MECHANICAL PROPERTIES OF FLY ASH AND BLAST FURNACE SLAG BASED ALKALI ACTIVATED CONCRETE

Öz

Cement is one of the commonly used materials in construction projects. In manufacture of Portland cement, clinker, which is the essential component of cement, is ground into smaller particles.  During the formation of clinker, limestone (CaCO3) is converted to lime (CaO) and carbon dioxide is emitted as a by-product of this chemical reaction.  Cement production is an environmentally hazardous process due to high carbon dioxide emission during clinker production and fossil-fuel consumption in production. Alternative construction materials which are more energy efficient and environmentally friendly can be preferred for sustainability. In order to use alternative materials and production methods, mechanical and physical properties of these materials should be examined thoroughly. In concrete production, strength, durability and workability should be in proper limits as well as considering economical factors. In this study, geopolymeric materials were used as an alternative to conventional concrete, and alkali activated concrete was produced. In this process, no cement was used. Pozzolanic materials such as fly ash and blast furnace slag were activated with alkaline liquids and gained binding property.  In production of geopolymer concrete, pozzolanic materials, aggregates and alkaline activators were used. Mechanical properties of fly ash and blast furnace slag based geopolymer concrete were investigated. Compressive strength of the cubic concrete specimens at the ages of 7 and 28 days was determined and the effect of ambient conditions on geopolymer concrete was examined. As a result, it was found that the increase in the amount of blast furnace slag resulted in higher compressive strength values.
