Ready-mix concrete is a versatile material used in a large number of applications—great news—but it means ordering it can require thinking through a few different variables to make sure you're getting the right product for your job.
MaterialsLink smart ordering system provides a step-by-step guide to ordering ready-mix-concrete which is easy to use and can make sure everything important is covered. In case you want some more information, the below are a few pointers on getting the right mix for your job.
Concrete is made by mixing four things together:
3. Aggregates (sand and crushed rock)
4. Admixtures (if required)
The amount of each component will affect the performance of the concrete and is adjusted to change the strength, durability, cohesiveness and workability of the concrete.
Our suppliers generally use the following colour oxides:
When ordering concrete it's important to make sure the supplier knows what you're using the product for so that they can mix the product in the appropriate way. The key things that concrete suppliers need to know in an order are:
Delivery cost can be a significant component of the overall cost of concrete for a job so it's important to make sure you're using suppliers that are in your area. Fortunately, MaterialsLink does this for you when you order through our platform.
What you're using the concrete for
The amount (volume in m3) of concrete you need as well as what you're using it for (e.g. house slab, multistorey building) and how you're going to place the concrete (pump, shute from the truck, carry in a wheelbarrow) are all important details to give when ordering. This will determine the required strength/class of concrete, the workability of the concrete (slump) and how porous the concrete needs to be (affected by the size of aggregate used).
MaterialsLink can guide you through this process using our online ordering form and the concrete provider may be able to give advice however it's a good idea to consult an engineer, architect or qualified builder if you're unsure about what exactly is required for your job.
GETTING VOLUME RIGHT
You should order more concrete than the exact volume you've calculated as wastage is a normal part of the concreting process. Cement Concrete & Aggregates Australia recommends a 10% over order for most jobs.
