INTENSIFICATION OF GEOCRETE BEAM WITH GFRP USING ABAQUS

Concrete is a versatile material having number of desirable properties, so widely preferred in construction industry. But major disadvantage that under severe vibrations such as earthquakes it gets cracked and concrete has poor modification repair quality. Therefore some or strengthening must be performed damaged element stand for further useful life. Many civil structures are no longer considered safe due to increased load specifications the design codes. Such strengthened order maintain their serviceability[4]. As demand increases, Portland cement also increases. It estimated production will increase from about 1.5 billion tons 1995 2.5 2015. On other hand, climate change global warming caused by emission greenhouse gases, carbon dioxide (CO2), into atmosphere human activities. Among CO2 contributes 65% warming. The industry held responsible emissions, because one ton emits approximately atmosphere. Several efforts progress reduce use address issues. These include utilization supplementary cementing materials fly ash, silica fume, granulated blast furnace slag, rice-husk ash metakaolin, development alternative binders cement. In this respect, geopolymer technology proposed Davidovits shows considerable promise application an binder terms warming, could significantly industries [13]. 1978, Professor Joseph introduced mineral with amorphous structure, named geopolymers. (1988; 1994) alkaline liquid used react silicon (Si) aluminium (Al) source geological origin by-product rice husk produce binders. Because chemical reaction takes place case polymerization process, he coined term ‘Geopolymer’ represent these This was class solid materials, producedby alumino silicate powder liquid. initial goal research done on geopolymers find more fire resistant high amount fires Europe at time. led being coatings protection cruise ships thermal protect results low flexural strength. Brittleness both types compensated conventional steel reinforcement [18].
