Sulfate Resistance of Hydraulic Cements Containing Blast-Furnace Slag.
Abstract
As part of one US Army Corps of Engineers research program and one American Society for Testing and Materials (ASTM) cooperative program performed in the Concrete Technology Division of the Structures Laboratory of the US Army Engineer Waterways Experiment Station in the 1970's, five portland blast-furnace slag cements were tested for sulfate resistance. The major intent of this program was to develop a new standardized test for determining sulfate resistance that would be more applicable for testing blended cements than ASTM C 452. The test now exists; it is ASTM C 1012-84. That work included characterization of materials, periodic expansion measurements, periodic determinations of relative modulus of elasticity. Periodic chemical analysis of test solutions, and examination of the paste portion of mortar bars by x-ray diffraction after expansion testing. This report concentrates on expansion results, posttest examination by XRD, and materials characteristics.
