Experimental Investigation of Light Weight Concrete Using Sintered Fly Ash Aggregates

Light Weight Concrete (LWC) is popularly used in multi-story building frames, curtain walls, shell roofs, folded plates, prestressed or precast elements due to its lower dead load as compared to conventional concrete. Although it is less popular in practice because of its high-water absorption capac...

Description
Summary:Light Weight Concrete (LWC) is popularly used in multi-story building frames, curtain walls, shell roofs, folded plates, prestressed or precast elements due to its lower dead load as compared to conventional concrete. Although it is less popular in practice because of its high-water absorption capacity, high cost, lack of standard specifications, and difficulty in consistent batches. This paper presents experimental study of right proportion of different size of Sintered Light Weight Aggregate (SLWA) and its influence on fresh and mechanical properties. LWC mixes were prepared with pre-soaked aggregates of different sizes 8-12mm and 4-8 mm. Their proportioning plays an important role in the density and strength of concrete. The aggregates were mixed in various proportions of 80:20, 60:40, 40:60, and 20:80, to study the fresh and harden properties of LWC. Results showed that LWC prepared with finer aggregate (4-8mm) reduces the bulk density and enhances the mechanical properties.
