Various aspects relate to binder compositions including a bio-based component and pre-blends for forming the same. A binder composition includes an oligomerized biorenewable oil that is at least 10 wt % of the binder composition. The binder composition also includes an Asphaltene Additive comprising at least 20 wt % to 100 wt % asphaltenes, wherein the Asphaltene Additive is at least 8 wt % of the binder composition.

A method of pouring a body, including mixing an isocyanate, a polyol, and a catalyst to yield an admixture, dispersing a particulate phase in the admixture to yield a homogeneous composition, pouring the homogeneous composition into a preform, capping the preform to prevent expansion of the homogeneous composition thereoutof, and curing the homogeneous composition to yield a polymeric composite body. The matrix portion is formed from a polymerizable formulation comprising at least one isocyanate precursor, at least one polyol, and a catalyst contained in a mold having a pressure rating of at least 0.4 Mpa. The at least one isocyanate precursor is selected from the group consisting of polymethylene polyphenylisocyanate, diphenylmethane diisocyanate, triphenylmethane triisocyanate, toluene diisocyanate and methyl diisocyanate (MDI), and combinations thereof. The catalyst is selected from the group consisting of a dialkyltin derivative, tributyl bismuth, and combinations thereof and is a tertiary amine.

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.

The present invention relates generally to composite products, in particular glass-based composite products, and the manufacture thereof.

Provided herein are cementitious materials, for example, a crack-resistant cementitious mortar. The cementitious materials are a mixture of cement, at least one recycled fiber reinforcement material, a recycled aggregate material, and water. Also provided is a method for increasing the crack-resistance of a cementitious material by replacing the sand in a cement mortar with a recycled aggregate material and adding at least one recycled fiber reinforcement material and a volume of water.
