Hydraulic Cement

701.01Hydraulic Cement. Hydraulic cement shall conform to the requirements of the

following specifications for the type specified or permitted:

Portland Cement ASTM C150 Blended Hydraulic Cement ASTM C595 All concrete, including precast, prestressed and pipe shall be constructed with one of the following hydraulic cements unless permitted otherwise.

The cement shall be subject to sampling and testing by the Department. Test results that do not meet the physical and chemical requirements may result in the suspension of the use of the cement until the corrections necessary have been taken to ensure that the material meets the specifications. The Contractor shall provide suitable means for storing and protecting the cement against dampness. Cement that has become partially set or that contains lumps of caked cement shall not be used. Cement salvaged from discarded or used bags shall not be used.

701.02Fly Ash

Preapproval shall include submission of a report from the supplier documenting the results of testing the fly ash from that source per the Toxicity Characteristic Leaching Procedure (TCLP) described in 40 CFR 261, Appendix II. The report shall include the results of TCLP testing for

701.03 heavy metals and other contaminants found in the fly ash. The report shall list the contaminants tested, and the allowable levels for each contaminant tested. A new report shall be submitted for each preapproved source annually. Additional TCLP testing may be required when the Department suspects that the fly ash source may have been contaminated. The fly ash shall be subject to sampling and testing by the Department. Test results that do not meet the physical and chemical requirements may result in the suspension of the use of fly ash until the corrections necessary have been taken to ensure that the material meets the specifications.

701.03Silica Fume. Silica fume for concrete shall conform to the requirements of ASTM

C1240.

Silica Fume shall be from a preapproved source listed on the Department’s Approved Products List.

The silica fume shall be subject to sampling and testing by the Department. Test results that do not meet the physical and chemical requirements may result in the suspension of the use of the silica fume until the corrections necessary have been taken to ensure that the material meets the specifications.

701.04High-Reactivity Pozzolans. High-Reactivity Pozzolans (HRP) shall conform to the

requirements of AASHTO M 321. HRPs include but are not limited to metakaolin, rice hull ash, zirconium fume, ultra-fine fly ash, and fume from the production of 50 percent ferrosilicon (with SiO2 less than 85 percent). HRPs shall meet the following optional requirement of AASHTO M 321: The sulfate expansion at 14 days shall not exceed 0.045 percent. HRP shall be from a preapproved source listed on the Department’s Approved Products List. The HRP shall be subject to sampling and testing by the Department. Test results that do not meet the physical and chemical requirements may result in the suspension of the use of HRP until the necessary corrections have been taken to ensure that the material conforms to the specifications.

701.05Slag Cement. Slag cement shall conform to the requirements of ASTM C989. Slag

cement shall be Grade 100 or Grade 120. Slag cement shall have a maximum Aluminum Oxide content of 11.0 percent.

Slag cement shall be from a pre-approved source listed on the Department’s Approved Products List.

Slag Cement shall be subject to sampling and testing by the Department. Test results that do not meet the physical and chemical requirements may result in the suspension of the use of Slag Cement until the necessary corrections have been taken to ensure that the material conforms to the specifications.

701.06Rapid Hardening Cement. Rapid hardening cement shall meet the requirements of

ASTM C1600. ASTM C1600 cements shall have an expansion of 0.05% or less at 6 months or 0.10% or less at 12 months in accordance with ASTM C1012. Rapid hardening cement shall only be used when specified.

Rapid hardening cement shall be from a preapproved source listed on the Department’s Approved Products List
