A method produces a part of a building. The part of a building has at least one first region and one second region, which adjoins the first region. In the first region, an installation structure is concealed by building material. The method includes the following steps: a) dispensing building material to produce the first region and providing the building material with a marking substance before, at the same time as, and/or after the dispensing operation, and b) dispensing building material to produce the second region.

A method for manufacturing cladding elements for use in construction, including a composite cement-based structure, including an elastically deformable support element having a first surface, a second surface and a plurality of spacer elements having an elongated shape positioned between the first and second surface to realize a plurality of interconnected cavities. The method further provides preparing a substantially fluid and water-based cementitious composition and introducing the substantially fluid cementitious composition into the support element to obtain a composite structure in a deformable state. After this, part of the fluid cementitious composition is removed from the support element, to eliminate the excess fluid cementitious composition and position the deformable composite structure in a forming device. The method provides for maintaining the deformable composite structure in association with the forming device, until the consolidation thereof and that said support element is constituted by a three-dimensional elastically deformable fabric.

A method and an apparatus for producing a concrete component, comprising concrete and a textile reinforcement composed of a reinforcement fiber strand (28), wherein first a yarn (20) is saturated with a mineral suspension (35) and forms the at least one reinforcement fiber strand (28). According to the invention, the reinforcement fiber strand (28) is fed by means of a moving device, so that the reinforcement fiber strand (28) is placed in a concrete strand (4), placed on a concrete layer (2), or placed on a vertical side surface of a plurality of concrete layers placed on top of each other, so that a perpendicular reinforcement is produced when arranged on the outside, and wherein the reinforcement fiber strand (28) is further enclosed by the concrete immediately upon placement or subsequently before the mineral suspension (35) has cured. The invention also relates to a reinforced concrete component (1).

In an exemplary embodiment, a system for forming a flexible mat having an open mesh embedded in and interconnecting a plurality of blocks of a hardened paste includes a rotating drum having a plurality of mold cavities about an outer periphery thereof that receive a hardenable paste; a sheet of the open mesh that is fed over the mold cavities so that the mesh is embedded in the hardenable paste deposited in the mold cavities; and a flexible sheet that is placed against the outer periphery of the drum over the mold cavities containing the hardenable paste and the sheet of open mesh of the rotating drum to retain the hardenable paste within the mold cavities and retain the open mesh embedded in the hardenable paste as the hardenable paste solidifies to form the flexible mat.

A method of manufacturing a tower structure includes providing an additive printing device having at least one printer head atop a support surface. The method also includes positioning a pre-fabricated component adjacent to the support surface. The pre-fabricated component is constructed of a composite material reinforced with a plurality of reinforcement members. Further, portions of the plurality of reinforcement members protrude from the composite material. Moreover, the method includes printing and depositing, via the at least one printer head, a cementitious material onto the support surface to build up the tower structure layer by layer around the pre-fabricated component. Thus, the portions of the plurality of reinforcement members that protrude from the composite material reinforce the cementitious material around the pre-fabricated component.

Concrete can be one of the most durable building materials where consumption is projected to reach approximately 40 billion tons in 2017 alone. Despite this the testing of concrete at all stages of its life cycle is still in its infancy although testing for corrosion is well established. Further many of the tests today are time consuming, expensive, and provide results only after it has been poured and set. Accordingly, by exploiting self-contained wireless sensor devices, which are deployed with the wet concrete, the in-situ curing and maturity measurement data can be established and employed together with batch specific concrete data to provide rapid initial tests and evolving performance data regarding the concrete cure, performance, corrosion of concrete at different points in its life cycle. Such sensors remove subjectivity, allow for rapid assessment, are integrable to the construction process, and provided full life cycle assessment.

A heater includes a plate-shaped part, one or more resistance heating element, a columnar part, and a plurality of relay conductors. The plate-shaped part has an insulation property and includes an upper surface on which a wafer is to be superimposed and a lower surface on an opposite side to the upper surface. The one or more resistance heating element is buried in the plate-shaped part. The columnar part has an insulation property and projects downward from the lower surface of the plate-shaped part. The plurality of relay conductors respectively include extension portions vertically extending inside the columnar part and are electrically connected to the one or more resistance heating elements.

Precast utility enclosure aprons for buried utility enclosures that have an angled top surface to direct water, ice and debris away from the center of the apron and to limit damage to the apron and utility enclosure caused by impacts to the apron.

A precast concrete panel and method for forming the panel are disclosed. A method of forming the panel to be used as a floor, wall, or roof structure includes positioning one or more forming members within a casting bed having a plurality of upright surfaces defining a generally rectangular interior area, the one or more forming members comprising an insulating material extending along a length dimension of the one or more forming members to define a plurality of rectangular-shaped channels in a parallel and spaced-apart relationship, placing uncured concrete within the casting bed and allowing the concrete to cover the one or more forming members and substantially fill the channels, and allowing the concrete to cure.
