The invention relates to a method for producing a hydraulically-bonded multilayer panel with at least one face layer and at least one core layer, wherein the method comprises the following steps a. introducing a flowable face mixture into a mold. The face mixture contains at least the following components i. face paste containing at least 1. hydraulic binder and 2. water; and ii. aggregate. The aggregate has a mean diameter d50 determined according to ISO 13320:2009 and/or according to EN 12620 of greater than 100.0 m; whereby a face mixture layer is formed; b. introducing a dry to earth-moist core mixture into the mold, wherein the core mixture contains at least the following components i. core paste containing at least 1. hydraulic binder, 2. fines, wherein the fines have a mean diameter d50 determined according to ISO 13320:2009 of up to 100.0 m, and 3. water; and ii. aggregate, wherein the aggregate has a mean diameter d50 determined according to ISO 13320:2009 and/or according to EN 12620 of greater than 100.0 m; whereby a core mixture layer is formed, and c. pressing the face mixture layer with the core mixture layer into the mold to form a hydraulically-bonded, directly strippable multilayer panel with at least one face layer and at least one core layer, wherein water contained in the face mixture layer is partially or completely pressed into the core mixture layer

A low-density, high-strength concrete composition that is lightweight and self-compacting or non-self-compacting, with a low weight-fraction of aggregate to total dry raw materials, and a highly-homogenous distribution of a non-absorptive and closed-cell lightweight aggregate such as glass microspheres or copolymer polymer beads or a combination thereof, and the steps of providing the composition or components. Lightweight concretes formed therefrom have low density, high strength-to-weight ratios, and high R-value. The concrete has strength similar to that ordinarily found in structural lightweight concrete but at a lower density, such as an oven-dried density as low as 40 lbs./cu.ft. Such strength-to-density ratios range approximately from above 30 cu.ft/sq.in. to above 110 cu.ft/sq.in., with a 28-day compressive strength ranging from about 3400 to 8000 psi.

Cementitious materials having high damage tolerance and self-sensing ability are described herein. These materials may replace conventional concrete to serve as a major material component for infrastructure systems with greatly improved resistance to cracking, reinforcement corrosion, and other common deterioration mechanisms under service conditions, and prevents fracture failure under extreme events. These materials can also be used for the repair, retrofitting or rehabilitation of existing concrete structures or infrastructure systems. Furthermore, these materials may offer capacity for distributed and direct sensing of cracking, straining and deterioration with spatially continuous resolution wherever the material is located, without relying on installation of sensors. The present invention relates to multifunctional cementitious structural or infrastructure materials that integrate self-sensing with damage tolerance for improving safety, extending service life, and health monitoring of structures, components, and infrastructure systems.
