Described herein is a composition for use in a geosynthetic clay liner, the composition comprising particles, at least some of which are discrete particles and each comprise: a compacted swelling clay, the clay having been compacted such that it at least partially surrounds a fluid-loss preventing polymer. Also described herein is a clay liner formed from the composition, a method for producing particles for use in a geosynthetic clay liner, and a method of forming a clay liner.

The present invention relates to a compact and highly dense engineered concrete binder composition and a method of producing the same. In particular, the engineered concrete binder composition comprises at least one mechano-chemically modified component.

[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.
