The steam curing temperature and duration of manufactured sand concrete result from the
comprehensive consideration of early strength growth rate and late strength. The effects of …

The objective of this paper is to investigate the hydration reaction and strength development
of calcium sulfoaluminate (CSA) cement mortar cured in various cold temperatures (ie, 5° C …

In 2021, the price of silica fume had fallen to 400 RMB/ton in some areas, while that of
cement had risen to 650 RMB/ton, which provided a realistic basis for applying silica fume in …

This paper deals with the correlation between the time evolution of the degree of hydration
and the compressive strength of Recycled Aggregate Concrete (RAC) for different water to …

This paper proposes a conceptual formulation for predicting and controlling the compressive
strength of Recycled Aggregate Concrete (RAC) mixtures, by explicitly taking into account …

In this paper, adiabatic temperature rise test was used to evaluate the effect of the type and
content of accelerator on cement hydration in shotcrete. Two kinds of accelerators, alkaline …

Steam-curing at elevated temperature involves a complex hygrothermal coupling action,
which greatly affects the hydration process, microstructure buildup and thus the mechanical …

Early-age voids and cracks can cause the mechanical qualities of concrete to deteriorate
and impair its long-term operating performance. Therefore, it is crucial to detect and assess …

This book reports on the physical and mechanical characterization of Recycled Aggregate
Concrete (RAC), produced through a partial-to-total replacement of ordinary aggregates with …

Large structures of massive concrete are an engineering problem due to cracking created by
thermal stresses. Nowadays, many constructions use large amount of concrete, like dams …
