The present disclosure relates to a ceramic tile decorated with dry particles to give a three-dimensional pattern and a manufacturing method thereof. The manufacturing method comprises the steps of A: glazing a surface of a green body with a ground coat; B: decorating a surface of the ground coat of the green body to form a pattern; C: drying the green body; D: embellishing the green body with dry particles; E: spraying a protective glaze on the surface of the green body; and F: firing the green body after the green body is sprayed with the protective glaze of step E to produce the ceramic tile decorated with dry particles. The manufacturing method can make the ceramic tile produced have a clear pattern, distinct layers, low glaze glossiness, a good non-slip effect, an obvious sense of dry particles, a strong three-dimensional effect, rich colors, and stable properties.

Disclosed are a marine ecological engineering construction method, an asphalt cement-based coating, and a preparation method thereof. The asphalt cement-based coating can make discarded concrete have the capacity of inducing the settlement of sessile organisms, achieve the purpose of using discarded concrete to construct ecological engineering, and has the characteristics of discarded object recycling and marine ecological restoration.

Ceramic tile having a ceramic base layer and a cover glaze layer including a printed pattern, where the surface of the ceramic tile has a relief having structural features corresponding to the printed pattern. The relief being basically formed as a plurality of excavations present in the generally plane upper surface of the ceramic tile and the structural features have a depth such that they are completely situated above the ceramic base layer.

Disclosed is a CO.sub.2 solidified fiber cement board and its preparation method. The matrix composition of the fiber cement board prepared in this disclosure is calcium carbonate, which has high compactness, and the crystal form of calcium carbonate is adjusted by adding shell powder to improve the toughness of the matrix, so that the fiber cement board has excellent mechanics and durability performance. In addition, the preparation process does not require high temperature maintenance, and has the characteristics of normal temperature preparation, which creates conditions for the introduction of organic synthetic fibers, so that the organic synthetic fibers can further improve the brittleness of cement fiberboard. While reducing energy consumption, the preparation process can also effectively solve the problem that excessive pressure is easily generated in the fiberboard under high temperature conditions in the existing high-temperature and high-pressure curing process.
