Mapeair SA-50 is a specifically developed synthetic multi-component air entraining admixture for stabilizing superior quality air-void systems. Mapeair SA-50 will produce a fine air-void structure in all concrete applications including mixtures which contain low alkali cement or supplementary cementitious materials. Mapeair SA-50 is formulated specifically for ready-mix and precast concrete applications and conforms to ASTM C260 and CSA A23.1.
