Nov 30 2018 · For unexposed specimens the inclusion of lower content of activation leads to an identical result for ambient and hydrothermal curing methods which is higher than watercured samples Increasing the Na 2 O concentration more than 4 results in slightly low bending strength for hydrothermal treatment compared to the two other methods
May 26 2011 · The technological operation of the preliminary simultaneous activation of a filler for artificial building conglomerates and tempering the water by electrodischarge action on sandy slime a suspension of quartz sand is discussed It is shown that there is a physical and chemical activation of quartz sand at the electrodischarge treatment of sandy slime
The influence of grinding the initial quartz sand on the degree of activation of the sandgrain surface during processing using a fluorinating reagent has been studied the curing rate of
The curing regime had a great influence on synthesis as well as the properties of alkali activated material using red mud Unlike high temperature curing under atmospheric pressure autoclave curing made it possible to dissolve more SiO 2 in red mud The solubility of the oxides as well as the properties of the alkali activated material using red mud was significantly improved by increasing curing pressure dwell time and concentration of NaOH solution
Finally the aggregates including quartz sand IBA in the surface dry condition prepared above and 2 steel fibers by volume were added and mixed for 2 min at high speed and 1 min at low speed After that the fresh mixture was cast into the steel molds and vibrated on a vibration table for 1 min
