Admixtures are not a solution for every problem when dealing with concrete mixes, but innovative admixtures can improve the properties of concrete at both the plastic and harden states and significantly enhance concrete’s performance, especially in terms of reliability and economy. But getting the admixture right is only one part of the equation; to achieve predictable outcomes the rheology must be controlled. This is where methods in early age strength evaluation are vital.

Overseas methods in early age strength evaluation using maturity tests can provide vital data to contractors to better tackle immediate challenges facing the concrete industry. Lack of an accurate strength estimation method at the early stages of construction often results in contractors waiting too long to move to the next action (e.g. stripping formwork) causing costly delays or acting prematurely and proceeding on insufficiently cured concrete which can lead to structural cracks, future durability and performance issues or even structural collapse.

This seminar will provide an overview of admixtures, how to control the rheology of concrete, design special concrete mixes and recent developments of early age strength development evaluation methods using maturity tests. Attendees will have the opportunity to ask these experts in-depth questions about admixtures, properties of concrete at fresh state and early age strength development and see applications on how it is used in practice.

Topic: Concrete Maturity Testing - Unlocking Early Age Strength in Structures

Early, rapid, and accurate in-situ estimation of the compressive strength of concrete is one of the major challenges for the concrete industry. A practical solution for such challenges can prevent millions of dollars of extra annual spending for the construction industry and owners of civil structures.
Concrete maturity is an index value that represents the progression of concrete curing. It is based on an equation that takes into account concrete temperature, time, and strength gain. Concrete maturity is an accurate way to determine real-time strength values of curing concrete. This presentation will discuss the concept of maturity testing, methods of engaging with the testing practice and an overview on its current roll out into the Australian construction industry.
