Understanding factors influencing the phase developments in hydrothermally cured cement-based systems: An overview

Abstract

The hardening of concrete as well as other materials based on calcium silicates is accelerated by the use of saturated stearn under pressure in an autoclave. The principal strength-producing phase in autoclaved calcium silicate based materials is l.1nm tobermorite (tobermorite). Due to tobermorite's significance, there is great interest in optimising the conversion of tobermorite from C-S-H. This article provides an updated and integrated overview of the current understanding of factors influencing the phase developments pertaining to hydrothermally cured cement-based systems.
