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。 -
After all, there came an experimental study on modification of wall filled with stone ballast block
最後進行石渣砌塊填充墻（模擬）的改性試驗研究。 -
Spot investigating results revealed, subjective factors causing crack in wall filled with stone ballast block can be eliminated by intensifying instruction, strengthening management and strict overseeing
現場調研顯示，引起石渣砌塊填充墻裂縫的主觀因素，可以通過加強指導，強化管理，嚴格監督予以消除。 -
However, it is a key problem that shrinkage of stone ballast block is an internal cause of crack, so the leading idea of remedial works of crack should focus on “ eliminating internal causes ” rather than “ external treatment of crack ”
不過，治理裂縫的主導思想不應局限於「外治」 ，也應著眼于「內消」 。抓住了砌塊的收縮變形這一內因，也就抓住了解決問題的關鍵。 -
The influence of polypropylene fiber, expansion agent and both of them on moisture expansion and dry shrinkage of the filled wall were systematically tested. the testing results and theoretical analysis slowed that polypropylene fiber was the most beneficial to restrain it ’ s moisture expansion and drying shrinkage, however, the block doubly blended with polypropylene fiber and expansion agent can most beneficially improve crack - resistance of wall filled with the stone ballast block, at the
試驗結果和理論分析證明上述試驗結果及理論分析，即單摻聚丙烯纖維、單摻膨脹劑和雙摻聚丙烯纖維與膨脹劑均能限制混凝土空心砌塊的濕漲干縮，其中，聚丙烯纖維的限制效果最好;但是，膨脹劑的補償收縮與聚丙烯纖維的限縮聯合作用使得雙摻砌塊更有利於增強混凝土空心砌塊填充墻的整體抗裂性能。 -
If stone ballast block blended with shrinkage - reducing agent, polypropylene fiber and expansion agent can reduce its own shrinkage while can ’ t worsen its own other properties, it is undoubted that modification of stone ballast block is beneficial to prevent crack in wall filled with stone ballast block, because these modification materials can respectively reduce, restrain and compensate shrinkage of concrete
在混凝土砌塊中摻加減縮劑、聚丙烯纖維和膨脹劑等減縮、限縮和補償收縮材料如能降低砌塊的收縮率，且不劣化砌塊的其它性能，則無疑有利於砌塊墻體的開裂防治。首先進行砌塊材料的改性試驗研究。
