| Title of the article | Sludge of chemical water treatment – effective filler in self-compacting sand concrete |
| Abstract. | Self-compacting concrete is one of the modern products of building materials. The peculiarity of this concrete is its high mobility and low stratified mixture. These properties of concrete are due to the use of effective superplasticizers and fillers. To reduce costs by manufacture of self-compacting concrete must be used as fillers waste from different industries. That was done in this study. As filler was selected chemical water treatment sludge thermal power plants, stored in large quantities in the tailings ponds or industrial landfills. In the result of the research was the optimal amount of chemical water treatment sludge as part of self-compacting concrete, providing a minimum viscosity of the mixture and necessary durability of concrete. Also was selected composition sandy self-compacting concrete with application of sludge and microsilica. To determine the optimal number of fillers used a planned two-factor experiment, in which the optimal combination of microsilica and sludge. Microsilica used to improve strength properties and reduce water office developed mixtures. Developed compositions of self-packing mixes have flowability 65-70 cm, the volume of entrained air less than 3 % and the strength of 50 MPa. |
