A forming system and methods that can more efficiently, safely, and economically produce pre-cast modular blocks having desired shapes and surfaces, such as those having reverse tapered shapes. The forming system and methods disclosed herein allow for quick, easy, and efficient demolding and reinstalling of inserts for the production of reverse tapered pre-cast modular blocks.

A kit for forming a monument includes a backplate having a top surface, a plurality of tiles that each have a face with a raised symbol on the face configured to be positioned selectively on the top surface of the backplate, and a perimeter frame sized to mate with the backplate to form a cavity. The tiles can be located in positions on the top surface of the backplate, the perimeter frame can be affixed to the backplate, and a moldable material can be flowed into the cavity where the moldable material can harden. The perimeter frame, backplate and tiles can then be removed from the hardened moldable material, leaving a hardened material with a surface having a recess formed by the raised symbol.

The present invention provides structure protection sheets which can not only dramatically reduce a construction period to place protective layers on surfaces of structures such as concrete but also protect structures for a long time. The present invention relates to a structure protection sheet, including: a polymer cement layer on a side facing a structure; and a resin layer on the polymer cement layer, the structure protection sheet having a thickness distribution of not more than ±100 μm.

In order to enable stable provision of an upward release tube-type ceramic filter used in a molten metal bath and having a side wall with a height of 300 mm or greater, this method for manufacturing a ceramic filter, which is an upward release tube-type integrally molded article for removing unwanted substances from molten metal, has: a step for kneading a mixture of an aggregate comprising ceramic particles, a prescribed binding agent, and water to prepare a base material; a step for integrally forming an upward release tube-type ceramic filter precursor from the prepared base material; step for drying the precursor; a step for providing a retainer for the dried precursor for supporting a side wall of the precursor; a step for subsequently sintering the precursor; and a step for removing the retainer after sintering.

A method for preparation of a mold (10) intended to form a slab from a mixture of agglomerate comprising the steps of depositing over the mold surfaces a sheet (15) of PVA-based plastic material so as to form with it a surface for subsequent contact with the mixture introduced into the mold for forming the slab, whereby in at least some areas a layer (14) of a fluid agent containing PVA in a solution is interposed between the sheet (15) and the mold surfaces. A plant for carrying out the method and a method for production of a slab are also described.

In summary, the invention concerns a mold frame for the production of molded pieces, comprising: at least one mold cavity, the at least one mold cavity being defined by a plurality of mold walls, wherein at least one mold wall of the mold cavity is a mold wall that is displaceably attached to the mold frame.

The invention relates to a moulded part of a composite material comprising a main body (10) of polymer concrete or of reaction resin, which has at least one adhesion bonding surface (11) for adhesively bonding to an article, wherein the adhesive bonding surface (11) is detachably connected to a laminate layer (12) texturing the adhesive bonding surface (11).

The invention comprises a concrete form. The form comprises a first concrete forming panel having a first primary surface adapted for forming and contacting plastic concrete and a second primary surface opposite the first primary surface; a layer of insulating material contacting and substantially covering the second primary surface of the first concrete forming panel; and an insulating blanket adjacent the first concrete forming panel. A method of using the concrete form is also disclosed.

A poured material forming system, including a thin polymer liner for receiving a poured material for forming a wall upon curing of the poured material, the liner containing a texture to be transferred onto the cured poured material. The poured material forming system including a support material positioned opposite the poured material during curing of the poured material for preventing deformation of the liner.
