Abstract
For recycling cement hydrate(CH) as waterproofers for mortar and concrete or a filler for rubber & plastics, the cement hydrates were treated with stearic acid(SA). And the bonding characteristics and the water repellency of the CH-SA compounds were investigated by using FT-IR, TGA, SEM, XRD, and contact angle measuring apparatus. Water tightness of the remitars used CH-SA compounds was also tested. The results are summarized as follows : 1) If the cement hydrates are treated with over 2.0% of stearic acid, the CH-SA compounds show very strong water repellency. 2) The stearic acids are solidified on the surfaces of cement hydrate in calcium stearate and aluminium stearate. 3) If CH-SA compounds which is cement hydrate treated with 5~10% of stearic acid are used 3%~6% in remitar, water absorption ratio and water permeatility ratio of remitar are decreased in below 30% of those of the ordinary remitar.
시멘트 수화물(CH)을 모르타르 콘크리트용 방수제 또는 고무 플라스틱용 충전제로 활용하기 위하여 스테아린산(SA)으로 처리하고 FT-IR, TGA, SEM, XRD, 접촉각층정기 등을 이용하여 CH-SA compound의 결합특성과 발수성을 측정하고, CH-SA compound를 레미탈에 사용하여 레미탈의 방수성을 알아 본 결과는 다음과 같이 요약된다. 1) 시멘트 수화물에 스테아린산을 2.0%이상만 처리하면 물레 대한 접촉각이
