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: 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.

Abstract: Concrete comprises organic fibers dispersed in a hardened cement matrix. Concrete comprising organic fibers dispersed in a hardened cement matrix is obtained by mixing with water composition comprising fibers and: (a) cement; (b) granular components with maximum size, D, of no more than 2 mm, preferably no more than 1 mm; (c) fine components from ash with size no greater than 20 microns preferably no greater than 1 microns ; and (d) at least one dispersing agent; said composition meeting the following conditions: (e) wt. % water with respect to total weight of (a) and (c) = 8-25; (f) organic fibers have individual length, l , of at least 2 mm and ratio l\/ phi ( phi = diameter) at least = 20; (g) ratio, R, of mean length of fibers to D at least = 5; and (h) quantity of fibers is such that their volume represents no more than 8% total volume of concrete. An Independent claim is also included for pre-mixture for preparing cement matrix for making said concrete.
