coolant is compared to just water..... generally its a mix of water to ethelyne clycol antifreeze in a mix from 25%-50% depending on how cold the car is subjected to in winter conditions,antifreeze is needed to prevent the water from freezing (obviously) and causing severe damage to the engine as it expands (core plugs are designed to pop out to prevent this but not reliable) and to prevent corrosion building up.... race cars/bikes generally are prevented from using antifreeze when on tracks as any spillage can be hazardous to following competitors due to its slippy nature,so water alone will work in the cooling system,but for general road use A/F is a must,so if you have cooling issues with your car its the system itself not the cooling medium thats at fault.... check general items for leaks,thermostat for correct operation and if its pressurizing check the head gaskets.....
