MANUFACTURING METHOD OF HIGH-PERFORMANCE ARTIFICIAL SEA-WEEDS BLOCKS FOR SEA-WATER PURIFICATION USING GRANULAR-ZEOLITE, RECYCLED AGGREGATES AND INDUSTRIAL BY-PRODUCTS

摘要

The present invention uses granular artificial zeolite with excellent adsorption performance of pollutants to reduce environmental pollution due to seawater pollution in coastal waters and seaports, which has recently emerged as a serious environmental problem. It relates to a method for producing multifunctional concrete for seawater purification with excellent performance.;The present invention uses the ordinary portland cement or blast furnace slag cement, the aggregate of used aggregates 5-15 mm, 15-25 mm crushed stone, KS standard waste concrete recycled aggregate or slag aggregate, the effect of seawater purification In order to increase the porosity and the strength of the binder to be maintained, the porosity is 25-35%, the water-binder ratio (mass ratio of water ÷ {binder (cement + admixture)}) 20-30%, and heavy metals such as nitrogen phosphorus Granular artificial zeolite with excellent adsorption performance of contaminants, etc. is mixed with 5 to 40% of the binder weight ratio, and blast furnace slag powder and coal ash are used as cement admixtures in the cement weight ratio of 5 to 30% and 10 to 30%, respectively. And polypropylene fiber and glass fiber mixed with 1 to 5% of the binder weight ratio to ensure crack resistance, and a high fluidizing agent is used to improve the flowability of cement paste. 0.5 ~ 3.0% by volume ratio, and high-performance AE water reducing agent is mixed with 0.2 ~ 2.5% of cement to increase the strength and workability of cement paste, forming continuous pores to form seawater purification by inflow of seawater. It is characterized by producing a multifunctional concrete for seawater purification using artificial zeolite, recycled concrete recycled aggregate and industrial by-products.;      In addition, the present invention reduces the damage caused by pollution and red tide in coastal waters by reducing seawater pollution by overnutrition salts such as nitrogen, phosphorus and heavy metals by the production of seawater purification concrete with a large amount of voids using granular artificial zeolite Recycled resources through the use of recycled concrete, blast furnace slag aggregates and industrial by-products (blast furnace slag powder, coal ash) and polypropylene fiber, a new fiber material, to improve strength, toughness and seawater purification performance.
