Abstract: Shaped articles made from expanded minerals obtained by treating a mixture of a hydrophobized expanded mineral and a calcium aluminate with an aqueous solution of aluminum phosphate, and subsequently consolidating it under the action of pressure and heat; the expanded mineral having been hydrophobized with a hydrophobizing agent consisting substantially of (a) a fatty amine of the formula in which R1 is C8-C22-alkyl, preferably C14-C22-alkyl, C14-C22-alkenyl or C8-C22-alkylphenyl, R2 and R3 each are hydrogen, C1-C4-alkyl or C2-C4-alkenyl, phenyl or benzyl, and n is a number of from 0 to 4; (b) a fatty acid of the formula R5CO(OCH2CH2)mOH or a fatty alcohol of the formula R6(OCH2CH2)mOH in which R5 is C8-C22-alkyl, preferably C14-C22-alkyl or -alkenyl, R6 is C9-C23-alkyl, preferably C15-C23-alkyl or -alkenyl, and m is a number of from 0 to 2; and (c) a low molecular weight acid.

Abstract: A water-repellent gypsum mortar contains an agent conferring hydrophobic properties, which is composed of (a) a fatty amine of the formula in which R1 is C8-C22-alkyl, C8-C22-alkenyl or C8-C22-alkylphenyl, R2 and R3 are hydrogen, C1-C4-alkyl, C2-C4-alkenyl, C1-C4-alkoxy-C1-C4-alkyl, C1-C4-hydroxyalkyl, phenyl, benzyl or a group of the formula -(CH2CH2O)nH and n is a number from 0 to 4, (b) a low-molecular acid and (c) an alkali metal siliconate.

Abstract: Shaped articles made from expanded minerals, obtained by solidification of a mixture of water glass, catalyst and an expanded mineral pretreated with a hydrophobizing agent which comprises substantially (a) a fatty amine of the formula in which R1 is C8-C22, preferably C14-C22-alkyl or -alkenyl, or C8-C22-alkylphenyl, R2 and R3 each are hydrogen, C1-C4-alkyl or -alkenyl, phenyl or benzyl, and n is a number of from 0 to 4: (b) a fatty acid of the formula R5CO (OCH2CH2)mOH or a fatty alcohol of the formula R6(OCH2CH2)mOH in which formulae R5 is C8-C22, preferably C14-C22-alkyl or -alkenyl, R6 is C9-C23, preferably C15-C23-alkyl or -alkenyl, and m is a number of from 0 to 2; and (c) a low molecular weight acid.

Abstract: Shaped articles made from expanded minerals, otained by using a mineral binder system composed either of calcium aluminate and aluminum phosphate or of waterglass and a catalyst to consolidate an expanded mineral which has been rendered hydrophobic and wherein the expanded mineral is rendered hydrophobic by means of an organosiloxane.
