Abstract EN
Reactive powder concrete (RPC) mixtures are reported to have excellent mechanical and durability characteristics.
However, such concrete mixtures having high amount of cementitious materials may have high early shrinkage causing cracking of concrete.
In the present work, an attempt has been made to study the simultaneous effects of three key mixture parameters on shrinkage of the RPC mixtures.
Considering three different levels of the three key mixture factors, a total of 27 mixtures of RPC were prepared according to 33 factorial experiment design.
The specimens belonging to all 27 mixtures were monitored for shrinkage at different ages over a total period of 90 days.
The test results were plotted to observe the variation of shrinkage with time and to see the effects of the key mixture factors.
The experimental data pertaining to 90-day shrinkage were used to conduct analysis of variance to identify significance of each factor and to obtain an empirical equation correlating the shrinkage of RPC with the three key mixture factors.
The rate of development of shrinkage at early ages was higher.
The water to binder ratio was found to be the most prominent factor followed by cement content with the least effect of silica fume content.
