The present invention relates to methods for the production of fresh cured fiber cement products. More particularly, the present invention provides methods for the production of fresh fiber cement products comprising cured fiber cement waste material, at least comprising the steps of: (a) Providing a cured fiber cement waste powder by comminuting cured fiber cement waste material; (b) Providing an aqueous fiber cement slurry comprising water, cementitious binder, natural or synthetic fibers and said cured fiber cement waste powder; (c) Forming a green fiber cement sheet from said aqueous fiber cement slurry; and (d) Autoclave-curing said green fiber cement sheet thereby providing a fresh fiber cement product.

There is provided at least any of a layered body which has a change in color tone and in which it is unnecessary to select a colorant and the content of the colorant in consideration of a difference in the sintering behavior between layers, a precursor thereof, or a method for producing these. Provided is a layered body which has a structure, in which two or more layers containing stabilizer-containing zirconia and a colorant are layered, and in which types and contents of the colorants contained in the layers are equal to each other, the layered body including at least: a first layer containing a colorant and zirconia which has a stabilizer content of higher than or equal to 3.3 mol %; and a second layer containing a colorant and zirconia which has a stabilizer content different from that of the zirconia contained in the first layer.

Provided are a textile reinforced cement composite for suppressing occurrence of slipping and a crack and a manufacturing method thereof. The textile reinforced cement composite for suppressing occurrence of slipping and a crack can suppress slipping between a textile grid reinforcement and a cement composite by using an angulated filling material mixed therewith when a textile reinforced cement composite having a textile grid reinforcement embedded in a cement composite is manufactured, suppress occurrence of a crack of the cement composite, suppress occurrence of a crack of the cement composite due to a fiber bridging reaction by using organic fiber mixed therewith, induce distribution of fine cracks, suppress degradation of fluidity of the cement composite caused by mixing of the angulated filling material by using a spherical binder and a chemical admixture added thereto, and suppress slipping between the textile grid reinforcement and the cement composite by using a fine powder binder having a predetermined particle size and mixed therewith.

A concrete product set by pouring a concrete slurry includes a) a concrete mixture; b) a graphene admixture; c) a colloidal silica admixture; and d) at least one reinforcing fiber selected from the group of fibers. As the poured concrete slurry cures, the poured slurry hardens into a composite material product, and the composite material defines capillary structures that at least in part fill with silica and lime, and the surrounding composite material is embedded with graphene. In another exemplary embodiment, the present invention is directed to a process for preparing a concrete product. The process comprises the steps of a) preparing a concrete slurry; b) pouring the concrete slurry; and c) allowing the concrete slurry to cure. In another exemplary embodiment, the present invention is directed to the product itself; namely, a concrete product with or without fibers, or to the admixture(s).
