Abstract

The strength of concrete is improved by adding to the concrete mix aluminium powder in an amount less than 0,03 per cent of the dry cement. Specifications 244,671, 244,963, [both in Class 22], and 268,893, [Class 95], are referred to. The Specification as open to inspection under Sect. 91 is not limited to the addition of the aluminium in the proportions specified above and refers to the addition of 0,03-0,3 grams of aluminium powder per pound of cement. This subject-matter does not appear in the Specification as accepted.
