High strength lightweight concrete composition using sludge |
| abstract |
The present invention is a high-strength lightweight concrete composition used by replacing at least 25% of the aggregate with artificial lightweight aggregate when mixing the concrete composition by adding admixture to cement, water and aggregate, the dry weight of the unit is less than 1850 kgf / ㎥ While 28 days compressive strength is 27 MPa or more, the artificial lightweight aggregate is characterized in that the artificial lightweight aggregate made of sludge produced by molding the sludge into a spherical body and dried in air and calcined by heating to 1000 ℃. One high strength lightweight concrete composition is provided. |
