Abstract

1438745 Cement-resin compositions DEUTSCHE TEXACO AG 22 Oct 1974 [25 Oct 1973 (2)] 45708/74 Heading C1H [Also in Division C3] Moulded shapes are produced by mixing cement into a paste with an aqueous or alcoholic solution of an acetone-formaldehyde resin and curing the paste in a mould at at least 30‹ C. The resin can be produced by condensing acetone and formaldehyde under alkaline conditions at 20-100‹ C. in a ratio between 1 : 1À5 and 1 : 5. 10-100 parts (based on the weight of the resin solids) of a 30-60 wt. per cent solution of the resin can be used per 100 parts of cement. The mix can also comprise sand, gravel and 20- 200 parts of wood chips per 100 parts of cement and can be cured at 30-200‹ C. and up to 180 atmospheres. The mixes used in the examples can comprise sand, wood chips or urea-formaldehyde resin solution in addition to Portland cement and acetone-formaldehyde resin dissolved in water, isopropanol or methanol.
