901.01 Hydraulic Cement
Provide hydraulic cement, selected from the Department’s Producer List, that conforms to the following for the kind and type specified or allowed: Portland cement ................................ ...................... AASHTO M 85 Portland blast -furnace slag cement (Ty pe IS) ....... AASHTO M 240 Portland-pozzolan cement (Type IP) .................... AASHTO M 240 Portland-limestone cement (Type IL) ................... AASHTO M 240 The maximum allowable equivalent alkalis is 0.60% for all cements and blended cements used in concrete riding surfaces with aggregates meet ing the requirements of 903.24. This includes Class CP, A Paving, and DS concrete mixtures. Use Type I, Type IL, or Type IS cement unless otherwise specified. Do not mix different types of cement. Provide suitable means for storing and protecting the cement against dampness. The Engineer will reject cement that has become partially set or that contains lumps of caked cement. Ensure that the temperature of the cement at the time of delivery to the mixer does not ex ceed 160 F. Do not use cement containing air -entraining materials. 901 SECTION 903 – AGGREGATES
