Abstract

1,262,162. Silicate compositions. FARBWERKE HOECHST A.G. 30 May, 1969, No. 27445/69. Heading C3N. A dry composition for the production of acidresistant cement or mortar compositions comprising an inert filler, a water-soluble solid sodium silicate and a condensed aluminium phosphate having a molar ratio of P 2 O 5 : Al 2 O 3 of from 1À1 : 1 to 3 : 1, which has been obtained from an acid aluminium phosphate having the said molar composition by heating it in a first stage at a temperature not exceeding 400‹ C. until its weight remains constant, and in a second stage at a temperature not exceeding 750‹ C. until its weight remains constant. The inert filler may be quartz sand, quartz meal, coke, graphite powder, titanium dioxide, and heavy spar all of which may have a minor proportion of kaolinitic clay. Both the sodium silicate and the condensed aluminium phosphate may be rendered hydrophobic by treatment with a mineral oil. The composition may also contain an anionic or non-ionic surface-active substance, e.g. ethoxylated polypropylene glycol ethers, preferably in an amount of 0À05-3% by weight, calculated on the total weight of the mixture. The composition preferably comprises 10-30% by weight of solid watersoluble sodium silicate and 3-10% by weight of the condensed aluminium phosphate, calculated on the total weight of the composition, whilst the composition of the water-soluble solid sodium silicates used preferably fall within the range 27-18À5% by weight Na 2 O, 54- 62À5% by weight SiO 2 and 19% H 2 O.
