Bearing load capacity geopolymer concrete thin wall panels under eccentric compression

Abstract EN

Due to the current diffusion of reinforced concrete (RC) walls structures and the introduction of new concrete cords, RC walls are an important structural element such as beams, plates and columns.

The experimental program included casting and testing of eight two-way thin geopolymer concrete wall panels by using local Iraqi material such as metakaolin and recycled concrete aggregate.

The specimen divided in to two groups, group (A) consists of four geopolymer concrete wall panels including recycled concrete aggregate and group (B) consists of four geopolymer concrete walls including ordinary aggregate.

In both groups the iron filings percentage volume is varying from 0 to 0.5, 0.75% and 1% .

The result showed that the load capacity of the geopolymer concrete wall panel is increased by 17% for geopolymer concrete with recycled concrete aggregate (GCRA) and 4% for geopolymer concrete with natural aggregate (GCNA) by increasing the iron filling ratio to 1% .

Also the lateral deflections decrease to 15% for geopolymer concrete with recycled concrete aggregate (GCRA) and 18% for geopolymer concrete with natural aggregate (GCNA) by increasing the iron filings ratio to Due to the current diffusion of reinforced concrete (RC) walls structures and the introduction of new concrete cords, RC walls are an important structural element such as beams, plates and columns.
