<p>PURPOSE:To effectively utilize an industrial waste by blending a latent hydraulic material with an alkaline waste water having >=pH8. CONSTITUTION:With a latent hydraulic material consisting of a glassy material containing large amounts of a granulated blastfurnace slag, a converter slag, SiO2, Al2O3 and CaO and having >=90% glass formation degree, >=1.5 basicity and 1000-10000cm<2>/g Blaine specific surface area, an alkaline waste water generated from a concrete-producing factory, etc., having >=pH8 and adjusted to be <=10wt.% slag concentration by addition of water is blended. A plasticizer such as a lignin- or melamine-based one is used in combination therewith as necessary, thus obtaining the objective concrete composition.</p> |
