混凝土配合比设计是混凝土企业技术人员必须掌握的关键技术,设计优良的配合比能为企业提高经济效益,减少质量事故,使企业竞争处于有利地位。然而,由于各地原材料质量差异较大,技术人员水平参差不齐,部分技术人员对相关标准规范领悟不深,对材料之间性能及影响了解不透彻,因此也就造成了相同地区、相同原材料等条件下混凝土性能和成本的差异,有些差异还较大。目前,虽然国家各部门对混凝土质量加大监管力度,但阴阳配合比仍旧盛行,这里面也不能完全说是混凝土企业的问题,也可能是国家制定的相关标准规范没有能与时俱进和与“实”俱进。另外新版《普通混凝土配合比设计规程》已经发行,将在今年年底实施,本期特别策划将就混凝土配合比设计方面的技术、理念及对目前配合比设计相关标准规范的看法邀请多位专家来共同参与探讨。 Concrete mix design is the key technology that must be mastered by technicians in concrete industry. The excellent mix of design can improve the economic benefits and reduce the quality accidents for enterprises, and make the competition of enterprises in a favorable position. However, due to the large differences in the quality of raw materials across the country, the uneven level of technical staff, some of the technical staff to understand the relevant standards and regulations is not deep understanding of the performance and influence between materials is not thorough understanding, thus resulting in the same area, the same raw materials Concrete conditions under the conditions of performance and cost differences, some differences are still larger. At present, though various departments of our country are supervising the quality of concrete, the mix of yin and yang is still prevailing, which can not be completely said to be a problem for concrete enterprises. It may also be that the relevant national standards formulated by the state fail to keep pace with the times and “Real ” both. In addition the new version of “Ordinary concrete mix design rules” has been issued, will be implemented by the end of this year, this special planning will be concrete mix design of the technology, ideas and standards for the current mix of design standards to invite a number of experts to come Participate in discussion.
