发展粉煤灰硅酸盐大型墙板是实现建筑业工业化的重要途径之一。将工业废渣粉煤灰、电石渣、炉渣等转化为有用的建筑材料,也是保护环境卫生造福人民的重大措施。当前,发展和推广使用粉煤灰硅酸盐墙板所急待解决的一个课题,便是如何阻止墙板中钢筋的锈蚀,以及在采取防护措施后钢筋和混凝土间粘结力是否能满足设计要求。我们针对以上课题作了一些试验和探讨,初步得出在粉煤灰硅酸盐混凝土中掺加1％和2％的工业亚硝酸钠阻锈效果良好,而其粘结力也完全满足钢筋混凝土的设计规范的要求。
The development of fly ash silicate large wall panels is one of the important ways to achieve the industrialization of the construction industry. The conversion of industrial waste fly ash, carbide slag, slag, etc. into useful building materials is also a major measure to protect environmental health and benefit people. At present, one of the urgent issues to be solved in the development and promotion of the use of fly ash silicate wallboard is how to prevent the corrosion of the steel bars in the wallboard and whether the adhesion between the reinforcement and the concrete can meet the design after protective measures are taken. Claim. We have conducted some experiments and discussions on the above issues. We have initially concluded that the addition of 1% and 2% of industrial sodium nitrite in fly ash-silicate concrete results in good rust resistance, and its cohesion also fully meets the requirements of reinforced concrete. Design specification requirements.
