METHOD OF PREPARING MAKE-UP MEDIUM FOR HIGH-SLUMP CONCRETE MIXES |
摘要 |
In the preparation of high-slump concrete mixes, for preparing a make-up medium, cement is mixed with make-up water in a mass ratio of from 1:1 to 1:1.5; a yeast-sulphite waste liquor in an amount from 0.03% to 0.1% of the mass of cement in the concrete mix is added to the resulting mixture, and after that the make-up medium thus formed is subjected to pulsed vibrations, the frequency of medium pulsations ranging from 600 to 950 Hz. The invention has application in the manufacture of highly reinforced large-size articles and structures. |
