Le matériau de produit de construction comprend 60 à 95 % en poids de boue telle qu'une boue aqueuse, une boue d'épuration, une boue aqueuse d'épuration, une boue sédimentaire ou similaire, 10 à 90 % en poids d'une poudre minérale ayant une composition élémentaire de 5 à 81,7 % de C, 20 à 86,7 % de O, 1 à 67,7 % de Mg, 1 à 67,7 % d'Al, 3 à 69,7 % de Si, 0,5 à 67,2 % de S, 0,5 à 67,2 % de Cl, 2 à 68,7 % de Ca, 0,1 à 66,8 % de Ti, 0,05 à 66,75 % de Mn, 0,05 à 66,75 % de Fe et 0,1 à 66,8 % d'In, et 5 à 40 % en poids d'un liant consistant en 10 à 90 % en poids d'un liant liquide obtenu par mélange d'un ou plusieurs composés choisis dans un groupe constitué par un chlorure de métal alcalin et un chlorure de métal alcalino-terreux avec de l'eau agrégée pour obtenir une solution dans laquelle un métal alcalin et/ou un métal alcalino-terreux est élué, et incorporation dans la solution d'eau contenant une faible quantité d'éléments des terres rares et un agent d'ajustement de pH. Le procédé de production d'un matériau de produit de construction comprend les étapes consistant à : se procurer la boue et le liant ; mélanger la boue et le liant ; injecter le mélange de la boue et du liant dans un moule ; appliquer une vibration au moule, injecter le mélange de la boue et du liant à nouveau, et mouler à la presse le mélange ; et retirer le moule et faire durcir naturellement le mélange pressé pour solidifier le mélange. La présente invention permet d'améliorer la force de liaison par la dissolution des substances inorganiques de la boue et des substances inorganiques du liant → la formation d'aquasols → la condensation → la formation de gel → et la cristallisation, ce qui produit un matériau de produit de construction ayant une résistance supérieure à un niveau de résistance prédéterminé, et de prévenir les problèmes provoqués par l'utilisation du ciment. La présente invention met en œuvre le liant constitué uniquement par des substances inorganiques, empêchant ainsi la décharge de contaminants dans l'environnement. En outre, des métaux lourds ou contaminants contenus dans la boue sont fortement liés pour empêcher une contamination secondaire, et le procédé de durcissement naturel de la présente invention permet à des matériaux de produit de construction d'être produits de façon économiquement avantageuse et simple.
