A cell for a stormwater management system includes a body portion, an internal region, and at least one of a top portion or a bottom portion. The body portion includes a plurality of corner columns spaced from each other, a first horizontal member, and a second horizontal member. At least one of the first and second horizontal members is adjacent the at least one of the top portion or the bottom portion and opposite the other horizontal member. The first horizontal member extends between at least two corner columns and has at least a portion curved inward towards the internal region. The second horizontal member extends between at least two corner columns and has at least a portion curved inward towards the internal region. The first and second horizontal members are integrally formed with the body portion.

The present invention relates to a composite floor, typically a wood/concrete composite floor. The composite floor comprises a support structure being adapted to be attached to a concrete layer. The support structure comprises a top portion being made of at least one support panel comprising at least one opening through which the concrete layer may flow into the inner portion of the support structure once the top portion of the support structure is being disposed on the top of the concrete layer. The upward flow of the concrete creates at least one anchor point, which, once being harden in the inner portion of the support structure, improves the adhesion between the support panels and the concrete and ensures better mechanical rigidity and resistance of the assembly made of the panels and the concrete.

Methods for forming ceramic cores are disclosed. A ceramic core formed using the method of the present application includes a silica depletion zone encapsulating an inner zone. The inner zone includes mullite and the silica depletion zone includes alumina. The method includes heat-treating a ceramic body in a non-oxidizing atmospheric condition for an effective temperature and time combination at a pressure less than 10 atmosphere to form the silica depletion zone at a surface of the ceramic core.

Embodiments of a mold for making a retaining wall blocks are disclosed. The mold enables blocks to be made more quickly by enabling separation of each block from the mold housing when the block is cured sufficiently to enable separation. Once separated, the block can be permitted to fully cure away from the mold housing, while the mold housing is re-used to produce one or more other blocks. In one embodiment, among others, the mold has a movable bottom tray and a mold housing with at least one door. The mold housing has an opening designed to receive and introduce a fabrication material, such as concrete, into the cavity. Once a block is sufficiently cured, it is separated from the mold housing on the tray through the at least one door, and a new tray is inserted in the mold housing to make another block.

A molded concrete U-wall construction block including a molded concrete U-wall construction block structure formed from cured concrete poured about a block cage made from reinforcing material during a block manufacturing process. The block cage includes an open aperture formed in each of its stem reinforcing portions. During the block manufacturing process, the first and second support members of a support mechanism are inserted within the open apertures formed in the stem reinforcing sections of the block cage, and cooperate with the open apertures of the block cage so as to (i) support the block cage when being loaded into a block manufacturing machine, (ii) define central apertures molded in each stem portion of the concrete U-wall construction block structure, and (iii) lift the molded concrete U-wall construction block when being unloaded from the machine.

A system for the automatic release of cast concrete products from flexible and deformable moulds is described. The system has an apparatus configured to supply the moulds and carry out the pre-mould-release of the products contained within such moulds. The apparatus has a first conveyor belt associated with a first pre-mould-release group and a second conveyor belt associated with a second pre-mould-release group. The second conveyor belt is placed downstream of the first conveyor belt and both pre-mould-release groups are configured to facilitate the subsequent mould-release of the products. The system further has a mould-release machine arranged downstream with respect to the first and second conveyor belts. The mould-release machine has a mould-release group, configured to carry out the extraction of the products from the respective moulds, and a plurality of conveyor belts, configured to move the moulds and the products inside the mould-release machine.
