중국은 2012년 현재 시멘트 22억톤을 생산 소비하고 전세계 시멘트 생산의 60%를 차지하는 시멘트 최대 생산 소비국으로 급속한 국가경제발전과 함께 시멘트산업 역시 급성장하고 있는 대표적인 국가이다. 한편 우리나라는 시멘트 생산, 소비 면에서 세계 10위권 내의 국가임에도 규모면에서 중국의 2%에도 미치지 못하고 있다. 중국과 최근 거리에 있다는 현실을 감안할 때 향후 중국의 수급 불균형과 정책 변화에 따라 국내 시멘트 시장의 위험효소가 내재된 지정학적인 요건을 갖고 있다. 이에 최근 중국 시멘트 시장 및 기업 동향과 향후 전망을 통해 국내 시멘트시장의 현주소를 둘러보고 대비하는 계기가 되었으면 한다.

The present study concerns the acid neutralization capacity (ANC) of cement paste, mortar and concrete depending on a free water-cement ratio. The ANC of paste at 30%, 40% and 50% of water-cement ratio was measured and simultaneously the effect of aggregate on the ANC was evaluated. It was found that an increase in the acid concentration resulted in a decrease in the pH of the suspension, in particular, at 10 in the pH, a sharp decrease was observed. The ANC showed some peak resistances to acid at particular pH values.

Until now, the construction material industry has been recognized as a typical environmental destruction industry. However, recently, in order to reduce $CO_2$ emission, the main cause of environmental problems, lots of studies have been done about recycling industrial by-products and construction wastes. Therefore, the purpose of this study is to confirm whether it is possible to use as an alternative material in cement production process as a part of the development of recycled cement using an inorganic construction waste. For this study, the inorganic construction wastes was collected and analyzed each chemical component by XRF(X-ray Fluorescene). Also, the inorganic construction wastes were combined based on the chemical component of the cement, to perform this analysis. As a result, when the inorganic construction wastes was properly combined, it is possible to consider the development of the recycled cement used the inorganic construction wastes.
