The present invention relates to a loess-stone self-levelling mortar composition obtained by the ideal blending of a loess-stone powder having a particle size of no more than 0.1 mm and a cement, and the loess-stone powder mortar composition of the present invention is one in which from 75 to 55 percent by weight of loess-stone powder is mixed with from 25 to 45 percent by weight of a cement mixture consisting of from 30 to 50 percent by weight of ultra-rapid-hardening cement, 2 percent by weight of a polymelamine sulphonate plasticiser and from 68 to 48 percent by weight of a cement. One feature of the present invention is that it can maximise the effects of the action of loess stone and at the same time can simultaneously satisfy requirements for a high-strength binder action and a rapid-hardening action due to the cement mixture containing the ultra-rapid-hardening cement, while a second feature is that a plaster can be made by adding 33 percent by weight of water to the loess-stone powder self-levelling material and can be coated onto an interior floor surface in such a way that the mortar becomes level of its own accord and hence there is no need for separate trowel-based plastering work, and thus a flooring material can be provided which is easy to work with, is useful in environmentally friendly/healthy living environments by bringing out the useful effects of loess stone to the maximum extent even when the smoothness of the floor is uniform, and which satisfies the physical requirements sought from interior flooring materials. |
