Frequently Asked Questions

GP Cement is your classic all-rounder cement, commonly used for:

  • Concrete slabs, footings, and driveways
  • Mortar for brick and block laying
  • General construction and repair work
  • Rendering and patching applications
  • DIY concreting projects

The "GP" in GP Cement simply stands for General Purpose, meaning this versatile cement can be used across a number of different applications.

GP Cement can be used for a number of applications, so your mixing ratios will vary depending on whether you are using it to create concrete, mortar, or render.

STEP 1: Place the required amount of cement, clean aggregate, and sand into a wheelbarrow, mixing tray, or concrete mixer. Thoroughly combine the dry ingredients before adding water.

STEP 2: Gradually add clean water while mixing until you achieve a workable consistency. Only add enough water to suit the mix, as excessive water can reduce the strength of the finished concrete.

STEP 3: Apply the mix as soon as it is prepared. Once placed, keep the finished job moist for approximately 7 days to help achieve the best results.

GP Cement is a base ingredient, meaning it is designed to be mixed with aggregates and sand to create concrete. Using GP Cement as a base ingredient gives you greater control over the mix ratios and allows you to customise your mix to suit your project.

This particular Builders Cement is a blend of Portland cement and fly ash that exceeds the requirements specified in Australian Standard AS 3972 for Type GB cement.

Builders Cement is a blended cement that contains additives to improve workability, while pre-mixed products such as concrete or mortar already contain the correct proportions of sand and aggregates for quick and convenient use.

From trusted suppliers, Cement Australia, our General Purpose Cement fully complies with the Australian Standards requirements for Type GP cement described in AS3972: General purpose and blended cements. It’s a premium Portland cement that blends with raw materials to suit your project.
