Corrosion of Embedded Materials

Work at the FHWA (Clear 1973) found that the conversion factor from acid-soluble to water-soluble chlorides could range from 0.35 to 0.90, depending on the constituents and history of the concrete. Arbitrarily, 0.75 was chosen, resulting in a water-soluble chloride limit of 0.15 percent by weight of cement.

Performance Enhancer for Portland Limestone Cement (PLC)

An identical concrete mix (cement = 300kg/m 3, w/c = 0.60) was used to produce cubes which were subjected to the freeze-thaw test according to CEN/TS 12390-9. The concrete must have less than 10% loss of weight after 100 cycles to fulfill the requirement of the standard.

Cement Additives

These admixtures increase the productivity of the grinding aid at the same time. Performance Enhancer Clinker is often replaced with supplementary cementitious materials (SCM) such as granulated blast furnace slag, natural pozzolanes and fly ash in order to reduce CO 2 emissions and material cost.
