Experiment Research to Improvement the Soundness of Cementitious Material Blended with Cycled Fluidized Bed Ash
This paper presents experimental results on the expansion by Le chaterlier tester and the compressive strength. Hydraulic ash-zeolite (HAZ) cementitious material was blended as the chemical activator to study the effects of the activator on the soundness. The results show that HAZ can not only deduce the expansion, but it can also make the prisms compressive strength increased obviously. FT-IR apectroscopic and X-ray diffraction analysis indicated that the main hydrated products of the sample are calcium hydroxide, ettringite, zeolite and calcite, which consistented with the results of the expansion and the strength tests.
