Joint sand used for paver applications should be a course, washed concrete sand. This sand takes more time to get into the joints, but is also more difficult to wash out. Do not use silica sand or mason sand. The joint sand should also be completely dry. If the sand you have is damp, spread it out to dry before using. Wet and damp sand will prevent it from flowing freely into the paver joints.
Drinking eight cups or two litres of water a day is longstanding advice. But is there any scientific basis for it, asks Dr Chris van Tulleken.
Learn how much water you should drink every day. You need half of your body weight in ounces of water daily. This is the number most individuals recognize and aspire to for their daily water intake. A good rule for drinking the right amount of water is to drink one glass of water each hour. An average person should drink this amount of water daily. It is the recommended daily water intake amount to drink 12 glasses of water. If you drink alcohol, you should drink at least an equal amount of water. Drinking a good amount of water could lower your risks of a heart attack.
