1998-1-1 Japanese definition of expansive admixture explains that 'Admixtures, when mixed with cement and water, produce ettringite (3CaO- Ai203CaS04-32H20) or calcium hydroxide (Ca (OH)2) by hydration reaction to expand the concrete'. Table 1 shows the physical properties and chemical compositions of both 'ETTRIN- GITE series' and 'LIME series'.
