Abstract:

 


In the production of concrete and ferroconcrete elements, the usage of pozzolanic industrial wastes such as fly ash (FA), silica fume (SF), blast furnace slag (GBS) and metakaolin (MK) has a successful background. High- reactivity metakaolin(MK) is a manufactured pozzolan produced by thermal processing of purified kaolinitic clay. In this study, in concrete and mortars made with aggregates including alkali-silica, the metakaolin effect, pozzolanic activity experiment, concrete pressure strength were investigated by alkali- silica reaction (ASR) experiments affecting the durability in concrete and mortars. As a result of puzzolanic activity experiment, it is provided pressure strength at the rate of 95% (0.95) for a 28-day value. In the results of Accelerated mortar bar experiment, the formation of alkali silica reaction (ASR) affecting concrete strength was made harmless by the use of metakaolin at certain rates. In the samples with the additive at the rates of 10, 15 and 20%, the formation of alkali- silica reaction (ASR) was seen to fall below the limit of 0,10% that is a standard value. At the end of experiment time, control sample becomes "secure amount" in which minimum additive amount that reduces alkali- silica reaction dilatations below the value of 0.10% can be used. According to pressure strength results, it was detected that the usage of metakaolin (MK) positively affected the mechanical features of the concrete, increased the strength and improved the creep and permeability properties of the concrete. Ideal additive amount must be 10% in terms of the formation of ASR and pressure strength. Being ceased of the puzzolanic additives to be wastes and spreading its usage in terms of contributing to the economy will be suitable. In the concretes prepared with true mixtures, multi-dimensional acquisitions will be achieved in terms of strength and this will prolong the service durability of concrete structures.
