· Keep in mind that the standard level of strength for posttensioning is 75% and in some cases, your concrete can reach this level of strength sooner than expected. By employing the maturity method, you'll be able to closely monitor when your concrete reaches the necessary level of strength so you can move forward posttensioning as soon as possible.

efore the concrete is scooped into the moulds the moulds must be lightly coated in a mould release agent. This ensures that the concrete does not stick to the mould and makes it easier to remove the cube. When using a 150mm mould, the concrete sample is scooped into the mould in 3 equal layers (50mm) and compacted between each layer.
