NCC Task Force on C595 and C1157 Cements

The NCC Task Force on C595 and C1175 Cements was initiated in order to develop an electronic forum for documenting and exchanging information about the performance characteristics of ASTM C595 / AASHTO M240 and ASTM C1175 cements in concrete for paving and transportation structures.


  • The objectives of the NCC Cement Task Force are to:
  • Establish an electronic resource (website) to
  • Share state experience with projects that have used ASTM C595/AASHTO M240 and ASTM C1157 cement specifications
  • Share testing and project data from cement manufacturers and other laboratories
  • Post or link to relevant research
  • Develop and post Frequently Asked Questions
  • Identify technology transfer needs and meet those needs
  • Report to NCC on task force activities and recommendations
