Abstract
The invention provides a process for the production of a cementitious material, comprising mixing cement starting materials, a healing agent and a fibrous reinforcing material, wherein the healing agent comprises bacterial material, and wherein the fibrous reinforcing material comprises a biodegradable polymer, having an average molecular weight selected from the range of 10-1500 kg/mol, and wherein the fibrous material comprises fibers having diameters selected from the range of 5-750 μm, and having lengths selected from the range of 50 μm-150 mm.
Claims17
A process for the production of a cementitious material, comprising mixing cement starting materials, a healing agent and a fibrous reinforcing material, wherein the healing agent comprises bacterial material, wherein the fibrous reinforcing material comprises a biodegradable polymer, having an average molecular weight selected from the range of 10-1500 kg/mol, and wherein the fibrous material comprises fibers having diameters selected from the range of 5-750 μm, and having lengths selected from the range of 50 μm-150 mm.
A cementitous material comprising (a) cement, (b) one of more of slag, ash, limestone and sand, (c) optionally super plastisizer, (d) healing agent, and (e) fibrous reinforcing material, wherein the healing agent comprises bacterial material, wherein the fibrous reinforcing material comprises a biodegradable polymer, having an average molecular weight selected from the range of 10-1500 kg/mol, and wherein the fibrous material comprises fibers having diameters selected from the range of 5-750 μm, and having lengths selected from the range of 50 μm-150 mm, having a weight ratio of healing agent to (a) cement, and (b) one of more of slag, ash, limestone and sand selected from the range of 0.2:100-10:100, and having a weight ratio of fibrous reinforcing material to (a) cement, and (b) one of more of slag, ash, limestone and sand selected from the range of 0.1:100-10:100.
A construction element comprising hardened cementitious material, wherein the cementitious material further comprises bacterial material and one or more of (i) fibrous reinforcing material comprising a biodegradable polymer, and (ii) a conversion product of a bacterial conversion of the fibrous reinforcing material comprises a biodegradable polymer.
