高性能水泥复合砂浆薄层(HPFL)是一种新型的无机材料,具有强度高、收缩小、与混凝土粘结性能好等一系列优点;将其与钢筋网结合形成的加固薄层能与被加固的混凝土构件很好地共同工作,且对原构件的尺寸加大很少。《高性能水泥复合砂浆钢筋网加固混凝土结构技术规程》已通过。主要结合一些试验数据、公式和计算实例对上述规程关于复合砂浆钢筋网薄层加固混凝土结构斜截面承载力计算部分进行简要说明。
High performance ferroeement laminate (HPFL) is a new type of inorganic material with a series of advantanges such as high strength, small shrinkage and good bonding properties, etc. The reinforced laminate of HPFL combined with steel-bar mesh can work well with RC member to be strengthened, and minimize the spacing requirement. The standand of“Technical Specification for Strengthening Conctete Structures with High Performance Ferrocement Laminate” has been showed. Combined with some test data,formulae and calculated example,authors simply explain the standand about calculation of diagonal section resistance for strengthening RC structures using high performance' ferrocement laminate(HPFL).
