A hydraulic composition comprises a hydraulic component and an organic hydrogel, and optionally aggregate, a reinforcing material and other additives and has a slump value, determined by the testing method of JIS A1101, of not more than about 1 cm in a concrete formulation and a flow value, determined by the testing method of JIS R5201, of not more than about 120 mm in a mortar or paste formulation.

Hydraulic composition

In a process for producing a coke by carbonization of a starting coal, the improvement wherein a coal containing a bulk density improving agent composed of a high-molecular organic compound capable of forming a hydrous gel in the presence of moisture is used as the starting coal.
