Patent number: 9676673Abstract: The invention provides a process for the bio-based reparation of a concrete element having an element surface with cavities, comprising applying a first liquid with a first composition and a second liquid with a second composition to the element surface of the concrete element to provide a combined product to the cavities, wherein the first composition and the second composition are selected to provide gel formation in the cavities after application of one or more of the first liquid and the second liquid to the element surface, wherein the first composition and the second composition are also selected to provide bacterial material, a calcium source, and a nutrient for bacteria in the cavities after application of the first liquid and the second liquid to the element surface, wherein the first liquid at least comprises sodium silicate and wherein the second liquid at least comprises the calcium source.Type: GrantFiled: May 16, 2014Date of Patent: June 13, 2017Assignees: Technische Universiteit Delft, Stitchting Voor De Technische WetenschappenInventors: Virginie Aline Christiane Wiktor, Hendrik Marius Jonkers

Publication number: 20160347658Abstract: The invention provides a process for the production of a cementious material. The process comprises mixing cement starting materials and a particulate healing agent to provide the cementious material. The healing agent comprises coated particles, wherein the coated particles comprise bacterial material and additive. The bacterial material is selected from the group consisting of a bacterium, a lyophilized bacterium and a bacterial spore of a bacterium. The present invention solves these problems, as (substantially leakage-proof) tablets containing the actual healing agent may neither interfere with either the workability of the liquid mixture (“cementious material”) nor negatively affect properties of either mixture or final material (hardened concrete), even when applied in large quantities. During crack formation in cementious based constructions, the particles also crack, and healing agent is released.Type: ApplicationFiled: November 14, 2014Publication date: December 1, 2016Applicant: Technische Universiteit DelftInventor: Hendrik Marius JONKERS
