[Object] To provide a building material having excellent durability.

[Solution] A building material has a convex part formed on a surface thereof, the convex part including a first lateral surface part and a second lateral surface part corresponding to the first lateral surface part. The building material is formed from a mixture containing a hydraulic material, an admixture, and a plant-based reinforcing material, and the plant-based reinforcing material at least in the convex part is distributed in the mixture with the hydraulic material and the admixture attached to the plant-based reinforcing material. A distribution of the plant-based reinforcing material in the first lateral surface part and a distribution of the plant-based reinforcing material in the second lateral surface part are substantially the same. Desirably, the convex part includes a first edge part that is an edge part of the first lateral surface part and a second edge part that is an edge part of the second lateral surface part and that corresponds to the first edge part, and a distribution of holes formed in the first edge part and a distribution of holes formed in the second edge part are substantially the same.

Devices and systems for collapsible engagement mechanisms are described herein. In some examples, one or more embodiments include a front panel, a first side panel connected to the front panel, a second side panel connected to the front panel, and a collapsible portion connected to at least one of the first side panel and the second side panel, where the collapsible portion is collapsible about a hinge.

Described is a method of manufacturing a binder and the use of the binder to manufacture a roading mixture through mixing with aggregate, or a composite plastic product through the mixture of binder with particulate matter and/or fibre. The binder comprises mixing a plastic with two or more ethylenically unsaturated monomers in a mixing tank. The two or more ethylenically unsaturated monomers may have different homopolymer glass transition temperatures (TO wherein a first monomer structural unit has a homopolymer T.sub.g of greater than 80° C. and a second monomer having a homopolymer T.sub.g of less than 80° C. The plastic may be selected from a plastic comprising a styrene homopolymer, a styrene copolymer, a copolymer of an alkene and vinyl acetate, acrylic polymer and nylon based polymers or co-polymers, polyester-based thermoplastic polymer resin, propylene-based thermoplastic polymer and homo-polymer of an alkene or combination thereof.
