Various embodiments of the present disclosure provide a load transfer plate including a non-symmetrically shaped body having a semi-cylindrical first portion configured to protrude into and be secured in the first cast-in-place concrete slab and a non-semi cylindrical second portion configured to protrude into a load transfer plate pocket secured in the second cast-in-place concrete.

A method for making a reinforced concrete structure and reinforcement agents are provided. In some embodiments, the method includes obtaining a mold for the reinforced concrete structure. A lattice is formed within the mold, where the lattice includes inter-locking ringed fibers and where each inter-locking ringed fiber is a fiber formed into a ringed structure that is inter-locked with at least one neighboring inter-locking ringed fiber in the lattice. The lattice is then encased by filling the mold with concrete. In some embodiments, the reinforcement agents are a plurality of ringed fiber-structures, each of which is coiled into a ringed structure that may or may not inter-lock with at least one neighboring ringed fiber(s)-structure.

A dowel placement system including a fastener configured to be engageable with a form, and a radially compressible bushing coupled to the fastener and defining an adjustable outer diameter. The system further includes an elongate dowel sleeve having opposed proximal and distal end portions, and an axial opening having an inner diameter and extending into the dowel sleeve from the proximal end portion to the distal end portion. The bushing is insertable within the axial opening of the dowel sleeve, and the bushing and dowel sleeve are configured such that insertion of the bushing within the dowel sleeve causes the outer diameter of the bushing to compress and conform to the inner diameter of the dowel sleeve and to create a friction force between the bushing and the dowel sleeve to mitigate movement of the dowel sleeve relative to the bushing during formation of the concrete structure.

A curb former (10) includes a rotatable drive shaft (20), a gutter drum (80), and a curb profiling drum (100). The gutter drum (80) is secured to the drive shaft (20) such that the drive shaft (20) and gutter drum (80) rotate together. The curb profiling drum (100) is detachably secured relative to both the drive shaft (20) and the gutter drum (80). This configuration allows one curb profiling drum (100) to be replaced with another curb profiling drum (100) to change the profile of a curb resulting from a curbing operation using the curb former (10).

A cement form assembly includes cement and a cement form. The cement form can include a ground facing surface extending horizontally on a ground support surface and a cement facing surface extending vertically and contacting the cement. An extension member extends outward from the cement form and includes a surface that extends the ground facing surface or the cement facing surface. The cement form and the extension member are each made, at least partially, of a foam material.

A field-assembly dowel basket for concrete construction configured for in-the-field assembly from standardized components. This allows a number of standard components, including clips, connectors and wire frame components, to be conveniently transported and stored on construction sites to facilitate on-site assembly of dowel baskets on an as-needed, where-needed basis. Since the dowel basket components are much smaller than assembled baskets, they can be shipped and stored much more cost effectively. Standardization of components allows mass production, consolidates inventory management, and avoids the need for ad hoc fabrication for each construction site. On-site fabrication largely eliminates welding from the dowel basket fabrication process (wire frame clips may involve welding), avoids shipping of fabricated dowel baskets, and allows assembly of dowel basket by construction workers as opposed to highly skilled welding shops.
