What happens if you use too much water in concrete?
Effects of too much mixing water Lower compressive strengths. Segregation of the concrete mix under certain conditions resulting in variable quality throughout the concrete mass. Cracking – with too much water, there will be lower tensile strength, and a tendency towards high shrinkage and subsequent cracking.
How do I work out how much concrete I need?
How to calculate concrete: Determine how thick you want the concrete. Measure the length and width that you’d like to cover. Multiply the length by the width to determine square footage. Convert the thickness from inches to feet. Multiply the thickness in feet by the square footage to determine cubic feet.
