<p>The present invention relates to a block composition which increases simultaneously the degree of reuse using an alum sludge, which is an industrial byproduct, and bottom ashes obtained from a thermal power station as byproduct; adds horse droppings, which is other wastes, to a mixed raw material to age the mixed raw material and adds laterite, general aggregate or a raw material, or a strength reinforcing material having a far infrared radiation function to the resulting object. According to the present invention, a method of manufacturing an environmentally friendly block using an alum sludge includes: a first step of obtaining a calcium carbonate (CaCO_3) containing reactant by mixing an alum sludge having a water content in the range of 15-25% with a bottom ash obtained from a thermal power station with a ratio of the alum sludge to the bottom ash of 40±10 : 60±10 wt parts to react calcium oxide (CaO) component included in the bottom ash with a moisture (H_2O) in the sludge; a second step of mixing the calcium carbonate (CaCO_3) containing reactant obtained in the first step and horse droppings with a ratio of horse droppings 30±10 wt part based on the calcium carbonate (CaCO_3) containing reactant 70±10 wt parts to age an aging reactant; and a third step of mixing the aging reactant from the second step with laterite and general aggregate or a raw material with a ratio of the laterite 25±5 wt parts and the general aggregate or raw material 25±5 wt part based on the aging reactant 50±10 wt parts and pressing the mixture by a press to obtain a block product.</p> |
