硫铝酸盐和铁铝酸盐水泥是中国建筑材料科学研究院发明的水泥系列新品种。它们的主要特点是早强、高强、高抗渗、耐腐蚀和低碱性等。用硫铝和铁铝酸盐水泥配制的高强混凝土,早期强度高、弹性模量高、徐变低和负温强度高,3d 龄期的技术性能已相当或超过了硅酸盐水泥混凝土28d 龄期的技术性能,不仅缩短了混凝土的养护时间,取消蒸汽养护,为快速施加预应力,加快施工
Sulfoaluminates and ferroaluminate cements are new series of cement products invented by the China Academy of Building Materials Science. Their main features are early strength, high strength, high permeability, corrosion resistance and low alkalinity. High-strength concrete formulated with sulphoaluminum and ferroaluminate cements has high early strength, high elastic modulus, low creep and high negative temperature strength. The technical performance at 3 days is comparable to or exceeds 28 days of portland cement concrete. The technical performance of the period not only shortens the curing time of concrete, but also eliminates the need for steam curing, so as to rapidly apply prestressing and accelerate construction.
