  11. We research the causes of concrete cracking, develop the high performance anti - cracking additive, optimize the concrete mix and construction techniques, increase the stability of concrete volume by shrinkage compensation, enhance splitting tensile strength, and can meet demand of high workability of fresh concrete. in the study, a thorough investigation of this problem is made from all points of view, with the aid of various modern measurement & testing technology and different theories & methods in surface physical chemistry, structural chemistry, solid - state chemistry, composite materials, fracture mechanics, etc. our research results have shown that the various shrinkage of concrete cause concrete cracking in building engineering, such as autogenous shrinkage, dry shrinkage, temperature shrinkage, plastic shrinkage, carbonized shrinkage, etc

    目前，解決混凝土開裂的方法是綜合的，我們調查研究了混凝土開裂的原因，開發研製了高性能抗裂外加劑，優化混凝土的設計和施工方法，並通過補償收縮達到混凝土體積穩定，提高抗裂強度，滿足混凝土拌和物高工作性能的要求。本研究採用多種測試技術，應用表面物理化學、結構化學、固體化學、復合材料學、斷裂力學等多學科的理論與方法，從不同的角度進行深入的研究和探討。通過調查研究建築工程中出現的混凝土開裂、滲漏問題，發現混凝土在非荷載作用下開裂主要是由混凝土的自收縮、乾燥收縮、溫度收縮、塑性收縮、碳化收縮等各種收縮變形引起的。
  12. 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

    對hpec混凝土的研究發現，與普通膨脹混凝土相比，高強流態膨脹混凝土的膨脹性能表現出明顯的特殊性，在不摻超細礦物質摻合料（磨細礦渣）時，高強流態膨脹混凝土標準養護1天時出現自收縮， 14天時其限制膨脹率不到相同csa摻量的中強流態膨脹混凝土限制膨脹率的一半，表現為膨脹效應受到更大限制。
