The present invention relates to a block for masonry and purification and, more particularly, to a block composition which is suitable for an eco-friendly environment while maintaining the strength of a cement block. One aspect of the present invention provides a block composition including: a stone material which includes 45 to 55 parts by weight of decomposed granite soil, 20 to 40 parts by weight of sericite, and 15 to 25 parts by weight of solidifier containing a pozzolanic mineral material; a natural mineral binder which includes alkali metal or alkaline earth metal; and an inorganic coagulant containing polyglutamic acid and calcium. Since the block of the present invention contains components returning to nature through weathering when long period of time passes after the block is discarded, the costs for processing wastes can be reduced. Also, the compressive strength of an existing cement block can be achieved, the energy used for sintering can be reduced and the emission of carbon dioxide which can be a cause of the green house effect can be suppressed by manufacturing bricks and blocks with non-sintering curing method without using an existing high temperature sintering process. |
