Order Concrete
Concrete is bought and sold by the cubic meter volume. Specifications for concrete normally include a requirement for a certain design strength (mpa), and also slump (water ratio).
How to order
- To ensure Campbellfield Concrete & Mini Mix has adequate time to prepare your premixed concrete and to meet your requirements, place your order at least one week (7 days) prior to the delivery date.
- All orders are subject to availability, and orders that require testing should have testing booked at the time the original order is placed. Confirmation of order detail and testing will be made 24 hours before delivery. Short notice orders will be considered on a case by case basis, dependent on availability.
- Weekend and night deliveries can also be ordered on request, but advanced notice is required.
- Calculating the volume of concrete for your order.
- Estimates should be based on site measurements rather than drawings or plans, and allowances made for on-site wastage.
- Orders should also factor in variations in slab thickness, distortion of formwork, over excavation, un-compacted sand, and uneven sub-grade levels.
- Plus or balance loads are subject to truck availability and may incur additional fees.
Specify Strength, Aggregate size & Slump
- A standard strength grade of N20, N25, N32, N40 or N50 should be specified.
- Strength grades above 50 are considered Special Class concrete.
- An aggregate size of 14mm is supplied as standard, unless 7mm or 20mm aggregate sizes are specified.
- Aggregate size can also be determined by placement method, reinforcement spacing and concrete element thickness.
- The required slump between 20mm to 120mm should also be specified to achieve the required concrete workability. Standard Slump is 80mm.
- Water should not be added to the concrete on site to increase slump, as this can compromise concrete quality.
- Campbellfield Concrete & Mini Mix needs to know the method that will be used to place the concrete, such as a chute or pump, the type of pump and size and length of the line.
- The rate of concrete placement should also be specified to help production and schedule deliveries to match.
- Pump placement and accessibility also need to be considered.
- The size of truck and traffic management should be planned to ensure there are no delays on the day of the pour. Safe site access must be considered. This includes consideration of the size of the delivery truck and traffic management planning to ensure there are no delays on the day of the pour. Pump placement and accessibility also need to be considered.
