In the polymer concrete composition including an aggregate and a thermosetting resin for binding the aggregate, a fine and/or coarse aggregate of the aggregate are replaced with atomized steel slag which has a high solid volume and a high density and is spherical in shape, thereby enhancing fluidity of the polymer concrete composition, reducing the amount of the thermosetting resin and increasing the amount of the aggregate per unit volume, consequently increasing engineering properties of polymer concrete products including com¬ pressive strength and fluidity and generating economic benefits.

Abstract
In the present invention, shredded tobacco materials are wound so as to have a rod-like shape using tobacco paper(or tobacco leaf), the tip end of a cigarette in the suction direction is blocked, tobacco paper(or tobacco leaf) is wound again so that a porous non-combustible material is located outside the tobacco paper winding the tobacco materials in a rod-like shape, whereby mainstream smoke generated when the tobacco materials and the inner tobacco paper are burned during smoking does not pass through the unburned tobacco material and passes through the porous non-combustible material so as to be svcked. The present invention enables reduction the number and amount of harmful substances generated in the repetitive and complex combustion process of natural tobacco and maintaining and improving taste and odor of the tobacco.
