Next was an experimental study on modification of stone ballast concrete small hollow block. the influence of polypropylene fiber, expansion agent and both of them on permeability - resistance and both moisture expansion and dry shrinkage of the block were systematically tested. the testing results and theoretical analysis slowed that they all can improve its properties, among which polypropylene fiber can most effectively restrain it ’ s moisture expansion and drying shrinkage ; however, the block doubly blended with polypropylene fiber and expansion agent will be likely to most beneficially improve crack - resistance of wall filled with the block
試驗結果和理論分析表明，單摻聚丙烯纖維、單摻膨脹劑和雙摻聚丙烯纖維與膨脹劑均能改善混凝土空心砌塊的性能，其中，聚丙烯纖維更有利於限制單個砌塊的濕漲干縮，單摻聚丙烯纖維的空心砌塊濕脹干縮的波動性最小;雙摻聚丙烯纖維與膨脹劑對限制石渣砌塊濕脹干縮的效果不理想，但雙摻砌塊將更有利增強于砌塊填充墻的整體抗裂性。 -
