Abstract: PROBLEM TO BE SOLVED: To attain excellent mechanical strength with excellent reproducibility by dispersing metallic fibers in a matrix composed of a composition, which contains cement, aggregate particles, pozzolan based reaction particles, acicular or flake like particles and a dispersant, and water. SOLUTION: A concrete having >=10 MPa average bonding stress of the metallic fiber is obtained by adding and dispersing =2 mm fiber length and L/D of >=20 into the cement composition containing 100 pts.wt. cement such as Portland cement, 20-60 wt.% aggregate particles such as silica sand having

Abstract: PROBLEM TO BE SOLVED: To provide an improved type method for spraying concrete or mortar by a dry process or a wet process in order to apply a concrete or mortar layer to a surface. SOLUTION: Just before a spraying means or at a spot of the spraying means, aqueous suspension (A) of aluminum compound selected from silica and aluminum, basic aluminum sulfate, alum, and their mixture is added. Herein, the aqueous suspension (A) has a pH

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: 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: The invention concerns a concrete obtained by mixing with water, cement, granular elements, elements with puzzolanic reaction, constituents capable of improving the toughness of the matrix, metal fibers and at least a dispersing agent, in specified conditions and proportions. Said concrete has improved properties compared to prior art concrete comprising metal fibers.
