Özet |
The production of ordinary Portland cement (OPC) requires large amounts of fuel and raw materials and responsible about 7% total CO2 emissions in the earth's atmosphere. The handicaps of the production of OPCs can extinguish with a new type of green and eco-friendly material, namely, geopolymer. The aim of the study is to investigate compressive strength properties at accelerated curing conditions of alkali-activated slag/bottom ash mortars and different rates of rice husk ash. The ratio of blast furnace slag (YFC)/fly ash (UK) was chosen 100/0, 72.5/27.5, 45/55 and 7.5/92.5, and also the ratios of alkali (YFC+ UK)/rice husk ash (PK) 0%, 2.5%, 5% and 7.5% were used. As the activator used Na2SiO4 (SS) and NaOH (SH) used was used at four different dosages, varying between 0/100%, 70/30%, 40/60% and 100/0%. Prepared using Taguchi L16 test design matrix for experimental study, and also the UK and PK to be used in the work were firstly grounded with sufficient fineness through a ball mill. The samples were poured into prismatic samples prepared in dimensions of 40 x 40 x 160 mm and thermal curing was applied at different temperatures and times. Compressive strength tests were applied on prepared 2, 7, 28 and 90 day samples. As a result of the study; it has been observed that the use of PK up to 7.5% gives favorable results in terms of compressive strength. The maximum compressive strength was obtained in 27.5% ratio of UK and 7.5% in SH and 30% in SH. However, in terms of the compressive strength, it is more appropriate to use 27.5% of the UK ratio. |
