Abstract: Concrete or mortar is sprayed onto a surface by adding an aqueous suspension of silica, and an aluminium cpd. selected from aluminium sulphate, basic aluminium sulphate, alkali metal aluminium sulphate or their mixts.. The suspension has a pH of less than 4, and contains 10-50 wt.% dry material. After storing for 48 hrs., it forms a gel which can be converted back into a suspension by mild stirring.

Abstract: The material for injection to shroud a framework, and especially prestressed cables, is composed of 1.3-3.0 wt.% of inert hydrophilic particles in the cement mixture. They have a specific surface of more than 200 m /g, to give a fraction during mixing and/or injection into numerous fragments as small as 5 nanometres and as large as 300 nanometres. The particles are of precipitated silica.

Abstract: A concrete includes organic fibers, dispersed in a cement matrix. The cement matrix includes elements having predetermined particle sizes. The organic fibers have predetermined lengths and diameters. The behavior of the concrete is improved both with respect to the occurrence of minute cracks and the propagation of large cracks as a result of a synergistic effect between the cement matrix and the organic fibers.
