Hardened Concrete Testing Sandberg

Once concrete has hardened it can be subjected to a wide range of tests to prove its ability to perform as planned or to discover its characteristics if its history is unknown. For new concrete this usually involves casting specimens from fresh concrete and testing them for various properties as the concrete matures.

Can We Really Measure Cement Content In Hardened Concrete

We are regularly asked to determine the amount of cement in hardened concrete and mortar. The request is normally made for one of two reasons; the most common being that something has gone wrong and the cause and/or blame for the problem is thought to be related to cement content.

The Effect of Aggregate Properties on Concrete

The shape and texture of aggregate affects the properties of fresh concrete more than hardened concrete. Concrete is more workable when smooth and rounded aggregate is used instead of rough angular or elongated aggregate. Most natural sands and gravel from riverbeds or seashores are smooth and rounded and are excellent aggregates.
