• Type I • Type II • Type III Do not mix or alternately use differing brands or types of cement, or the same brand or type of cement from different mills without prior written approval.
ASTM C150 for low alkal i cement except as follows:
• Cement shall have a total alkali content (sodium and potassium oxide calculated as Na 2O + 0.658 K2O) not exceeding 0.60 percent. • All cement types shall contain a maximum of 8 percent tricalcium aluminate (C3A). • The time- of-setting tests will be by either the Gillmore test or the Vicat test. • Types I and II maximum fineness (specific surface) as determined by AASHTO T 153 air permeability test shall be 430 m2/kg. If C 3S + 4.75 C3A is less than or equal to 90, the fineness criteri a does not apply.
