Abstract:
This specification covers hydraulic cements that expand during the early hardening period after setting. The cement covered by this specification is suitable for use in shrinkage-compensating concrete and shall be designated as Type E-1. Expansive cement shall conform to the requirements as to chemical composition prescribed. Expansive cement shall conform to the physical requirements prescribed. The cement shall be sampled and the properties shall be determined with the following test methods: sampling, chemical analysis, time of setting, air content, restrained expansion of mortar, compressive strength, and density.
