  1. The quality of furan sand castings is usually better than clay sand castings, however, some defects are also very easy take place with furan sand castings such as blow hole, metal penetration, veining, cracking, slag inclusion, hardness too low, surface recarburation, surface sulphuration, nodularity degeneration etc, which were usually caused by improper raw materials selection, improper method design, incorrect moulding or / and core - making

    摘要呋喃樹脂砂鑄件質量一般比黏土砂鑄件好，但如果原材料選擇、工藝設計、造型和制芯操作不當，也會產生氣孔、粘砂、脈紋、裂紋，夾渣、硬度不足、滲碳、滲硫和球化不良等鑄造缺陷。
  2. Anti penetration of hardened mortar can reach 10 - 7cm / s. adopting sulfate - aluminum cement, phosphorus slag, flying ash, yellow slag and ect raw materials, the optimized mixture program of dmm is a3b3c2 ( cement 480 m2 / kg, phosphorus slag352 m2 / kg, activated agent 3 % ), 28 strength is low, due to cement alkality, resulting in activity of phosphorus slag and flying ash small

    採用硫鋁酸鹽水泥，磷渣、粉煤灰、黃砂等原武漢理工大學碩士學位論文料配製抗滲干拌砂漿最優配料方案為: a3b3c2 （水泥比表面積4som ， / kg ，磷渣比表面積352mz / kg ，激發劑3 % ） 。
  3. Internal defects : lack of penetration, lack of fusion, slag, gas pole, carck, overheating

    內部缺陷：未焊透、未熔合、夾渣、氣孔、裂紋、過熱。
  4. The one of most important factor of affecting durabilities in construction concrete is chloride deterioration. the chloride penetration current exceeds 2, 000 coulomb in the no mineral admixtures silicate cement, using 30 % ~ 40 % fly ash it falls to 800 coulomb and the 60 % micro - slag falls to 500 coulomb ; though silica fume reduces penetration current, it deteriorates the workability of concrete

    氯離子侵蝕是影響混凝土結構安全性最重要因素之一，不摻加任何礦物摻合料，氯離子滲透電量一般大於2000庫侖；粉煤灰摻量在30 40 ，滲透電量達到800庫侖；礦粉摻量在60左右，滲透電量達到500庫侖，並具有較高的綜合性能；硅灰可以改善混凝土氯離子滲透能力，但惡化了混凝土工作性。
  5. In this paper, it was mainly studied that the penetration capacity and critical content of chloride ions in concrete with different water / binder ratio, fly ash and slag under immersion and cycle of dry and wet conditions

    本文著重研究了全浸泡條件下和干濕循環條件下，氯離子在不同水膠比和不同摻量的粉煤灰、礦渣粉混凝土中的滲透性能，以及混凝土內鋼筋腐蝕的氯離子臨界濃度。
