“…Studies conducted by Hekal et al [89] regarding the effect of SNSF on the formation of ettringite observed that it retards the reaction and leads to smaller crystal formation with increasing amounts of the sulfonated HRWR. However, an optimum level of 0.6% of SNSF has been seen by Collepardi et al [90], where the hydration of tricalcium aluminate in the presence of gypsum has shown no difference to that in the absence of the admixtures.…”

This review provides the hydration and volume expansion mechanism of expansive materials, with the goal of utilizing them in the development of sustainable mining methods. The main focus of the review will be the newly developed non-destructible rock fragmentation method, slow releasing energy material agent (SREMA), which is a modified soundless chemical demolition agent (SCDA). The review aims to address one of the main gaps in studies related to SREMA, by presenting a thorough understanding of the components of SREMA and their mechanisms of action, leading to volume expansion. Thus, this review would act as a guide for researchers working on using expansive materials for rock breaking. As many literatures have not been published regarding the recently discovered SREMA, studies on cements, expansive cements, and soundless chemical demolition agents (SCDA) were mainly considered. The chemical reactions and volume expansive processes of these materials have been studied and incorporated with the additives included in SREMA, to understand its behavior. Literature containing experimental studies analyzing the heat of hydration and microstructural changes have been mostly considered along with some of the heavily discussed hypotheses regarding the hydration of certain components, to predict the volume expansive mechanism of SREMA. Studies related to SREMA and other similar materials have shown drastic changes in the heats of hydration as the composition varies. Thus, SREMA has the capability of giving a wider range of expansive energies in diverse environmental conditions

“…Collepardi and co-workers (24) in their study of the combined effect of lignosul f ona te and alkali carbonate on tetracalcium aluminoferri te hydration noted a strong negative charge in the zeta potential caused by the simultaneous addition of lignosul f ona te and alkali carbonate. They speculated that both the strong retarding action and the dispersing effect caused by the negative charge in the zeta potential could explain the liquefying effect of the admix-…”

They are also grateful to Mrs. Janet Lovell for her fine work in preparation of some of the laboratory specimens for various studies in this research. The untiring efforts of Dennis Eliasen and Paul Tourney, undergraduate student assistants, in preparing concrete specimens and the diverse help provided during the course of this study is very much appreciated. The work done by the staff at the Chemistry Laboratory of the Materials and Testing Division, Indiana State Department of Highways (ISDH) , Indianapolis, in analyzing some samples is very much appreciated. Special thanks to Mr. Jackson and Mr. Richardson of that organization. Loan of certain equipment by the Research and Training Center, ISDH, West Lafayette, and suggestions provided by Mr. Barry Partridge of that organization are much appreciated. The financial support of the Indiana Department of Highways is also gratefully acknowledged as is the advice provided by personnel of the DOH and FHWA through individual contact and the Study Advisory Committee.
