| Abstract: | Influence of superfine gangue powder on durability of lightweight aggregate concrete is studied by experiments;mainly discussed influence of superfine gangue powder on frost resistance,impermeability,performance-carbonation and dry shrinkage of light aggregate concrete.The result shows that,adding superfine gangue powder in lightweight aggregate concrete can greatly improve its impermeability and frost resistance.But shrinkage ratio of the concrete will rise. |
