Introduction

The fastest route to reduce CO₂ emissions from cement and concrete is either to replace the clinker in cement, or cement in concrete, with a supplementary cementitious material (SCM). The SCM which is sufficiently abundant to serve the industry world-wide is clay.  This talk goes through all aspects of calcined clay as an SCM; what it is, how it is produced, how does it react with cement as well as what the benefits are when using it in concrete in terms of strength development and durability. The challenges and potential benefits of extremely high calcined clay loadings are also addressed.

Who should attend

This free to attend lecture will be of interest to all those who are involved in the design, specification, production and construction of concrete. Those who should attend include ready-mixed and precast concrete producers, concrete technologists, cement producers, design engineers, consulting engineers and engineers in contracting and sub-contracting firms.

Speaker Biography
