本文在充分分析本领域国内外研究现状的基础上，首先通过引入添加剂钛酸镁( m2t ) ，使其与钛酸铝形成固溶体，以达到抑制钛酸铝中温分解的目的；再通过与强度高、气密性好的氧化铝进行梯度复合来提高整体材料的强度并能弥补钛酸铝渗透性能差，同时对材料的低热膨胀性能影响不大。 |
| 10. | From the research on hpec we can know that expansion property of high strength superplasticized expansive concrete shows obvious particularity compared with ordinary expansive concrete . when bfs is not put in , high strength superplasticized expansive concrete shows autogenous shrinkage in 1 day standard curing . and in 14 day ' s age e2 is less than half of middle strength superplasticized expansive concrete ' s with same csa dosage , and this shows expansion effect is confined more
对hpec混凝土的研究发现，与普通膨胀混凝土相比，高强流态膨胀混凝土的膨胀性能表现出明显的特殊性，在不掺超细矿物质掺合料(磨细矿渣)时，高强流态膨胀混凝土标准养护1天时出现自收缩， 14天时其限制膨胀率不到相同csa掺量的中强流态膨胀混凝土限制膨胀率的一半，表现为膨胀效应受到更大限制。 |
