Utilization of industrial wastes for mortar

摘要

The paper describes a study undertaken to examine the use technogenic wastes in mortar mixes. It was developed the rules about elimination of inhomogeneityes of technogenic wastes & creation of organic-mineralic additives (OMA), consisting from mineral fillers & surface-active sustance (SAS) on a basis of an industrial wastes subjected of mechanic-chemical activation. The results showed a reduction water consumption below on 15-40 dm~3/m~3 in the mortar with OMA. the workability tests showe dthat mortar modified OMA, have increased in comparison with cement mortar water-keeping ability growing with increase of the contents OMA. The size of relative increase of water-keeping ability for mortar with OMA on limestone filler has made 10-65
