Introduction The purpose of this document is to provide guidance on constructing residential concrete footpaths complying with the Australian standards. The document combines the
Cement Standards and Concrete Standards. ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.
The American Concrete Institute. Founded in 1904 and headquartered in Farmington Hills, Michigan, USA, the American Concrete Institute is a leading authority and resource worldwide for the development, dissemination, and adoption of its consensus-based standards, technical resources, educational programs, and proven expertise for individuals and organizations involved in concrete design ...

The compressive strength of concrete pipe made to Australian and New Zealand Standards is usually in the range of up to 60 MPa and above. The strength of the pipe is dependent on the materials used in the concrete mix, such as aggregates, cementitious material, and additives.
Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.
We mix all our concrete from locally sourced Western Australian sand, stone and cement in standard mixes or customised for your project. Now the DIY handyman can have the same professionally mixed quality concrete that the big commercial job sites use, at a cost-effective price.
