Abstract

A unitized, self-indicating, neutralizing composition comprises a neutralizing agent, a binding agent, and a pH indicator. The composition may optionally further include a disintegrant. The composition is convenient to use and is especially useful in the neutralization of wash water from cementitious compositions.
