Variation in raw materials and fuels are likely to result in changes in kiln conditions and consequently, to some extent at least, to changes in the concrete. Of course, some changes may be for the better, but unless they are maintained consistently, the result will be variability in the production opf concrete. More Info

Back to Basics - Pumping Concrete

We take the equipment for granted too often because normally when everything is going well our level of confidence is high. We find ourselves “in the groove“ and we do our jobs and make it look easy to observers. What separates the best ops from the average is how the sudden, unexpected interruption of their ‘rhythm’ is handled. These interruptions can often take place in milliseconds and how quickly and appropriately the operator reacts can mean the difference between a successful outcome with a signed invoice, or a failed pour.

Time dependent deformation of fibre reinforcement

Failure to account for creep and shrinkage of the concrete can lead to a serious under‐estimation of the extent and severity of cracking, as well as long‐term curvatures and deformations.

The inclusion of steel or polypropylene fibers in the concrete mix can substantially improve the serviceability characteristics of reinforced concrete members. For fiber reinforced concrete (FRC) members, the fibers enhance the post-cracking stiffness, thereby reducing the short and long‐term deflections and significantly reduce the width of cracks and the spacing between them.

From Cylinders to Cores - What does it mean for design

Core tests are generally performed to assess whether suspect concrete in a new structure complies with strength-based acceptance criteria or not. In addition, it is critically used to determine in-place concrete strengths in an existing structure for the evaluation of structural capacity.

Taking core samples from concrete structures is required for comprehensive assessment of durability and structural performance of the structure.
