Abstract

The present invention relates to a cement admixture composition for reducing a crack, a crack reducing dry mortar composition for pressing a rooftop that is ideally composed with the mixture, and a rooftop waterproof protecting method with the composition for pressing waterproofing layer of the rooftop after water blending the dry mortar, which are capable of effectively reducing the crack due to shrinkage reduction of a cement mixture. The cement admixture composition for reducing the crack is composed of a CaO-CaSO_4 based expanding agent and urea. The crack reducing dry mortar composition for pressing the rooftop is composed by blending a dry mortar composition mixed with cement and a fine aggregate; and the cement admixture composition for reducing the crack composed of the CaO-CaSO_4 based expanding agent and the urea. The method for protecting the waterproofing of the rooftop mixes water in the crack reducing dry mortar composition for pressing the rooftop; finishes a surface by forming the same on the rooftop in which a waterproof layer is constructed; and cures the concrete.

본 발명은 시멘트 혼합물의 수축저감에 의한 균열을 효과적으로 저감시킬 수 있는 균열저감용 시멘트 혼화제 조성물과 이를 바람직하게 포함하여 배합한 옥상 누름용 균열저감 건조 모르타르 조성물, 그리고 그 건조 모르타르를 물배합한 후 옥상 방수층 위에 누름재로 시공하는 옥상방수 보호공법에 관한 것이다. 본 발명에 따른 균열저감용 시멘트 혼화제 조성물은, 석고석회(CaO-CaSO계 팽창제와 우레아(Urea)를 포함하여 조성되는 것을 특징으로 한다. 본 발명에 따른 옥상 누름용 균열저감 건조 모르타르 조성물은 시멘트, 잔골재를 포함하여 배합되는 건조 모르타르 조성물에서, 석고석회(CaO-CaSO계 팽창제와 우레아(Urea)를 포함하여 조성한 균열저감용 시멘트 혼화제 조성물을 더 포함하여 배합되는 것을 특징으로 한다. 본 발명에 따른 옥상방수 보호공법은 상기와 같이 배합된 옥상 누름용 균열저감 모르타르 조성물에 물배합한 후, 방수층이 시공된 옥상에 타설하여 표면마무리한 다음 양생하는 것을 특징으로 한다.
