    • The present invention relates to a novel additive for hydraulic cements, mortars and concretes, particularly for improving the mechanical strengths and the workability and for reducing sweating and segregation, which is characterized in that it is a protein hydrolysate having a pH less than or equal to 6, comprising substances selected from the group constituted by proteins, polypeptides, aminoacids and mixtures thereof, and obtained by treating 100 volumes of an aqueous composition containing at least one protein substance selected from the group constituted by proteins, polypeptides and mixtures thereof, with at least one bacterial strain producing lactic acid having a population greater than or equal to 10.sup.2 germs/cm.sup.3, in the presence of 0.5 to 30 parts by weight of a source of carbon belonging to the family of carbohydrates, for at least 2 hours, at a temperature of between 0.degree. and 65.degree. C. and at a pH less than or equal to 6.
    • 本发明涉及一种用于水硬性水泥,砂浆和混凝土的新型添加剂,特别是用于改善机械强度和加工性以及减少出汗和偏析,其特征在于它是一种蛋白质水解产物,其pH值小于或等于 6,其包含选自由蛋白质,多肽,氨基酸及其混合物组成的组的物质,并且通过将100体积的含有至少一种选自蛋白质,多肽及其混合物的蛋白质的含水组合物与 在0.5至30重量份属于碳水化合物家族的碳源的存在下,在至少2小时的时间内,生产具有大于或等于102个细胞/ cm 3的种群的乳酸的至少一种细菌菌株 温度在0℃至65℃之间,pH小于或等于6。
