AbstractAbout the AuthorReferences
Replacement of old obsolete presses at silicate factories for foreign equipment intended for the use of sand mixes of a rational composition on the one hand, and diversity of sands used by silicate factories from the other hand, raise the problem of the possibility to simplify the preparation technology of a binder and transfer to the use of clear ready fine lime for producing the silicate brick. The study of effect of sand fineness on the selection of a lime binder type was conducted. The clear lime binder and ground lime with addition of sand – a lime-silica binder (LSB) were considered. Results of raw, autoclaved strength and density of pressed samples of mixes prepared with sands of 0.1–2.6 fineness modulus with the clear lime of 70 and 80% of activity comparing with the samples of the mix with the lime-silica binder are presented. The proposed conclusions give recommendations on priority when selecting the binder depending on the sand fineness.
